Argparse seems repititive - help to refactor this code.

I recommend installing the argh package, which sets up decorators and
other routines to help you solve exactly this problem.
https://pypi.python.org/pypi/argh
You should be able to install using
pip install argh
if you have pip set up. The documentation is here. Note that the
argument syntax changed a little bit between 0.19 and 0.20, so be sure
you're reading the documentation for the latest version, 0.23.1 or later.
