"""Setuptools based setup script for Mathics.

For the easiest installation just type the following command (you'll probably
need root privileges):

    python setup.py install

This will install the library in the default location. For instructions on
how to customize the install procedure read the output of:

    python setup.py --help install

In addition, there are some other commands:

    python setup.py clean -> will clean all trash (*.pyc and stuff)

To get a full list of available commands, read the output of:

    python setup.py --help-commands

Or, if all else fails, feel free to write to the mathics users list at
mathics-users@googlegroups.com and ask for help.
