Sorry Bob, but I just released 1.1 without this. I've been anxious to

ExampleGroup class, each of which is unique and has its own
description. Why don't you see if you can exploit that for your needs.
If not, go ahead and submit a patch to the tracker. Now that we've
gotten past the big hump of the 1.1 release, we should get back on
track of more frequent minor releases.
