Python API documentation generation tool

I tried running this command against
svn://orbtech.com/schevo/Schevo/trunk:

"SCHEVO_OPTIMIZE=0 epydoc --html -o
~/schevodoc-out/epydoc/html --name=Schevo
--docformat=restructuredtext --show-sourcecode schevo"

And got a traceback. I tried both --parse-only and
--introspect-only and got different tracebacks each time.

I started hunting down the bugs and took a "shotgun"
approach to produce the attached patch. Too many
different tracebacks I got along the way to post here.

When I run the epydoc tests, I get the same 5 failing
doctests no matter whether this patch is applied or
not, so I'll leave it to an epydoc expert to verify the
correctness of these changes.

Runs great with patch, see
http://schevo.org/epydoc/html for output.

I'd be glad to provide more detail as requested.
