""" MMA uses a number of application specific modules. These should
    be installed in a mma modules directory or in your python
    site-packages directory). MMA searches for the modules
    directory and pre-pends the first found to the python system list.

    If you end up with mma running (ie: it finds its modules), but
    can't find libraries you then probably have the modules installed
    in python-site and lib, include, etc. are NOT in one of the following
    locations (lib and include must be in the same directory).

    Note: it is quite possible with this method to have the modules
    somewhere in python-site (NOT supported by MMA's standard installs)
    and to have MMA's libraries in a different location (ie: /usr/share/mma).
