Arg_parser is an argument parser that follows POSIX and GNU conventions for command line arguments. The C++ version is implemented as a C++ class, while the C version is implemented as a single struct plus associated functions. Both are simpler, easier to use, and safer that 'getopt_long'.

For maximum stability, Arg_parser is self-contained. It extracts all the information it needs from its arguments to avoid refering to them later. This avoids index-out-of-bounds errors.

Arg_parser does not modify its arguments, nor uses any global variables. So you may create more than one parser in your program if you need or want to.

The C++ version of Arg_parser can also parse options from configuration files.

To use Arg_parser in your own programs simply copy the files 'arg_parser.h' and 'arg_parser.cc' (or 'carg_parser.h' and 'carg_parser.c' for the C version) in your source tree. See also the file 'main.cc' ('cmain.c') for an example of use.
