wiki helper cgi script

I have a few wikis on my site, all using UseMod. The following Python script
can be shared by all my wikis, and it lets me put a link on the wiki that
generates an alphabetized list of all the wiki's pages with links to them.
It doesn't care what directory or subdirectory the wiki in is. I just put the
following in the wiki:

   [http://willware.net:8080/cgi-bin/pagelist.py List] of all pages

I'm running this on a Linux box with Apache. YMMV otherwise.

Bon appetit, Will Ware
