Testing/development tips
------------------------

To run tests under CPython, run::

    pip install pytest     # if you don't have pytest already
    pip install pycparser
    python setup.py build_ext -f -i
    pytest c/ testing/

If you run in another directory (either the tests or another program),
you should use the environment variable ``PYTHONPATH=/path`` to point
to the location that contains the ``_cffi_backend.so`` just compiled.
