> In
> org.apache.commons.cli.Option
> public method clone is implemented by creating a new instance through one of
> the class Constructors, and then assigning values as required through the
> setter methods.
> This means that any subclasses of the Option class will not return a true
> clone, but a new Option instance instead.
> A proper implementation of clone should use super.clone() to create a new
> instance, rather than calling the class constructor. This allows shallows
> clones to propogate correctly down to subclasses.
