Class: Console_CommandLine_Action_Callback

The result option array entry value is set to the return value of the callback defined in the option.

There are two steps to defining a callback option:

• define the option itself using the callback action
• write the callback; this is a function (or method) that takes five arguments, as described below.

 callable_func(
   $value,      // the value of the option
   $option_instance, // the option instance
   $result_instance, // the result instance
   $parser_instance, // the parser instance
   $params      // an array of params as specified in the option
 );
