=head1 NAME
DateTime::Format::Natural::Duration - Duration hooks and state handling
=head1 SYNOPSIS
Please see the DateTime::Format::Natural documentation.
=head1 DESCRIPTION
The C<DateTime::Format::Natural::Duration> class contains code to alter
tokens before parsing and to insert DateTime objects in the resulting
queue. Furthermore, there's code to save the state of the first failing
parse and restore it after the duration has been processed.
