Description:  Berkeley YACC

[ byacc is "Berkeley YACC", written by the same person who originally did
  "bison".  byacc is smaller, simpler, and faster than bison; it also
  generates smaller and faster parsers than bison.  It is the standard
  "yacc" distributed with BSD/386 and other Net-2 descendents as well as
  4.4BSD.  Needless to say, it contains no AT&T/USL code.  It is completely
  compatible with AT&T Yacc's documentation, though it does not neccessarily
  implement any UNdocumented features of AT&T Yacc.

  I made a small patch, with permission from the author; see CSU.diffs.  
  This patch is already applied; I included it only for reference.  It fixes
  a small bit of lint that ANSI/Posix cares about that older systems didn't.

  This is another piece of the 4.4BSD release which is being released here
  since it isn't covered by the U C Regents license (it wasn't done at or
  funded through CSRG, but is rather a contribution to BSD from outside UCB).
  If you must know, I happened to see it while grabbing "db-1.6" from UCB,
  and Keith Bostic said "sure, go ahead and post them both."
