+ * If an option character is seen that is not listed in OPTSTRING,
+ * return '?' after printing an error message.  If you set `custom_opterr' to

+ *
+ * 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

+ * 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
