-
- In addition to making sure no arguments are given, and
- implementing a --help option, this example will have a
- --version option, and will put the given documentation string
- and bug address in the --help output, as per GNU standards.
-
- The variable ARGP contains the argument parser specification;
- adding fields to this structure is the way most parameters are
- passed to argp_parse (the first three fields are usually used,
- but not in this small program). There are also two global
- variables that argp knows about defined here,
- ARGP_PROGRAM_VERSION and ARGP_PROGRAM_BUG_ADDRESS (they are
- global variables because they will almost always be constant
- for a given program, even if it uses different argument
- parsers for various tasks). */
