See "BUGS" for a list of BUGS.
   I have tested this on many large FORTRAN files and it works.
   However these files only use a narrom range of f77.

  f77_diagram only produces the ".dot" output.
  To actually graph the plots you'll need the "graphviz" suite
  of utilities, available from:
  
     http://www.research.att.com/sw/tools/graphviz/
  
  f77_diagram supports some flags for setting paper size and the like.
  I'd recommend reading the "dot" documentation for finer-tuning this.

Example run:

   ./f77_diagram -l -o prime.dot prime.f
   
      creates "prime.dot" at letter (8.5"x11") size
      
   dot -Tpng prime.dot -o prime.png
     
      creates a png file
      
   dot -Tps prime.dot -o prime.ps
    
      creates a postscript version, etc.
