Integrate docs of site-packages with Python doc index?

[Christoph Zwerschke]

I just thought it would be nice to have a standardized place to put the 
accompanying documentation for Python site packages, and something like 
a hook to register documentation so that all installed site packages can 
install links to their documentation in the Python Documentation Index.

Are there already any thoughts or standards on how to integrate/append 
documentation of later installed site packages to the standard Python 
documentation index, in order to get a complete hypertext documentation 
of all the installed Python modules?
