    This setup.py script uses the setuptools 'setup_requires' feature because
    this is required by the cffi package to compile extension modules. The
    purpose of ``keywords_with_side_effects()`` is to avoid triggering the cffi
    build process as a result of setup.py invocations that don't need the cffi
    module to be built (setup.py serves the dual purpose of exposing package
    metadata).

    All of the options listed by ``python setup.py --help`` that print
    information should be recognized here. The commands ``clean``,
    ``egg_info``, ``register``, ``sdist`` and ``upload`` are also recognized.
    Any combination of these options and commands is also supported.

    also the discussion in `pip issue #25`_).
