version: Bump revision number

Rather than systematically clearing the buffer on reset(), record the
timestamp of the last entry and use it to filter-out old entries in
DmesgCollector.entries property.

This also allows detecting if the ring buffer has ran out of memory, or
if something has cleared the buffer while collecting, leading to missing
entries.

+Version 2.1, February 1999

+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be

+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author

+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License

+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+Version 2.1, February 1999

+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by
+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in

+and labelled as such in comments in the individual source files. All
+have been licensed under extremely permissive terms.
+
+The ARM memcpy code (src/string/arm/memcpy.S) is Copyright © 2008
+The Android Open Source Project and is licensed under a two-clause BSD
+license. It was taken from Bionic libc, used on Android.
+
+The AArch64 memcpy and memset code (src/string/aarch64/*) are
+Copyright © 1999-2019, Arm Limited.
+
+The implementation of DES for crypt (src/crypt/crypt_des.c) is
+Copyright © 1994 David Burren. It is licensed under a BSD license.
+
+The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
+originally written by Solar Designer and placed into the public

+in jurisdictions that may not recognize the public domain.
+
+The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
+Valentin Ochs and is licensed under an MIT-style license.
+
+The x86_64 port was written by Nicholas J. Kain and is licensed under
+the standard MIT terms.
+
+The mips and microblaze ports were originally written by Richard
+Pennington for use in the ellcc project. The original code was adapted
+by Rich Felker for build system and code conventions during upstream
+integration. It is licensed under the standard MIT terms.
+
+The mips64 port was contributed by Imagination Technologies and is

+
+The powerpc port was also originally written by Richard Pennington,
+and later supplemented and integrated by John Spencer. It is licensed
+under the standard MIT terms.
+
+All other files which have no copyright comments are original works
+produced specifically for use as part of this library, written either

+contibutors listed above. Details on authorship of individual files
+can be found in the git version control history of the project. The

+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+The TRE regular expression implementation (src/regex/reg* and
+src/regex/tre*) is Copyright © 2001-2008 Ville Laurikari and licensed
+under a 2-clause BSD license (license text in the source files). The
+included version has been heavily modified by Rich Felker in 2012, in
+the interests of size, simplicity, and namespace cleanliness.
+
+Much of the math library code (src/math/* and src/complex/*) is
+Copyright © 1993,2004 Sun Microsystems or
+Copyright © 2003-2011 David Schultz or
+Copyright © 2003-2009 Steven G. Kargl or

+Copyright © 2017-2018 Arm Limited
+and labelled as such in comments in the individual source files. All
+have been licensed under extremely permissive terms.
+
+The ARM memcpy code (src/string/arm/memcpy.S) is Copyright © 2008
+The Android Open Source Project and is licensed under a two-clause BSD
+license. It was taken from Bionic libc, used on Android.
+
+The AArch64 memcpy and memset code (src/string/aarch64/*) are
+Copyright © 1999-2019, Arm Limited.
+
+The implementation of DES for crypt (src/crypt/crypt_des.c) is
+Copyright © 1994 David Burren. It is licensed under a BSD license.
+
+The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was
+originally written by Solar Designer and placed into the public
+domain. The code also comes with a fallback permissive license for use
+in jurisdictions that may not recognize the public domain.
+
+The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
+Valentin Ochs and is licensed under an MIT-style license.
+
+The x86_64 port was written by Nicholas J. Kain and is licensed under
+the standard MIT terms.
+
+The mips and microblaze ports were originally written by Richard
+Pennington for use in the ellcc project. The original code was adapted
+by Rich Felker for build system and code conventions during upstream
+integration. It is licensed under the standard MIT terms.
+
+The mips64 port was contributed by Imagination Technologies and is
+licensed under the standard MIT terms.
+
+The powerpc port was also originally written by Richard Pennington,
+and later supplemented and integrated by John Spencer. It is licensed
+under the standard MIT terms.
+
+All other files which have no copyright comments are original works
+produced specifically for use as part of this library, written either
+by Rich Felker, the main author of the library, or by one or more
+contibutors listed above. Details on authorship of individual files
+can be found in the git version control history of the project. The
+omission of copyright and license comments in each file is in the
+interest of source tree size.
+
+In addition, permission is hereby granted for all public header files
+(include/* and arch/*/bits/*) and crt files intended to be linked into
+applications (crt/*, ldso/dlstart.c, and arch/*/crt_arch.h) to omit
+the copyright notice and permission notice otherwise required by the
+license, and to use these files without any requirement of
+attribution. These files include substantial contributions from:
+
+Bobby Bingham
+John Spencer
+Nicholas J. Kain
+Rich Felker
+Richard Pennington
+Stefan Kristiansson
+Szabolcs Nagy
+
+all of whom have explicitly granted such permission.
+
+This file previously contained text expressing a belief that most of
+the files covered by the above exception were sufficiently trivial not
+to be subject to copyright, resulting in confusion over whether it
+negated the permissions granted in the license. In the spirit of
+permissive licensing, and of not having licensing issues being an
+obstacle to adoption, that text has been removed.

+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it

+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License

+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+Version 2.1, February 1999
+
+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by
+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by
+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in

+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author

+This library is distributed in the hope that it will be useful, but WITHOUT

+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if

+                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.

+Version 2.1, February 1999
+
+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by
+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in

+
+The ARM memcpy code (src/string/arm/memcpy.S) is Copyright © 2008
+The Android Open Source Project and is licensed under a two-clause BSD

+
+The implementation of blowfish crypt (src/crypt/crypt_blowfish.c) was

+in jurisdictions that may not recognize the public domain.
+
+The smoothsort implementation (src/stdlib/qsort.c) is Copyright © 2011
+Valentin Ochs and is licensed under an MIT-style license.
+
+The x86_64 port was written by Nicholas J. Kain and is licensed under
+the standard MIT terms.
+
+The mips and microblaze ports were originally written by Richard
+Pennington for use in the ellcc project. The original code was adapted
+by Rich Felker for build system and code conventions during upstream

+
+The mips64 port was contributed by Imagination Technologies and is

+
+The powerpc port was also originally written by Richard Pennington,

+
+All other files which have no copyright comments are original works

+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it

+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License

+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if

+                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Version 2.1, February 1999

+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by
+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+Version 2.1, February 1999

+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts as
+the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some specially
+designated software packages--typically libraries--of the Free Software
+Foundation and other authors who decide to use it. You can use it too, but
+we suggest you first think carefully about whether this license or the
+ordinary General Public License is the better strategy to use in any
+particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price. Our General Public Licenses are designed to make sure that you have
+the freedom to distribute copies of free software (and charge for this
+service if you wish); that you receive source code or can get it if you
+want it; that you can change the software and use pieces of it in new free
+programs; and that you are informed that you can do these things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for you if
+you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or for
+a fee, you must give the recipients all the rights that we gave you. You
+must make sure that they, too, receive or can get the source code. If you
+link other code with the library, you must provide complete object files to
+the recipients, so that they can relink them with the library after making
+changes to the library and recompiling it. And you must show them these
+terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is no
+warranty for the free library. Also, if the library is modified by someone
+else and passed on, the recipients should know that what they have is not
+the original version, so that the original author's reputation will not be
+affected by problems that might be introduced by others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program. We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder. Therefore, we insist that any patent license obtained
+for a version of the library must be consistent with the full freedom of
+use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License. This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License. We use this license for certain
+libraries in order to permit linking those libraries into non-free
+programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a combined
+work, a derivative of the original library. The ordinary General Public
+License therefore permits such linking only if the entire combination fits
+its criteria of freedom. The Lesser General Public License permits more lax
+criteria for linking other code with the library.
+
+We call this license the "Lesser" General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License. It also provides other free software developers Less of an
+advantage over competing non-free programs. These disadvantages are the
+reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a de-facto
+standard. To achieve this, non-free programs must be allowed to use the
+library. A more frequent case is that a free library does the same job as
+widely used non-free libraries. In this case, there is little to gain by
+limiting the free library to free software only, so we use the Lesser
+General Public License.
+
+In other cases, permission to use a particular library in non-free programs
+enables a greater number of people to use a large body of free
+software. For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system, as
+well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the users'
+freedom, it does ensure that the user of a program that is linked with the
+Library has the freedom and the wherewithal to run that program using a
+modified version of the Library.
+
+The precise terms and conditions for copying, distribution and modification
+follow. Pay close attention to the difference between a "work based on the
+library" and a "work that uses the library". The former contains code
+derived from the library, whereas the latter must be combined with the
+library in order to run.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library or other program
+   which contains a notice placed by the copyright holder or other
+   authorized party saying it may be distributed under the terms of this
+   Lesser General Public License (also called "this License"). Each
+   licensee is addressed as "you".
+
+   A "library" means a collection of software functions and/or data
+   prepared so as to be conveniently linked with application programs
+   (which use some of those functions and data) to form executables.
+
+   The "Library", below, refers to any such software library or work which
+   has been distributed under these terms. A "work based on the Library"
+   means either the Library or any derivative work under copyright law:
+   that is to say, a work containing the Library or a portion of it, either
+   verbatim or with modifications and/or translated straightforwardly into
+   another language. (Hereinafter, translation is included without
+   limitation in the term "modification".)
+
+   "Source code" for a work means the preferred form of the work for making
+   modifications to it. For a library, complete source code means all the
+   source code for all modules it contains, plus any associated interface
+   definition files, plus the scripts used to control compilation and
+   installation of the library.
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    a program using the Library is not restricted, and output from such a
+    program is covered only if its contents constitute a work based on the
+    Library (independent of the use of the Library in a tool for writing
+    it). Whether that is true depends on what the Library does and what the
+    program that uses the Library does.
+
+1. You may copy and distribute verbatim copies of the Library's complete
+   source code as you receive it, in any medium, provided that you
+   conspicuously and appropriately publish on each copy an appropriate
+   copyright notice and disclaimer of warranty; keep intact all the notices
+   that refer to this License and to the absence of any warranty; and
+   distribute a copy of this License along with the Library.
+
+   You may charge a fee for the physical act of transferring a copy, and
+   you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Library or any portion of it,
+   thus forming a work based on the Library, and copy and distribute such
+   modifications or work under the terms of Section 1 above, provided that
+   you also meet all of these conditions:
+
+   a) The modified work must itself be a software library.
+
+   b) You must cause the files modified to carry prominent notices stating
+      that you changed the files and the date of any change.
+
+   c) You must cause the whole of the work to be licensed at no charge to
+      all third parties under the terms of this License.
+
+   d) If a facility in the modified Library refers to a function or a table
+      of data to be supplied by an application program that uses the
+      facility, other than as an argument passed when the facility is
+      invoked, then you must make a good faith effort to ensure that, in
+      the event an application does not supply such function or table, the
+      facility still operates, and performs whatever part of its purpose
+      remains meaningful.
+
+   (For example, a function in a library to compute square roots has a
+    purpose that is entirely well-defined independent of the
+    application. Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must be
+    optional: if the application does not supply it, the square root
+    function must still compute square roots.)
+
+   These requirements apply to the modified work as a whole. If
+   identifiable sections of that work are not derived from the Library, and
+   can be reasonably considered independent and separate works in
+   themselves, then this License, and its terms, do not apply to those
+   sections when you distribute them as separate works. But when you
+   distribute the same sections as part of a whole which is a work based on
+   the Library, the distribution of the whole must be on the terms of this
+   License, whose permissions for other licensees extend to the entire
+   whole, and thus to each and every part regardless of who wrote it.
+
+   Thus, it is not the intent of this section to claim rights or contest
+   your rights to work written entirely by you; rather, the intent is to
+   exercise the right to control the distribution of derivative or
+   collective works based on the Library.
+
+   In addition, mere aggregation of another work not based on the Library
+   with the Library (or with a work based on the Library) on a volume of a
+   storage or distribution medium does not bring the other work under the
+   scope of this License.
+
+3. You may opt to apply the terms of the ordinary GNU General Public
+   License instead of this License to a given copy of the Library. To do
+   this, you must alter all the notices that refer to this License, so that
+   they refer to the ordinary GNU General Public License, version 2,
+   instead of to this License. (If a newer version than version 2 of the
+   ordinary GNU General Public License has appeared, then you can specify
+   that version instead if you wish.) Do not make any other change in these
+   notices.
+
+   Once this change is made in a given copy, it is irreversible for that
+   copy, so the ordinary GNU General Public License applies to all
+   subsequent copies and derivative works made from that copy.
+
+   This option is useful when you wish to copy part of the code of the
+   Library into a program that is not a library.
+
+4. You may copy and distribute the Library (or a portion or derivative of
+   it, under Section 2) in object code or executable form under the terms
+   of Sections 1 and 2 above provided that you accompany it with the
+   complete corresponding machine-readable source code, which must be
+   distributed under the terms of Sections 1 and 2 above on a medium
+   customarily used for software interchange.
+
+   If distribution of object code is made by offering access to copy from a
+   designated place, then offering equivalent access to copy the source
+   code from the same place satisfies the requirement to distribute the
+   source code, even though third parties are not compelled to copy the
+   source along with the object code.
+
+5. A program that contains no derivative of any portion of the Library, but
+   is designed to work with the Library by being compiled or linked with
+   it, is called a "work that uses the Library". Such a work, in isolation,
+   is not a derivative work of the Library, and therefore falls outside the
+   scope of this License.
+
+   However, linking a "work that uses the Library" with the Library creates
+   an executable that is a derivative of the Library (because it contains
+   portions of the Library), rather than a "work that uses the
+   library". The executable is therefore covered by this License. Section 6
+   states terms for distribution of such executables.
+
+   When a "work that uses the Library" uses material from a header file
+   that is part of the Library, the object code for the work may be a
+   derivative work of the Library even though the source code is
+   not. Whether this is true is especially significant if the work can be
+   linked without the Library, or if the work is itself a library. The
+   threshold for this to be true is not precisely defined by law.
+
+   If such an object file uses only numerical parameters, data structure
+   layouts and accessors, and small macros and small inline functions (ten
+   lines or less in length), then the use of the object file is
+   unrestricted, regardless of whether it is legally a derivative
+   work. (Executables containing this object code plus portions of the
+   Library will still fall under Section 6.)
+
+   Otherwise, if the work is a derivative of the Library, you may
+   distribute the object code for the work under the terms of Section
+   6. Any executables containing that work also fall under Section 6,
+   whether or not they are linked directly with the Library itself.
+
+6. As an exception to the Sections above, you may also combine or link a
+   "work that uses the Library" with the Library to produce a work
+   containing portions of the Library, and distribute that work under terms
+   of your choice, provided that the terms permit modification of the work
+   for the customer's own use and reverse engineering for debugging such
+   modifications.
+
+   You must give prominent notice with each copy of the work that the
+   Library is used in it and that the Library and its use are covered by
+   this License. You must supply a copy of this License. If the work during
+   execution displays copyright notices, you must include the copyright
+   notice for the Library among them, as well as a reference directing the
+   user to the copy of this License. Also, you must do one of these things:
+
+   a) Accompany the work with the complete corresponding machine-readable
+      source code for the Library including whatever changes were used in
+      the work (which must be distributed under Sections 1 and 2 above);
+      and, if the work is an executable linked with the Library, with the
+      complete machine-readable "work that uses the Library", as object
+      code and/or source code, so that the user can modify the Library and
+      then relink to produce a modified executable containing the modified
+      Library. (It is understood that the user who changes the contents of
+      definitions files in the Library will not necessarily be able to
+      recompile the application to use the modified definitions.)
+
+   b) Use a suitable shared library mechanism for linking with the
+      Library. A suitable mechanism is one that (1) uses at run time a copy
+      of the library already present on the user's computer system, rather
+      than copying library functions into the executable, and (2) will
+      operate properly with a modified version of the library, if the user
+      installs one, as long as the modified version is interface-compatible
+      with the version that the work was made with.
+
+   c) Accompany the work with a written offer, valid for at least three
+      years, to give the same user the materials specified in Subsection
+      6a, above, for a charge no more than the cost of performing this
+      distribution.
+
+   d) If distribution of the work is made by offering access to copy from a
+      designated place, offer equivalent access to copy the above specified
+      materials from the same place.
+
+   e) Verify that the user has already received a copy of these materials
+      or that you have already sent this user a copy.
+
+   For an executable, the required form of the "work that uses the Library"
+   must include any data and utility programs needed for reproducing the
+   executable from it. However, as a special exception, the materials to be
+   distributed need not include anything that is normally distributed (in
+   either source or binary form) with the major components (compiler,
+   kernel, and so on) of the operating system on which the executable runs,
+   unless that component itself accompanies the executable.
+
+   It may happen that this requirement contradicts the license restrictions
+   of other proprietary libraries that do not normally accompany the
+   operating system. Such a contradiction means you cannot use both them
+   and the Library together in an executable that you distribute.
+
+7. You may place library facilities that are a work based on the Library
+   side-by-side in a single library together with other library facilities
+   not covered by this License, and distribute such a combined library,
+   provided that the separate distribution of the work based on the Library
+   and of the other library facilities is otherwise permitted, and provided
+   that you do these two things:
+
+   a) Accompany the combined library with a copy of the same work based on
+      the Library, uncombined with any other library facilities. This must
+      be distributed under the terms of the Sections above.
+
+   b) Give prominent notice with the combined library of the fact that part
+      of it is a work based on the Library, and explaining where to find
+      the accompanying uncombined form of the same work.
+
+8. You may not copy, modify, sublicense, link with, or distribute the
+   Library except as expressly provided under this License. Any attempt
+   otherwise to copy, modify, sublicense, link with, or distribute the
+   Library is void, and will automatically terminate your rights under this
+   License. However, parties who have received copies, or rights, from you
+   under this License will not have their licenses terminated so long as
+   such parties remain in full compliance.
+
+9. You are not required to accept this License, since you have not signed
+   it. However, nothing else grants you permission to modify or distribute
+   the Library or its derivative works. These actions are prohibited by law
+   if you do not accept this License. Therefore, by modifying or
+   distributing the Library (or any work based on the Library), you
+   indicate your acceptance of this License to do so, and all its terms and
+   conditions for copying, distributing or modifying the Library or works
+   based on it.
+
+10. Each time you redistribute the Library (or any work based on the
+    Library), the recipient automatically receives a license from the
+    original licensor to copy, distribute, link with or modify the Library
+    subject to these terms and conditions. You may not impose any further
+    restrictions on the recipients' exercise of the rights granted
+    herein. You are not responsible for enforcing compliance by third
+    parties with this License.
+
+11. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot
+    distribute so as to satisfy simultaneously your obligations under this
+    License and any other pertinent obligations, then as a consequence you
+    may not distribute the Library at all. For example, if a patent license
+    would not permit royalty-free redistribution of the Library by all
+    those who receive copies directly or indirectly through you, then the
+    only way you could satisfy both it and this License would be to refrain
+    entirely from distribution of the Library.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply, and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up
+    to the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to
+    be a consequence of the rest of this License.
+
+12. If the distribution and/or use of the Library is restricted in certain
+    countries either by patents or by copyrighted interfaces, the original
+    copyright holder who places the Library under this License may add an
+    explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+13. The Free Software Foundation may publish revised and/or new versions of
+    the Lesser General Public License from time to time. Such new versions
+    will be similar in spirit to the present version, but may differ in
+    detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Library
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Library does not specify a license
+    version number, you may choose any version ever published by the Free
+    Software Foundation.
+
+14. If you wish to incorporate parts of the Library into other free
+    programs whose distribution conditions are incompatible with these,
+    write to the author to ask for permission. For software which is
+    copyrighted by the Free Software Foundation, write to the Free Software
+    Foundation; we sometimes make exceptions for this. Our decision will be
+    guided by the two goals of preserving the free status of all
+    derivatives of our free software and of promoting the sharing and reuse
+    of software generally.
+
+NO WARRANTY
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+one line to give the library's name and an idea of what it does.
+Copyright (C) year name of author
+
+This library is free software; you can redistribute it and/or modify it
+under the terms of the GNU Lesser General Public License as published by
+the Free Software Foundation; either version 2.1 of the License, or (at
+your option) any later version.
+
+This library is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License
+for more details.
+
+You should have received a copy of the GNU Lesser General Public License
+along with this library; if not, write to the Free Software Foundation,
+Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add
+information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in

+                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.
