This is a scikit-image wheel builder using Matt Terry's scripts and
Python.or g pythons:

https://github.com/matthew-brett/scikit-image-wheels

It runs the tests before uploading, and the tests will be a little
tough to get passing - they have lots of dependencies - but the
general structure is a bit cleaner than I had first thought,
