module to parse @ARGV with a richer and more user-friendly API

 Getopt::ArgParse provides the following features:
 .
   - Generating usage messages
   - Storing parsed arg values in an object, which can be also used to
     load configuration values from files and therefore the ability for
     applications to combine configurations in a single interface
   - A more user-friendly interface to specify arguments, such as
     argument types, argument values split, etc.
   - Subcommand parsing, such svn <command>
   - Supporting both flag based named arguments and positional arguments
 .
 Getopt::ArgParse provides similar functionality to Python's argparse module.
