 plac is a simple wrapper over the python standard library `argparse <http://docs.python.org/2/library/argparse.html>`_, it hides most of its
 complexity by using a declarative interface: the argument parser is inferred
 rather than written down by imperatively. It is targetting especially unsophisticated

+`Cliff <https://cliff.readthedocs.org/en/latest>`_  is a framework for building command-line programs.
 It uses setuptools entry points to provide subcommands, output formatters, and other extensions. The framework
 is meant to be used to create multi-level commands such as subversion and git, where the main program handles
 some basic argument parsing and then invokes a sub-command to do the work.
