+define Package/6relayd/description
+ 6relayd is an IPv6-tool that relays IPv6-management protocols like router
+ discovery, neighbor discovery and DHCPv6 so that clients on routed (non-
+ bridged) interfaces can use the public address prefix, DHCPv6 and DNS-service
+ of a master interface. This is useful to avoid NAT in chained IPv6-routers.
