- * Scan elements of ARGV 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 `custom_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 -1.
- * Then `custom_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 `custom_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 `custom_optarg'. Two colons mean an option that
- * wants an optional arg; if there is text in the current ARGV-element,
- * it is returned in `custom_optarg', otherwise `custom_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.
- *
- * Return the option character from OPTS just read. Return -1 when there are
- * no more options. For unrecognized options, or options missing arguments,
- * `custom_optopt' is set to the option letter, and '?' is returned.
- *
- * The OPTS string is a list of characters which are recognized option letters,
- * optionally followed by colons, specifying that that letter takes an
- * argument, to be placed in `custom_optarg'.
- *
- * If a letter in OPTS is followed by two colons, its argument is optional.
- * This behavior is specific to the GNU `getopt'.
- *
- * The argument `--' causes premature termination of argument scanning,
- * explicitly telling `getopt' that there are no more options. If OPTS begins
- * with `--', then non-option arguments are treated as arguments to the option
- * '\0'. This behavior is specific to the GNU `getopt'.
