 .SH USING JGRAPH TO DRAW PICTURES
 As hypercube.jgr and alb.jgr show, jgraph can be used as a postscript
 preprocessor to make drawings.  There are two advantages

 The first is that with jgraph, you know exactly where strings, lines,
 boxes, etc, will end up, because you plot them explicitly.  The second
 advantage is that for iterative drawings, with lots of patters, you
