Argp is an interface for parsing GNU-style argument vectors.
Argp provides features unavailable in the more commonly used getopt
interface. These features include automatically producing output in
response to the --help and --version options, as described in the GNU
coding standards. Using argp makes it less likely that programmers will
neglect to implement these additional options or keep them up to date.
Argp also provides the ability to merge several independently defined
option parsers into one, mediating conflicts between them and making the
result appear seamless. A library can export an argp option parser that
user programs might employ in conjunction with their own option parsers,
resulting in less work for the user programs. Some programs may use only
argument parsers exported by libraries, thereby achieving consistent and
efficient option-parsing for abstractions implemented by the libraries.
