Good point. I think I learned an important point going through that
upgrade mess though: uninstall/reinstall is safer than upgrade.

Fair enough. Can I suggest that it have a --version option (since it
is traditional)?

Okay I've just tried that and that's definitely the way I want to use it.

So basically:
$ python setup.py bdist_wheel  # Makes wheels
    and
$ pip install foo.whl  # Installs wheels

If someone wants to import the bdist_wheel command and use it outside
of setuptools setup() (in the way that numpy does) where should they
import it from? I'm thinking of something like this:
https://github.com/numpy/numpy/blob/master/numpy/distutils/command/bdist_rpm.py

Is the following appropriate?

from wheel.bdist_wheel import bdist_wheel

class mybdist_wheel(bdist_wheel):
     ...

(the wheel API docs don't describe using bdist_wheel from Python code.)
