regex 4 pga3

I'm surprised how easily I've slipped into wxWindows ... it's like MFC, but
a little more intuitive. Consequently, I've done a lot of work done on the
Query Builder doodad I'm building.

To progress, I need/want regular expressions ... I noticed there is a regex
library included with wxWindows (although there doesn't appear to be any
documentation for it). Does anybody have experience with this regex library?
Does anybody have a preference which one I link to? If not, I'm just going
to link to that one and give it whack.

Thanks,
Keith
