Subject Re: Using Gump to find configurations

This is great feedback, thanks. I kinda ran out of steam when it came to
cross referencing, and only skimmed statistics.

Yeah, I was messing around w/ modules not projects to keep the pages small.
Nobody has liked it (not sure even me). I think moving to projects would be

Basically, to update these things (1) edit the gump/output/ and
gump/output/ classes (2) edit the gump/documentation/
module (at the bottom).

If you know Java/Perl you can't handle this Python stuff. It is kinda fun,
so long as you don't have to do 8 hour builds to crap out on one line -- 
that is as painful. Thankfully we now have some simple unit tests (including
for stats and xref).

If you get itch/time to help, please do. Post questions/patches here.
