+	    First cut at supporting DHCPv6. Support is pretty much
+	    there for the sort of things the existing v4 server does,
+	    including tags, options, static addresses and relay
+	    support. Missing is prefix delegation. This is lightly
+	    tested alpha code, it is NOT YET PRODUCTION READY. Test
