ya_getopt - Yet another getopt
==============================

What is ya_getopt.
------------------

Ya_getopt is a drop-in replacement of [GNU C library getopt](http://man7.org/linux/man-pages/man3/getopt.3.html).
`getopt()`, `getopt_long()` and `getopt_long_only()` are implemented excluding the following GNU extension features.

1. If *optstring* contains **W** followed by a semicolon, then **-W** **foo** is
   treated as the long option **--foo**.

2. \_\<PID>\_GNU\_nonoption\_argv\_flags\_

The license is 2-clause BSD-style license. You can use the Linux getopt compatible function
under Windows, Solaris and so on without having to worry about license issue.

Note for contributors
---------------------

Don't send me a patch if you have looked at GNU C library getopt source code.
That's because I made this with clean room design to avoid the influence of the GNU LGPL.

Please make a test script passed by the GNU C library getopt but not by ya_getopt instead.
