-Much like less(1) does, {{PROJECT_EXECUTABLE}} supports input preprocessors via the LESSOPEN and LESSCLOSE environment variables.

-
-To use the preprocessor, call:
-
-\fB{{PROJECT_EXECUTABLE}} --lessopen\fR

-Alternatively, the preprocessor may be enabled by default by adding the '\-\-lessopen' option to the configuration file.

-:h[elp]			Open a window and display the help file in read-only
-			mode.  If there is a help window open already, use
-			that one.  Otherwise, if the current window uses the
-			full width of the screen or is at least 80 characters
-			wide, the help window will appear just above the
-			current window.  Otherwise the new window is put at
-			the very top.
-			The 'helplang' option is used to select a language, if
-#      ^ punctuation.definition.link.option.begin
-#       ^^^^^^^^ markup.underline.link.option
-#               ^ punctuation.definition.link.option.end
-			the main help file is available in several languages.
-
-			Type |gO| to see the table of contents.
-
-						*{subject}* *E149* *E661*
-:h[elp] {subject}	Like ":help", additionally jump to the tag {subject}.
-			For example:  >
-				:help options
-
-<			{subject} can include wildcards such as "*", "?" and
-#   ^ punctuation.definition.constant.begin
-#    ^^^^^^^ constant.numeric
-#           ^ punctuation.definition.constant.end
-			"[a-z]":
-			   :help z?	jump to help for any "z" command
-			   :help z.	jump to the help for "z."
-			But when a tag exists it is taken literally:
-			   :help :?	jump to help for ":?"
-
-			If there is no full match for the pattern, or there
-			are several matches, the "best" match will be used.
-			A sophisticated algorithm is used to decide which
-			match is better than another one.  These items are
-			considered in the computation:
-			- A match with same case is much better than a match
-			  with different case.
-			- A match that starts after a non-alphanumeric
-			  character is better than a match in the middle of a
-			  word.
-			- A match at or near the beginning of the tag is
-			  better than a match further on.
-			- The more alphanumeric characters match, the better.
-			- The shorter the length of the match, the better.
-
-			The 'helplang' option is used to select a language, if
-			the {subject} is available in several languages.
-			To find a tag in a specific language, append "@ab",
-			where "ab" is the two-letter language code.  See
-			|help-translated|.
-
-			Note that the longer the {subject} you give, the less
-			matches will be found.  You can get an idea how this
-			all works by using commandline completion (type CTRL-D
-#                                                  ^^^^^^ markup.underline.link.key
-			after ":help subject" |c_CTRL-D|).
-			If there are several matches, you can have them listed
-			by hitting CTRL-D.  Example: >
-				:help cont<Ctrl-D>
-
-<			Instead of typing ":help CTRL-V" to search for help
-			for CTRL-V you can type: >
-				:help ^V
-<			This also works together with other characters, for
-			example to find help for CTRL-V in Insert mode: >
-				:help i^V
-<
-			It is also possible to first do ":help" and then
-			use ":tag {pattern}" in the help window.  The
-			":tnext" command can then be used to jump to other
-			matches, "tselect" to list matches and choose one. >
-				:help index
-				:tselect /.*mode
-
-<			When there is no argument you will see matches for
-			"help", to avoid listing all possible matches (that
-			would be very slow).
-			The number of matches displayed is limited to 300.
-
-			The `:help` command can be followed by '|' and another
-			command, but you don't need to escape the '|' inside a
-			help command.  So these both work: >
-				:help |
-				:help k| only
-<			Note that a space before the '|' is seen as part of
-#   ^^^^ constant.other.note
-			the ":help" argument.
-			You can also use <NL> or <CR> to separate the help
-			command from a following command.  You need to type
-			CTRL-V first to insert the <NL> or <CR>.  Example: >
-				:help so<C-V><CR>only
-<
-
-:h[elp]! [subject]	Like ":help", but in non-English help files prefer to
-			find a tag in a file with the same language as the
-			current file.  See |help-translated|.
-
-							*:helpc* *:helpclose*
-:helpc[lose]		Close one help window, if there is one.
-			Vim will try to restore the window layout (including
-			cursor position) to the same layout it was before
-			opening the help window initially.  This might cause
-			triggering several autocommands.
-
-							*:helpg* *:helpgrep*
-:helpg[rep] {pattern}[@xx]
-			Search all help text files and make a list of lines
-			in which {pattern} matches.  Jumps to the first match.
-			The optional [@xx] specifies that only matches in the
-			"xx" language are to be found.
-			You can navigate through the matches with the
-			|quickfix| commands, e.g., |:cnext| to jump to the
-			next one.  Or use |:cwindow| to get the list of
-			matches in the quickfix window.
-			{pattern} is used as a Vim regexp |pattern|.
-			'ignorecase' is not used, add "\c" to ignore case.
-			Example for case sensitive search: >
-				:helpgrep Uganda
-<			Example for case ignoring search: >
-				:helpgrep uganda\c
-<			Example for searching in French help: >
-				:helpgrep backspace@fr
-<			The pattern does not support line breaks, it must
-			match within one line.  You can use |:grep| instead,
-			but then you need to get the list of help files in a
-			complicated way.
-			Cannot be followed by another command, everything is
-			used as part of the pattern.  But you can use
-			|:execute| when needed.
-			Compressed help files will not be searched (Fedora
-			compresses the help files).
-
-							*:lh* *:lhelpgrep*
-:lh[elpgrep] {pattern}[@xx]
-			Same as ":helpgrep", except the location list is used
-			instead of the quickfix list.  If the help window is
-			already opened, then the location list for that window
-			is used.  Otherwise, a new help window is opened and
-			the location list for that window is set.  The
-			location list for the current window is not changed
-			then.
-
-							*:exu* *:exusage*
-:exu[sage]		Show help on Ex commands.  Added to simulate the Nvi
-			command.
-
-							*:viu* *:viusage*
-:viu[sage]		Show help on Normal mode commands.  Added to simulate
-			the Nvi command.
-
-When no argument is given to |:help| the file given with the 'helpfile' option
-will be opened.  Otherwise the specified tag is searched for in all "doc/tags"
-files in the directories specified in the 'runtimepath' option.
-
-If you would like to open the help in the current window, see this tip:
-|help-curwin|.
-
-The initial height of the help window can be set with the 'helpheight' option
-(default 20).
-						*help-buffer-options*
-When the help buffer is created, several local options are set to make sure
-the help text is displayed as it was intended:
-    'iskeyword'		nearly all ASCII chars except ' ', '*', '"' and '|'
-    'foldmethod'	"manual"
-    'tabstop'		8
-    'arabic'		off
-    'binary'		off
-    'buflisted'		off
-    'cursorbind'	off
-    'diff'		off
-    'foldenable'	off
-    'list'		off
-    'modifiable'	off
-    'number'		off
-    'relativenumber'	off
-    'rightleft'		off
-    'scrollbind'	off
-    'spell'		off
-
-Jump to specific subjects by using tags.  This can be done in two ways:
-- Use the "CTRL-]" command while standing on the name of a command or option.
-  This only works when the tag is a keyword.  "<C-Leftmouse>" and
-  "g<LeftMouse>" work just like "CTRL-]".
-- use the ":ta {subject}" command.  This also works with non-keyword
-  characters.
-
-Use CTRL-T or CTRL-O to jump back.
-Use ":q" to close the help window.
-
-If there are several matches for an item you are looking for, this is how you
-can jump to each one of them:
-1. Open a help window
-2. Use the ":tag" command with a slash prepended to the tag.  E.g.: >
-	:tag /min
-3. Use ":tnext" to jump to the next matching tag.
-
-It is possible to add help files for plugins and other items.  You don't need
-to change the distributed help files for that.  See |add-local-help|.
-
-To write a local help file, see |write-local-help|.
-
-Note that the title lines from the local help files are automagically added to
-the "LOCAL ADDITIONS" section in the "help.txt" help file |local-additions|.
-This is done when viewing the file in Vim, the file itself is not changed.  It
-is done by going through all help files and obtaining the first line of each
-file.  The files in $VIMRUNTIME/doc are skipped.
-
-							*help-xterm-window*
-If you want to have the help in another xterm window, you could use this
-command: >
-	:!xterm -e vim +help &
-<
-
-					*:helpt* *:helptags*
-			*E150* *E151* *E152* *E153* *E154* *E670* *E856*
-:helpt[ags] [++t] {dir}
-			Generate the help tags file(s) for directory {dir}.
-			When {dir} is ALL then all "doc" directories in
-			'runtimepath' will be used.
-
-			All "*.txt" and "*.??x" files in the directory and
-			sub-directories are scanned for a help tag definition
-			in between stars.  The "*.??x" files are for
-			translated docs, they generate the "tags-??" file, see
-			|help-translated|.  The generated tags files are
-			sorted.
-			When there are duplicates an error message is given.
-			An existing tags file is silently overwritten.
-
-			The optional "++t" argument forces adding the
-			"help-tags" tag.  This is also done when the {dir} is
-			equal to $VIMRUNTIME/doc.
-
-			To rebuild the help tags in the runtime directory
-			(requires write permission there): >
-				:helptags $VIMRUNTIME/doc
-<
-
-
-==============================================================================
-2. Translated help files				*help-translated*
-
-It is possible to add translated help files, next to the original English help
-files.  Vim will search for all help in "doc" directories in 'runtimepath'.
-
-At this moment translations are available for:
-	Chinese  - multiple authors
-	French   - translated by David Blanchet
-	Italian  - translated by Antonio Colombo
-	Japanese - multiple authors
-	Polish   - translated by Mikolaj Machowski
-	Russian  - translated by Vassily Ragosin
-See the Vim website to find them: http://www.vim.org/translations.php
-
-A set of translated help files consists of these files:
-
-	help.abx
-	howto.abx
-	...
-	tags-ab
-
-"ab" is the two-letter language code.  Thus for Italian the names are:
-
-	help.itx
-	howto.itx
-	...
-	tags-it
-
-The 'helplang' option can be set to the preferred language(s).  The default is
-set according to the environment.  Vim will first try to find a matching tag
-in the preferred language(s).  English is used when it cannot be found.
-
-To find a tag in a specific language, append "@ab" to a tag, where "ab" is the
-two-letter language code.  Example: >
-	:he user-manual@it
-	:he user-manual@en
-The first one finds the Italian user manual, even when 'helplang' is empty.
-The second one finds the English user manual, even when 'helplang' is set to
-"it".
-
-When using command-line completion for the ":help" command, the "@en"
-extension is only shown when a tag exists for multiple languages.  When the
-tag only exists for English "@en" is omitted.  When the first candidate has an
-"@ab" extension and it matches the first language in 'helplang' "@ab" is also
-omitted.
-
-When using |CTRL-]| or ":help!" in a non-English help file Vim will try to
-find the tag in the same language.  If not found then 'helplang' will be used
-to select a language.
-
-Help files must use latin1 or utf-8 encoding.  Vim assumes the encoding is
-utf-8 when finding non-ASCII characters in the first line.  Thus you must
-translate the header with "For Vim version".
-
-The same encoding must be used for the help files of one language in one
-directory.  You can use a different encoding for different languages and use
-a different encoding for help files of the same language but in a different
-directory.
-
-Hints for translators:
-- Do not translate the tags.  This makes it possible to use 'helplang' to
-  specify the preferred language.  You may add new tags in your language.
-- When you do not translate a part of a file, add tags to the English version,
-  using the "tag@en" notation.
-- Make a package with all the files and the tags file available for download.
-  Users can drop it in one of the "doc" directories and start use it.
-  Report this to Bram, so that he can add a link on www.vim.org.
-- Use the |:helptags| command to generate the tags files.  It will find all
-  languages in the specified directory.
-
-==============================================================================
-3. Writing help files					*help-writing*
-
-For ease of use, a Vim help file for a plugin should follow the format of the
-standard Vim help files, except for the first line.  If you are writing a new
-help file it's best to copy one of the existing files and use it as a
-template.
-
-The first line in a help file should have the following format:
-
-*plugin_name.txt*	{short description of the plugin}
-
-The first field is a help tag where ":help plugin_name" will jump to.  The
-remainder of the line, after a Tab, describes the plugin purpose in a short
-way.  This will show up in the "LOCAL ADDITIONS" section of the main help
-file.  Check there that it shows up properly: |local-additions|.
-
-If you want to add a version number or last modification date, put it in the
-second line, right aligned.
-
-At the bottom of the help file, place a Vim modeline to set the 'textwidth'
-and 'tabstop' options and the 'filetype' to "help".  Never set a global option
-in such a modeline, that can have undesired consequences.
-
-
-TAGS
-
-To define a help tag, place the name between asterisks (*tag-name*).  The
-tag-name should be different from all the Vim help tag names and ideally
-should begin with the name of the Vim plugin.  The tag name is usually right
-aligned on a line.
-
-When referring to an existing help tag and to create a hot-link, place the
-name between two bars (|) eg. |help-writing|.
-
-When referring to a Vim command and to create a hot-link, place the
-name between two backticks, eg. inside `:filetype`.  You will see this is
-highlighted as a command, like a code block (see below).
-
-When referring to a Vim option in the help file, place the option name between
-two single quotes, eg. 'statusline'
-
-When referring to any other technical term, such as a filename or function
-parameter, surround it in backticks, eg. `~/.path/to/init.vim`.
-
-
-HIGHLIGHTING
-
-To define a column heading, use a tilde character at the end of the line.
-This will highlight the column heading in a different color.  E.g.
-
-Column heading~
-#^^^^^^^^^^^^^ markup.heading.header
-#             ^ punctuation.definition.keyword
-
-To separate sections in a help file, place a series of '=' characters in a
-line starting from the first column.  The section separator line is highlighted
-differently.
-
-To quote a block of ex-commands verbatim, place a greater than (>) character
-at the end of the line before the block and a less than (<) character as the
-first non-blank on a line following the block.  Any line starting in column 1
-also implicitly stops the block of ex-commands before it.  E.g. >
-    function Example_Func()
-	echo "Example"
-    endfunction
-<
-
-The following are highlighted differently in a Vim help file:
-  - a special key name expressed either in <> notation as in <PageDown>, or
-    as a Ctrl character as in CTRL-X
-  - anything between {braces}, e.g. {lhs} and {rhs}
-
-The word "Note", "Notes" and similar automagically receive distinctive
-highlighting.  So do these:
-	*Todo	something to do
-	*Error	something wrong
-
-You can find the details in $VIMRUNTIME/syntax/help.vim

            systemd reads the log level from this environment variable. This
            can be overridden with --log-level=.
 
-ENVIRONMENT VARIABLES
-       Various Git commands use the following environment variables:
-
-   The Git Repository
-       These environment variables apply to all core Git commands. Nb: it is
-       worth noting that they may be used/overridden by SCMS sitting above Git
-       so take care if using a foreign front-end.
-
-       GIT_INDEX_FILE
-#      ^^^^^^^^^^^^^^ support.constant.environment-variable
-           This environment allows the specification of an alternate index
-           file. If not specified, the default of $GIT_DIR/index is used.
-
-       GIT_INDEX_VERSION
-#      ^^^^^^^^^^^^^^^^^ support.constant.environment-variable
-           This environment variable allows the specification of an index
-           version for new repositories. It won’t affect existing index files.
-           By default index file version 2 or 3 is used. See git-update-
-           index(1) for more information.

-COMMANDS
-       This section only lists general commands. For input and output com‐
-       mands, refer to sway-input(5) and sway-output(5).
-
-       The following commands may only be used in the configuration file.

-
-Usage: bat [OPTIONS] [FILE]...
-       bat <COMMAND>
-
-Arguments:
-  [FILE]...
-          File(s) to print / concatenate. Use a dash ('-') or no argument at all to read from
-          standard input.
-
-Options:
-  -A, --show-all
-          Show non-printable characters like space, tab or newline. This option can also be used to
-          print binary files. Use '--tabs' to control the width of the tab-placeholders.
-
-      --nonprintable-notation <notation>
-          Set notation for non-printable characters.
-          
-          Possible values:
-            * unicode (␇, ␊, ␀, ..)
-            * caret   (^G, ^J, ^@, ..)
-
-  -p, --plain...
-          Only show plain style, no decorations. This is an alias for '--style=plain'. When '-p' is
-          used twice ('-pp'), it also disables automatic paging (alias for '--style=plain
-          --paging=never').
-
-  -l, --language <language>
-          Explicitly set the language for syntax highlighting. The language can be specified as a
-          name (like 'C++' or 'LaTeX') or possible file extension (like 'cpp', 'hpp' or 'md'). Use
-          '--list-languages' to show all supported language names and file extensions.
-
-  -H, --highlight-line <N:M>
-          Highlight the specified line ranges with a different background color For example:
-            '--highlight-line 40' highlights line 40
-            '--highlight-line 30:40' highlights lines 30 to 40
-            '--highlight-line :40' highlights lines 1 to 40
-            '--highlight-line 40:' highlights lines 40 to the end of the file
-            '--highlight-line 30:+10' highlights lines 30 to 40
-
-      --file-name <name>
-          Specify the name to display for a file. Useful when piping data to bat from STDIN when bat
-          does not otherwise know the filename. Note that the provided file name is also used for
-          syntax detection.
-
-  -d, --diff
-          Only show lines that have been added/removed/modified with respect to the Git index. Use
-          --diff-context=N to control how much context you want to see.
-
-      --diff-context <N>
-          Include N lines of context around added/removed/modified lines when using '--diff'.
-
-      --tabs <T>
-          Set the tab width to T spaces. Use a width of 0 to pass tabs through directly
-
-      --wrap <mode>
-          Specify the text-wrapping mode (*auto*, never, character). The '--terminal-width' option
-          can be used in addition to control the output width.
-
-  -S, --chop-long-lines
-          Truncate all lines longer than screen width. Alias for '--wrap=never'.
-
-      --terminal-width <width>
-          Explicitly set the width of the terminal instead of determining it automatically. If
-          prefixed with '+' or '-', the value will be treated as an offset to the actual terminal
-          width. See also: '--wrap'.
-
-  -n, --number
-          Only show line numbers, no other decorations. This is an alias for '--style=numbers'
-
-      --color <when>
-          Specify when to use colored output. The automatic mode only enables colors if an
-          interactive terminal is detected - colors are automatically disabled if the output goes to
-          a pipe.
-          Possible values: *auto*, never, always.
-
-      --italic-text <when>
-          Specify when to use ANSI sequences for italic text in the output. Possible values: always,
-          *never*.
-
-      --decorations <when>
-          Specify when to use the decorations that have been specified via '--style'. The automatic
-          mode only enables decorations if an interactive terminal is detected. Possible values:
-          *auto*, never, always.
-
-  -f, --force-colorization
-          Alias for '--decorations=always --color=always'. This is useful if the output of bat is
-          piped to another program, but you want to keep the colorization/decorations.
-
-      --paging <when>
-          Specify when to use the pager. To disable the pager, use --paging=never' or its
-          alias,'-P'. To disable the pager permanently, set BAT_PAGING to 'never'. To control which
-          pager is used, see the '--pager' option. Possible values: *auto*, never, always.
-
-      --pager <command>
-          Determine which pager is used. This option will override the PAGER and BAT_PAGER
-          environment variables. The default pager is 'less'. To control when the pager is used, see
-          the '--paging' option. Example: '--pager "less -RF"'.
-
-  -m, --map-syntax <glob:syntax>
-          Map a glob pattern to an existing syntax name. The glob pattern is matched on the full
-          path and the filename. For example, to highlight *.build files with the Python syntax, use
-          -m '*.build:Python'. To highlight files named '.myignore' with the Git Ignore syntax, use
-          -m '.myignore:Git Ignore'. Note that the right-hand side is the *name* of the syntax, not
-          a file extension.
-
-      --ignored-suffix <ignored-suffix>
-          Ignore extension. For example:
-            'bat --ignored-suffix ".dev" my_file.json.dev' will use JSON syntax, and ignore '.dev'
-
-      --theme <theme>
-          Set the theme for syntax highlighting. Use '--list-themes' to see all available themes. To
-          set a default theme, add the '--theme="..."' option to the configuration file or export
-          the BAT_THEME environment variable (e.g.: export BAT_THEME="...").
-
-      --list-themes
-          Display a list of supported themes for syntax highlighting.
-
-      --style <components>
-          Configure which elements (line numbers, file headers, grid borders, Git modifications, ..)
-          to display in addition to the file contents. The argument is a comma-separated list of
-          components to display (e.g. 'numbers,changes,grid') or a pre-defined style ('full'). To
-          set a default style, add the '--style=".."' option to the configuration file or export the
-          BAT_STYLE environment variable (e.g.: export BAT_STYLE="..").
-          
-          Possible values:
-          
-            * default: enables recommended style components (default).
-            * full: enables all available components.
-            * auto: same as 'default', unless the output is piped.
-            * plain: disables all available components.
-            * changes: show Git modification markers.
-            * header: alias for 'header-filename'.
-            * header-filename: show filenames before the content.
-            * header-filesize: show file sizes before the content.
-            * grid: vertical/horizontal lines to separate side bar
-                    and the header from the content.
-            * rule: horizontal lines to delimit files.
-            * numbers: show line numbers in the side bar.
-            * snip: draw separation lines between distinct line ranges.
-
-  -r, --line-range <N:M>
-          Only print the specified range of lines for each file. For example:
-            '--line-range 30:40' prints lines 30 to 40
-            '--line-range :40' prints lines 1 to 40
-            '--line-range 40:' prints lines 40 to the end of the file
-            '--line-range 40' only prints line 40
-            '--line-range 30:+10' prints lines 30 to 40
-
-  -L, --list-languages
-          Display a list of supported languages for syntax highlighting.
-
-  -u, --unbuffered
-          This option exists for POSIX-compliance reasons ('u' is for 'unbuffered'). The output is
-          always unbuffered - this option is simply ignored.
-
-      --diagnostic
-          Show diagnostic information for bug reports.
-
-      --acknowledgements
-          Show acknowledgements.
-
-  -h, --help
-          Print help (see a summary with '-h')
