"""
Enable running `pip-accel` as ``python -m pip_accel ...``.
This module provides a uniform (platform independent) syntax for invoking
`pip-accel`, that is to say the command line ``python -m pip_accel ...`` works
the same on Windows, Linux and Mac OS X.
This requires Python 2.7 or higher (it specifically doesn't work on Python
2.6). The way ``__main__`` modules work is documented under the documentation
of the `python -m`_ construct.
