/* Argp example #2 -- a pretty minimal program using argp */

/* This program doesn't use any options or arguments, but uses argp to be
   compliant with the GNU standard command line format.

   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 becuase they will almost always be constant for a given
   program, even if it uses different argument parsers for various tasks).  */
