+
+=head2 DESCRIPTION
+
+Contains functions which are unique to insteon devices which have more than
+one group.  This includes, KeyPadLincs, RemoteLincs, FanLincs, Thermostats 
+(i2 versions).
+
+=head2 INHERITS
+
+Nothing.
+
+This package is meant to provide supplemental support and should only be added
+as a secondary inheritance to an object.

+package Insteon::MultigroupDevice;

+=item C<sync_all_links(audit_mode)>
+
+Syncs all links on the object, including all subgroups such as additional
+buttons.
+
+Paramter B<audit_mode> - Causes sync to walk through but not actually 
+send any commands to the devices.  Useful with the insteon:3 debug setting for 
+troubleshooting.
