+
+ 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). */
