   Note that xauth interprets certain transport values slightly
   different than in most other DECwindows Motif interfaces. xauth
   Transport Actions describes how xauth interprets each transport.

   INET            All entries in the X authority file whose
                   host address matches any of the IPv4 addresses
                   associated with the same TCP/IP host.
   INET6           All entries in the X authority file whose host
                   address matches any of the IPv4 or IPv6 addresses
                   associated the same TCP/IP host.
   TCPIP or TCP    All entries in the X authority file as if INET
                   or INET6 had been specified, depending on the
                   setting of DECW$IPV6_SUPPORT.
