Kaya sent me an example file which was very helpful. Thanks Kaya. I'm
attaching that file in case anyone else needs it. So, I figured that
out, and I'm moving on to the more challenging stuff. I need to make a
tree structure, just like the monodoc class listing. I only need one
level of nesting the items, if you understand what I mean.

+Group 1
  |--Element in group 1
  |--Another element
+Group 2
  |--Element in group 2

and so on...

Any pointers on this one?
I've already made a big progress and would like to finish what I've
Thanks again for your help.
