Command line interface tools are the new web framework. In addition to the
Python standard library's getopt, optparse and argparse there is a bewildering
array of packages available on the Python Packaging Index. Packages like Click,
Cliff, Docopt, Invoke all provide different mechanics for creating command line
applications. When all you want to do is expose a command line and get back to
creating functionality, it’s hard to know which alternative to reach for.

This presentation will have two parts, the first half will be a brief survey
of popular modules. Strengths, weaknesses and design philosophies will be
compared by creating command line processing for the same example program.
