argparse - A command line arguments parsing library in C (compatible with C++).
This module is inspired by parse-options.c (git) and python's argparse module.
Arguments parsing is common task in cli program, but traditional getopt
libraries are not easy to use. This library provides high-level arguments
parsing solutions.

will figure
out how to parse those out of argc
and argv
, it also automatically
generates help and usage messages and issues errors when users give the
program invalid arguments.

There are basically two forms of options:

) and some alphanumeric characters.Short options may be bundled, e.g. -a -b

Options are case-sensitive.
Options and non-option arguments can clearly be separated using the --
option.
