-   required_argument	(or 1) if the option requires an argument,

-
-   If the field `flag' is not NULL, it points to a variable that is set
-   to the value given in the field `val' when the option is found, but
-   left unchanged if the option is not found.
-
-   To have a long-named option do something other than set an `int' to
-   a compiled-in constant, such as set a value from `optarg', set the
-   option's `flag' field to zero and its `val' field to a nonzero
-   value (the equivalent single-letter option character, if there is
-   one).  For long options that have a zero `flag' field, `getopt'

-   missing arguments, `optopt' is set to the option letter, and '?' is

-   The OPTS string is a list of characters which are recognized option
