virtualenvwrapper and Python 3

I installed python 3.3.1 on ubuntu lucid and successfully created a virtualenv as below

    virtualenv envpy331 --python=/usr/local/bin/python3.3

this created a folder envpy331 on my home dir.

I also have virtualenvwrapper installed.But in the docs only 2.4-2.7 versions of python are supported..Has anyone tried to organize the python3 virtualenv ? If so, can you tell me how ?

The latest version of virtualenvwrapper is tested under Python3.2. Chances are good it will work with Python3.3 too.
