Motivation
----------

This project is a simplified version of Python subprocess control with
pipes and asynchronous support.  It is being developed to support
`tapedeck <http://github.com/zthompson47/tapedeck>`_,
a music streaming package which uses ffmpeg and other shell commands to
get music from various sources to various destinations.
