No problem, here's the cgi, and the templates.  The code is fairly  
explanatory.  I have a function, which takes a directory listing, and  
looks in the sub-directories for index.html files.  If an index page  
is found, it then returns the contents of <title>, along with the  
path of the index file.

My directory structure looks like:

Sites
  - cgi-bin
  - - libLibrary
  - BooksOnline
  - - albatross
  - - MySQL
  - - Python-Docs-2.4.2

I appreciate all the help, guys!
