Gnus 5.8.x requires an emacs version that is greater than or equal to
   Emacs 20.x or XEmacs 20.x.
   
   Prior to Gnus 5.2, at least GNU Emacs 19.28, or XEmacs 19.12 was
   recommended. GNU Emacs 19.25 has been reported to work under certain
   circumstances, but it doesn't officially work on it. 19.27 has also
   been reported to work.
   
   Because of Gnus 5.2's use of Common Lisp features present only in
   late-model emacsen, it will only work with Emacs 19.30 or later, and
   XEmacs 19.13 or later.
   
   Emacs 20.2 has many show-stopping bugs. If you are using Emacs 20.2,
   upgrade to 20.3.
   
   Gnus 5.4 requires emacsen at least as recent as Emacs 19.33 or XEmacs
   19.14.
   
   Gnus has been reported to work under VMS, OS/2, and Microsoft Windows
   NT 3.51, as well as Unix.
   
   OS/2 requires
(setq gnus-score-file-suffix "score")
(setq gnus-adaptive-file-suffix "adapt")

   in the user's .gnus.

   [For Microsoft Windows NT] Be sure to grab the nttcp.exe file needed
   to perform the winsock communication and configure emacs to use it
   instead of the default tcp. You will also need to put
(setq tcp-program-name "nttcp")

   in your _emacs file.

   Actually, any TCP program will work. I have tcp.exe from the people
   who are doing win32 ports of Gnu software. I found it at
   <URL:ftp://microlib.cc.utexas.edu/microlib/nt/gnu/>. Be
   warned that this is a large (7mb) archive of all sorts of stuff,
   including (for some reason) all the e-lisp files you will ever want. I
   just downloaded it and extracted the functions I wanted.

   With the release of GNU Emacs 19.31, Microsoft Windows '95 & NT users
   no longer need nttcp.exe as Emacs now has open-network-stream built
   in.
