-   System-system differences for TCP include files and macros.  This
-   file includes for each system the files necessary for network and
-   file I/O.  It should be used in conjunction with HTUtils.h to help
-   ensure portability across as many platforms and flavors of platforms
-   as possible.

-VAX/VMS
-
-   Under VMS, there are many versions of TCP-IP. Define one if you do
-   not use Digital's UCX product:
-
-  UCX                     DEC's "Ultrix connection" (default)
-  CMU_TCP                 Available via FTP from sacusr.mp.usbr.gov
-  SOCKETSHR               Eckhart Meyer's interface to NETLIB
-  WIN_TCP                 From Wollongong, now GEC software.
-  MULTINET                From SRI, became TGV, then Cisco.
-  DECNET                  Cern's TCP socket emulation over DECnet
-  TCPIP_SERVICES          TCP/IP Services (newer than UCX)
-
-   WIN_TCP, MULTINET and DECNET do not interfere with the
-   unix i/o library, and so they need special calls to read, write and
-   close sockets.  In these cases the socket number is a VMS channel
-   number, so we make the @@@ HORRIBLE @@@ assumption that a channel
-   number will be greater than 10 but a unix file descriptor less than
-   10.  It works.
