  Customizable setter for modifying the value of an option or positional parameter. When an option or positional parameter is matched on the command line, its setter is invoked to capture the value. For example, an option can be bound to a field or a method, and when the option is matched on the command line, the field's value is set or the method is invoked with the option parameter value.
