|

*
|
|
* 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

|
|
* 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.
