Hmm, missed that one.
I used to use it to extend Altsys Virtuoso's strokes and fills ---
had one which was an improvement of one written by Olav Martin Kvern
which would print the length of a line --- by contrast now one has to
either get a drawing tool w/ direct support for such (Canvas) or get
a plug-in (CADtools for InDesign).

As an example of that, Frank Siegert had a .ps program which would
reprogram a NeXT system to play a sound whenever a certain sequence
was typed ``batman'' I think it was.
