"""
This library is a set of compatibilty access shims to the ``pip`` internal API.
It provides compatibility with pip versions 8.0 through the current release. The
shims are provided using a lazy import strategy by hacking a module by overloading
a class instance's ``getattr`` method. This library exists due to my constant
writing of the same set of import shims.
