tox require a virtualenv installed to run correctly. Since I sort of hate virtualenv I've created this recipe to run tox with buildout.

Add this to your buildout:

[tox]
recipe = gp.recipe.tox

This will install a virtualenv with tox installed in parts/tox/

It's recommended to add this to your `~/.buildout/default.cfg`:

[buildout]
tox-install-dir = /home/gawel/.buildout/tox

This will install tox's virtualenv once for all your buildouts. You'll get a bin/tox binary to run tests
