For the edification of pic fans, I have posted a pic program that lays out binary trees from one-line functional descriptions like this:node(leaf,node(leaf,leaf)) The program is a lovely example of the power of pic macros and blocks, unlike anything in the tutorial literature. Get it from www.cs.dartmouth.ed/~doug/tree.pic. Try it with groff -p -ms tree.pic.
Excellent stuff Doug - Damian
