docs.python.org should provide a distutils reference, and drop the  "Installing/Distributing Python Modules" guides in deference to the PUG.

to be clearer, the 2 "* Python Modules" guides have some good content, but I think it needs to be pushed into the distutils reference, not presented in a "guide" to installation and distribution.
 
and setuptools (as an extension of distutils) should provide a *complete* index of commands/options that covers everything

this index could just link to the distutils reference docs (in the case where setuptools hasn't modifed anything), if those sections were filled out sufficiently
