"""
Distutils installation script.

Three extended classes inspired by (shamelessly ripped from) gaupol:
InstallLib fixes the paths in paths.py, initially set for local execution.
InstallData compiles .mo files and installs them in locale/LC_MESSAGES.
Clean removes the translations, .pyc and .pyo files and some other things.
