Getopt::ArgParse - Parsing command line arguments with a richer and
more user-friendly API interface, similar to python's argpare but with
perlish extras.
In particular, the modules 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 optional arguments and positional arguments
