A new release of libargp, version 20230708-2, is available in Cygwin. This
Cygwin-only update fixes a bug in the previous release, 20230708-1, that could
make libargp output the wrong bug report address, or return the wrong exit
status. I recommend that all users upgrade.

Argp is an interface for parsing unix-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.

The header file <argp.h> should be included to use argp.
