- * The first parameter to this function should be the list of command-line
- * 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.
- *
- * Most of the semantics of this function are based on GNU getopt_long().
