Is it possible to deliver different source distributions for different Python versions?

Yep. I looked there first and from that thought that I could 
distribute "wheels" -- a 2.7 wheel, a 3.3 wheel, and a 3.4 wheel.
But the latest setup.py (version 15.0) doesn't build wheels anymore.
It does build binary distributions, but they are tied more to a
particular version of a particular OS rather than to a particular
version of Python.

So, anyway, I think parts of that documentation site are out of
date. And I didn't see anything that let me do what I wanted.
