@Carreau @jhamrick @ellisonbg : If you really want to have a setup.py alongside flit metadata, you can use this, and the setup.py will look like:

from flituptools import setup
setup()

I don't recommend doing this, and I don't intend to support it or use it myself, but it's simple enough and it works. Feel free to improve on it.
