Hm. What I am actually after is to "bless" an existing directory – source files and all – with a virtualenv (or pyvenv). I am not interested in the command deleting anything from anywhere, why thank you.

Workflow:

    $ git clone git@github.com:stefanholek/foo
    $ cd foo
    $ virtualenv .
    $ ./bin/python setup.py develop
    $ ./bin/python setup.py -q test

This is how I use virtualenv at the moment and I'd rather not lose that ability. Thanks.
