Around the time of V3, Dr. Depalma wrote a superb OSRI reference
manual. Rumaging around the attic recently we found a backup of
Don's full documentation directory, so maybe we could get the book
back in print. Anybody out there want to write a set of Nroff
macros to generate HTML? Many, many glory points here.
