So if/when we accept the proposal in this thread, I'm thinking we should make a bunch of changes at once:- always use setuptools (this is a new dependency)- error on ``python setup.py install``
- error on ``python setup.py clean`` (saying "use `git clean -xdf` (or -Xdf ...) instead")- change ``python setup.py --help`` to first show numpy-specific stuff before setuptools help info- update all our install docs
And when "pip upgrade" is released (should be soon, see https://github.com/pypa/pip/pull/3194), officially change our mind and recommend the use of install_requires/setup_requires to packages depending on numpy.
