This is a way to get python code documentation for Chimera.

In Chimera-IDLE (on linux or *nix):
{{{
#!py
import os
os.makedirs('/var/tmp/chimera-pydoc')
os.chdir('/var/tmp/chimera-pydoc')
sharepath = os.path.join(os.getenv('CHIMERA'),'share')
import pydoc
pydoc.writedocs(sharepath)
}}}

It creates a lot of .html files in /var/tmp/chimera-pydoc/.  The .html files contain links to the source .py files.  Firefox will open the /var/tmp/chimera-pydoc directory and generate an index of all the files.  The pydoc html is fairly well cross-linked.
