+ * Soft:        Vrrpd is an implementation of VRRPv2 as specified in rfc2338.
+ *              VRRP is a protocol which elect a master server on a LAN. If the
+ *              master fails, a backup server takes over.
+ *              The original implementation has been made by jerome etienne.
+ *
+ * Version:     $Id: vrrpd.h,v 0.7 2002/02/04 12:00:00 dhunter Exp $
+ *
+ * Author:      Jerome Etienne, <jetienne@arobas.net>
+ *
+ * Contributor: Alexandre Cassen, <acassen@linux-vs.org>
+ *
+ * Changes:
+ *              David Hunter : 2002/02/04 :
+ *               <+> Added orig_prio & delt_prio in vrrp_rt.
+ *              Alexandre Cassen : 2001/05/23 :
+ *               <+> Added IPSEC AH sequence number counter in vrrp_rt.
