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