This class is of interest to people writing Pod formatters based on Pod::Simple. It is useful for seeing exactly what events you get out of some Pod that you feed in. This is a subclass of L and inherits all its methods. =head1 SEE ALSO L L =head1 SUPPORT Questions or discussion about POD and Pod::Simple should be sent to the pod-people@perl.org mail list.
