Xthough, you can do anything you need to do here and exit the program.

Xfacility if the functrion is to return,' since main()'s getopt() will
Xstop processing switches if it runs into an unrecognized switch with an
Xargument.
X
XIf the function returns a non-zero value, then the value will be passed
XDIRECTLY to exit() with no further ado.  Thus, a non-zero value must be
