Check out the punidraw tutorial in iv/src/papers/punidraw.ps.Z.  If
you'd like information on Unidraw beyond the man pages, you might
check out the article that appeared in the July 1990 issue of ACM
Transactions on Information Systems, titled "Unidraw: A Framework for
Building Domain-Specific Graphical Editors."

For more detail, you can order a copy of my thesis for a nominal cost
by sending mail to Naomi Schulman (schulman@shasta.stanford.edu).  Ask
for a copy of CSL-TR-90-427, titled "Generalized Graphical Object
Editing".  You can ftp the code for some of the example programs
described therein from interviews.stanford.edu in
pub/contrib/{drawing,schem}.tar.Z.
