+   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

+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.
