Gee thanks, Rick. I wonder: how many "What's OAK? Can you give
me a poniter?" replies you got.
Folks: this list has lots of readers these days. And it's archived.
I like to go back through the archive, and it's nice when folks include
URL pointers to the resources they mention.
The poster usually has a URL farily handy -- it takes a minute or
two to dig it up, but you save yourself all the time of writing
those "What is OAK?" messages. I speak from experience.
