  We are having a problem printing grn files.  Some of these files
  contain spline curves (as opposed to just "curves") specified
  like the following:

  CURVE BSPLINE
  124.00 408.00
   .
   .
   .

  
  instead of just:

  CURVE
  124.00 408.00
   .
   .
   .


  The first problem is that our version of grn doesn't know how to read
  the CURVE BSPLINE.  The word "BSPLINE" gets read as some weird
  coordinates and added to the curve.  My first question is, does
  anyone know where I can get a version of grn that will know what to
  do with the BSPLINE curve? 

  The second problem is conjecture.  We are running the transcript 
  software (version 2.1), using psdit to convert from ditroff
  intermediate language to postscript.  Looking at the source to psdit,
  I noticed that the only curve drawing it supports is a "~" drawing
  function.  So if I had a grn that did the right thing with b-splines,
  would psdit then fail?  If so, where would I be able to get a 
  ditroff->postscript filter that would support it?  Is it hidden 
  somewhere in transcript that I just haven't seen?

  Thanks for any help.
