* 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.

* 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.
