     GETOPT(3C)		       UNIX System V		    GETOPT(3C)
     ...
	  extern int optind, opterr;
     ...
     DIAGNOSTICS
	  Getopt prints	an error message on stderr and returns a
	  question mark	(?) when it encounters an option letter	not
	  included in optstring.  This error message may be disabled
                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	  by setting opterr to a non-zero value.
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
     ...
Please, read the man page.  (Note too that getopt(3) NEVER generates Usage:
messages.)  This message would have been mailed except I am not sure
how to send mail to kos@ernie.Berkeley.EDU.
