Yeah, that is kind of a problem with this module. It basically gives you 
the look and feel of Google's next/prev/jumpto bar at the bottom w/o the 
graphics. Now that I think about it, it wouldn't be too hard to add the 
ability to insert your own markup for a more custom look. For me, the 
benefits of having it encapsulated as a module are that it captures a 
simple technique for paging results (courtesy of Sam Tregar) and makes it 
easy to drop-in a solution for a common problem.

Thanks for the examples. If I'm reading your code correctly, this part is 
readily handled by my template. HTML::Pager handles splitting the data, 
returning the relevant records, building the navigation bar, and marking 
the current position. Perhaps I'm not understanding the message threading 
component which is admittedly more than the Pager is meant to handle.

So what it looks like you're doing here is going to create a bar that 
looks like the following (if there were 6 slices of returned data):
	1|2|3|4|5|6

Is that correct?

I've sent a copy to you directly to keep from flooding the list. If anyone 
else wants a copy let me know.
