This module is based on a rox module (LGPL):
http://cvs.sourceforge.net/viewcvs.py/rox/ROX-Lib2/python/rox/basedir.py?rev=1.9&view=log
The freedesktop.org Base Directory specification provides a way for
applications to locate shared data and configuration:
http://standards.freedesktop.org/basedir-spec/
(based on version 0.6)
This module can be used to load and save from and to these directories.
Typical usage:
from rox import basedir
for dir in basedir.load_config_paths('mydomain.org', 'MyProg', 'Options'):
print "Load settings from", dir
dir = basedir.save_config_path('mydomain.org', 'MyProg')

This module is based on a rox module (LGPL):
http://cvs.sourceforge.net/viewcvs.py/rox/ROX-Lib2/python/rox/mime.py?rev=1.21&view=log
This module provides access to the shared MIME database.
types is a dictionary of all known MIME types, indexed by the type name, e.g.
types['application/x-python']
Applications can install information about MIME types by storing an
XML file as <MIME>/packages/<application>.xml and running the
update-mime-database command, which is provided by the freedesktop.org
shared mime database package.
See http://www.freedesktop.org/standards/shared-mime-info-spec/ for
