     * arguments without the leading reference to the running program.
     *
     * The second parameter is a string of allowed short options. Each of the
     * option letters can be followed by a colon ':' to specify that the option
     * requires an argument, or a double colon '::' to specify that the option
     * takes an optional argument.
     *
     * The third argument is an optional array of allowed long options. The
     * leading '--' should not be included in the option name. Options that
     * require an argument should be followed by '=', and options that take an
     * option argument should be followed by '=='.
     *
     * The return value is an array of two elements: the list of parsed
     * options and the list of non-option command-line arguments. Each entry in
     * the list of parsed options is a pair of elements - the first one
     * specifies the option, and the second one specifies the option argument,
     * if there was one.
     *
     * Long and short options can be mixed.
