This Python module provides a wrapper for argparse with support for hierarchical
commands that can be bound to modules or classes.

Features that argh adds to argparse:

* mark a function as a CLI command and specify its arguments before the parser
is instantiated;
* nested commands made easy: no messing with subparsers (though they are of
course used under the hood);
* infer agrument type from the default value;
* infer command name from function name;
* add an alias root command help for the --help argument;
* enable passing unwrapped arguments to certain functions instead of a
argparse.Namespace object.

Argh is fully compatible with argparse. argh-agnostic and argh-aware code
can be mixed. Keep in mind that argh.dispatch does some extra
work that a custom dispatcher may not do.
