This simply shows that the ``python`` option can specify another section to
find the ``executable``. (The ``python`` option defaults to looking in the
``buildout`` section.) We do this by creating a custom Python that will have
some initialization that we can look for.

initialization, and then the Python's initialization. We show this with a
custom Python.
