 Uses L<Module::Find> to find all classes under the database class' namespace,
 or uses the classes you select.  Then it loads the component (using L<use>), 
 and registers them (using B<register_class>);
 
+It is possible to comment out classes with a leading '#', but note that perl
+will think it's a mistake (trying to use a comment in a qw list) so you'll
+need to add "no warnings 'qw';" before your load_classes call.
