C{setup.py}. If you need compatibility functions for this code, duplicate them
here.

@var _EXTRA_OPTIONS: These are the actual package names and versions that will
    be used by C{extras_require}.  This is not passed to setup directly so that

@var _EXTRAS_REQUIRE: C{extras_require} is a dictionary of items that can be

    install the optional dev dependencies one would type::

pip install -e ".[dev]"
