libargp and libargp-devel 20110921-3 are now available in Cygwin. This is a
Cygwin-only update, that separates the libargp package into two: 

* libargp: just the loadable DLL
* libargp-devel: header files for developers to use in building
applications with libargp.

Argp is an interface for parsing unix-style argument vectors. Argp provides
features unavailable in the more commonly used getopt interface, including
automatically producing output in response to the '--help' and '--version'
options.  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.
