*
* 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'.
