-   If the caller did not specify anything,

-
-   REQUIRE_ORDER means don't recognize them as options;
-   stop option processing when the first non-option is seen.
-   This is what Unix does.
-   This mode of operation is selected by either setting the environment
-   variable POSIXLY_CORRECT, or using `+' as the first character
-   of the list of option characters.
-
-   PERMUTE is the default.  We permute the contents of ARGV as we scan,
-   so that eventually all the non-options are at the end.  This allows options
-   to be given in any order, even with programs that were not written to
-   expect this.
-
-   RETURN_IN_ORDER is an option available to programs that were written
-   to expect options and other ARGV-elements in any order and that care about
-   the ordering of the two.  We describe each non-option ARGV-element
-   as if it were the argument of an option with character code 1.
-   Using `-' as the first character of the list of option characters
-   selects this mode of operation.
-
-   The special argument `--' forces an end of option-scanning regardless
-   of the value of `ordering'.  In the case of RETURN_IN_ORDER, only
-   `--' can cause `getopt' to return EOF with `optind' != ARGC.  */

-/* Scan elements of ARGV (whose length is ARGC) for option characters
-   given in OPTSTRING.
-
-   If an element of ARGV starts with '-', and is not exactly "-" or "--",
-   then it is an option element.  The characters of this element
-   (aside from the initial '-') are option characters.  If `getopt'
-   is called repeatedly, it returns successively each of the option characters
-   from each of the option elements.
-
-   If `getopt' finds another option character, it returns that character,
-   updating `optind' and `nextchar' so that the next call to `getopt' can
-   resume the scan with the following option character or ARGV-element.
-
-   If there are no more option characters, `getopt' returns `EOF'.
-   Then `optind' is the index in ARGV of the first ARGV-element
-   that is not an option.  (The ARGV-elements have been permuted
-   so that those that are not options now come last.)
-
-   OPTSTRING is a string containing the legitimate option characters.
-   If an option character is seen that is not listed in OPTSTRING,
-   return '?' after printing an error message.  If you set `opterr' to
-   zero, the error message is suppressed but we still return '?'.
-
-   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
-   so the following text in the same ARGV-element, or the text of the following
-   ARGV-element, is returned in `optarg'.  Two colons mean an option that
-   wants an optional arg; if there is text in the current ARGV-element,
-   it is returned in `optarg', otherwise `optarg' is set to zero.
-
-   If OPTSTRING starts with `-' or `+', it requests different methods of
-   handling the non-option ARGV-elements.
-   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
-   Long-named options begin with `--' instead of `-'.
-   Their names may be abbreviated as long as the abbreviation is unique
-   or is an exact match for some defined option.  If they have an
-   argument, it follows the option name in the same ARGV-element, separated
-   from the option name by a `=', or else the in next ARGV-element.
-   When `getopt' finds a long-named option, it returns 0 if that option's
-   `flag' field is nonzero, the value of the option's `val' field
-   if the `flag' field is zero.
-
-   The elements of ARGV aren't really const, because we permute them.
-   But we pretend they're const in the prototype to be compatible
-   with other systems.
-
-   LONGOPTS is a vector of `struct option' terminated by an
-   element containing a name which is zero.
-
-   LONGIND returns the index in LONGOPT of the long-named option found.
-   It is only valid when a long-named option has been found by the most
-   recent call.
-
-   If LONG_ONLY is nonzero, '-' as well as '--' can introduce

-   required_argument	(or 1) if the option requires an argument,
-   optional_argument 	(or 2) if the option takes an optional 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'
