Hi - Great to see this functionality coming. There is one feature of it that I would really like to see fixed, which is currently broken in setuptools/distribute - I'm sorry if this is the wrong forum for this note, but I wanted to add it to the discussion somewhere.

That feature is the "package_dir" argument to setup(). If the sources aren't in the root directory, the package doesn't function correctly with `python setup.py develop`

Here is a reference to an issue filed against distribute:

https://bitbucket.org/tarek/distribute/issue/177/setuppy-develop-doesnt-support-package_dir-arg-to

Is there any possibility of seeing this work correctly? A lot of packages use it, and for them, `develop` is currently broken.

Apologies if this feature is implemented and I missed it, but I see no reference to "package_dir" in the patch, so I would be (pleasantly) surprised if it was implemented. I would be happy to provide a testcase on request.
