-                     The metaclass will add a class attribute for each value in

-                     of ``enum_param`` and on the values of ``return_name``. If
-                     ``return_name`` is ``True``, then the value of the new attribute is
-                     the name of that attribute; otherwise, if ``enum_param`` is a ``list``
-                     or a ``tuple``, the value will be the index of that param in
-                     ``enum_param``, optionally offset by ``start``, otherwise, it will
-                     be assumed that ``enum_param`` implementa a dict-like inteface and
-                     the value will be ``enum_param[attr_name]``.
-        :return_name: If ``True``, the enum values will the names of enum attributes. If
-                      ``False``, the default, the values will depend on the type of
-                      ``enum_param`` (see above).
-        :start: If ``enum_param`` is a list or a tuple, and ``return_name`` is ``False``,
-                this specifies an "offset" that will be added to the index of the attribute
-                within ``enum_param`` to form the value.
