Great!

I'm just having a little trouble finding my way around the library. I was
stuck on looking for a replace algorithm variant to do what I needed. I need
to spend an evening studying the doc's I see.

One suggestion I have is to add to the Quick Reference table, the req'd
header. This would help newbies(me) get up and running faster.

Thanks, Jeff
