[TIP] Using tox with py.test to test on python 2 and python 3

I'm trying to set up a tox for a project that is using py.test . 
My goal is to maintain a Python 2.6 source tree for the time being,
but start testing on python 3.2 now.

In the setup.py I'm using distributes use_2to3 flag to automatically
convert the sources to python3 at installation time, like this:

import sys
kw = {}
if sys.version_info >= (3,):
    kw['use_2to3'] = True
    name = "utilities",
    packages = ["utilities"]
    description = "Various utilities for measurement tasks",
    version = "0.1",

I am still not sure on the best way to organize the tests. I tried
adding them as a sub-package of the utilities package, which works,
but I would prefer not to install the test suite. My current tox.ini
looks like this:

envlist = py26,py32

commands=py.test []

commands=py.test []

Is there support for running 2to3 over a folder in tox? Or should I do
this manually by figuring out the necessary steps and add them to the
commands in testenv:py32 ?
