/* verser globals */

/*
 * Dvirle was rewritten based on a program called "verser".
 * The original program was written by Janet Incerpi of Brown University
 * and was for the original version of TeX which also used a different kind
 * of font file.  It was modified at the University of Washington by
 * Richard Furuta (bringing it up to TeX82 and PXL files) and Carl Binding
 * (adding horizontal printing).  I then tore it to shreds and rebuilt
 * it; the new one is much faster (though less portable:  it has inline
 * assembly code in various critical routines).
 *
 * Chris Torek, 20 May 1984, University of Maryland CS/EE
 *
 * The program has since gone through much revision.  The details are
 * rather boring, but there is one important point:  The intermediate
 * file format has changed.
 *
 * Converted to dvirle by Spencer W. Thomas, April 1987, U of Utah CS.

/*
 * Version number.  Increment this iff the intermediate file format
 * makes an incompatible change.  This number may not be > 127.
