I want to do some development on `distlib`, and in the process run the code via `virtualenv` which has distlib as a dependency.
That is, not run the process inside a virtualenv, but run virtualenv's code using a custom dependency. What are the steps I need to go through to achieve this? It seems to me that normal package management (`pip`) is not possible here. -- https://mail.python.org/mailman/listinfo/python-list
