Help with copytree code

[Beech Rintoul]

This copytree code is from bsd.port.mk, and I've been asked to try and 
find a fix. This is very handy for installing a whole tree (like a 
web app) keeping everything intact. It wasn't designed to copy to a 
populated directory so it affects everything in that dir, not just 
what's being installed. We need to keep it's functionality, but a fix 
is more than I can come up with. So I thought I'd ask you code gurus 
to help. If this can be fixed many will thank you!

I attached it so it won't get line wrapped.

Thanks,

Beech
