// 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 `woptind' 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 `woptind' 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
// `wopterr' 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 `w.woptarg', otherwise `w.woptarg' 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.
//
// 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 long-named options.
