Yes, actually it's already in!

It seems to be working great for me.  Hope so for you as well, if not
we'll fix it.

I'll make the change.  I've had problems with the simple notation in
certain situations in the past but if it works fine here, great.
Didn't realize some php installations didn't include this.

Well it would be easy enough to do group=Main-*

I don't know that the subgroup variables would be created for each
item in the page list--as they are only created when Hg is run.  Or
are you saying there's a way to do something when a page is a new
group... That would do it exactly...  Yes, there must be as some
pagelists return nothing but a list of groups.  Perfect!  Thanks
Kathryn--that's the answer!
