setup.py

#!/usr/bin/env python
"""Distutils based setup script for SymPy.

This uses Distutils (https://python.org/sigs/distutils-sig/) the standard
python mechanism for installing packages. Optionally, you can use
Setuptools (https://setuptools.readthedocs.io/en/latest/)
to automatically handle dependencies. For the easiest installation
just type the command (you'll probably need root privileges for that):

    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)
    python setup.py test  -> will run the complete test suite
    python setup.py bench -> will run the complete benchmark suite
    python setup.py audit -> will run pyflakes checker on source code

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 sympy list at
sympy@googlegroups.com and ask for help.
