DAG - A Program that Draws Graphs

[Carl Burch]

     I found an article titled "DAG - A Program that Draws Directed Graphs"
in Software Practice and Experience (Nov. 88).  It compiles its input
language into either PIC or Postscript.  It looks like just the thing
for our usual job of doing documentation or slides for data structures and
the like.
     Does anyone know if there's a copy floating around?  Has anyone tried
it out?
