Python subprocess interface
sh (previously [pbs](http://pypi.python.org/pypi/pbs)) is a full-fledged subprocess replacement for Python 2.6 - 3.2 that allows you to call any program as if it were a function:
`python from sh import ifconfig print ifconfig("eth0") `
sh is not a collection of system commands implemented in Python.
$> pip install sh
