+B<CAVEAT> - if your Offline model overrides L<Class::DBI> methods, these methods
+will B<not> be overridden when called from the Maypole application, because the
+Maypole model provides an alternative path to L<Class::DBI> which is searched
+first. The solution is to place such methods in a separate package, e.g.
+C<OfflineBeer::CDBI>. Place this B<first> in the C<@ISA> of both
+C<BeerDB2::Maypole::Model> and C<OfflineBeer>. Note that C<OfflineBeer::CDBI>
+does not itself need to inherit from L<Class::DBI>.

 Methods defined in the Maypole model base class (C<BeerDB2::Maypole::Model>),
 override methods in the individual Offline table classes, and in the Offline
 model base class (C<Offline>).
