  28  *  quit  --  print message and exit
  29  *
  30  *  Usage:  quit (status,format [,arg]...);
  31  *      int status;
  32  *      (... format and arg[s] make up a printf-arglist)
  33  *
  34  *  Quit is a way to easily print an arbitrary message and exit.
  35  *  It is most useful for error exits from a program:
  36  *      if (open (...) < 0) then quit (1,"Can't open...",file);
