Okay, I've made tox.ini the source for testing dependencies and now 
build the test extra from it in setup.py using ConfigParser.

It appears that the pip installation tox uses will only pick released 
packages, while easy_install picks beta releases. I use stuff in Mock 
0.8.0bx, how can I get that package to be used by tox?

Also, it looks like Tox does --no-deps when installing the package:

../bin/pip install 
--download-cache=/Users/chris/LocalGIT/testfixtures/.tox/_download -U 
--no-deps ../../../dist/testfixtures-2.3.3.tar.gz >5.log

Why would it do that?! I *really* want my packages' dependencies

Okay, done, and appears to work :-)

Ah, my bad, this is installed by buildout, as vritualenv is a dependency 
of tox :-)

Hmm, nope, I'll raise it with Enthought...
