This attribute means the option exists for the purpose of separating option description text in the usage output. Libraries may choose to make it settable so that the library can determine which command line option is the first one that pertains to the library.
If the “documentation
” attribute is present, then all other
attributes are disabled except settable
, call-proc
and
flag-code
. settable
must be and is only specified if
call-proc
, extract-code
or flag-code
has been specified.
When present, the descrip
attribute will be displayed only when the
--help
option has been specified. It will be displayed flush to the
left hand margin and may consist of one or more lines of text. The name of
the option will not be printed.
Documentation options are for clarifying the usage text and will not appear in generated man pages or in the generated invoking texinfo doc.
