The branch that checkin landed on is the one where I am trying to make
CMF trunk distributable as an egg.  Products which want to be
distributed as eggs need to avoid using __file__ directly, and instead
rely on the 'pkg_resource' APIs supplied with Phillip Eby's setuptools
(this makes them "zip_safe").

CMF isn't quite there yet:

  - Some of the tests play with __file__ in ways that are painful
    to reproduce, and I haven't gotten there yet.

  - The GenericSetup profile mechanism doesn't yet grok eggified
    products.

OTOH, the skins mechanism (on that branch) now works beautifully from
an eggified CMF.

Tres.
