-/* Argp example #4 -- a program with somewhat more complicated options */
-
-/* This program uses the same features as example 3, but has more options,
- and somewhat more structure in the -help output. It also shows how you
- can `steal' the remainder of the input arguments past a certain point, for
- programs that accept a list of items. It also shows the special argp KEY
- value ARGP_KEY_NO_ARGS, which is only given if no non-option arguments
- were supplied to the program.
-
- For structuring the help output, two features are used, *headers* which
- are entries in the options vector with the first four fields being zero,
- and a two part documentation string (in the variable DOC), which allows
- documentation both before and after the options; the two parts of DOC are
- separated by a vertical-tab character ('\v', or '\013'). By convention,
- the documentation before the options is just a short string saying what
- the program does, and that afterwards is longer, describing the behavior
- in more detail. All documentation strings are automatically filled for
- output, although newlines may be included to force a line break at a
- particular point. All documenation strings are also passed to the
- `gettext' function, for possible translation into the current locale. */
