To enable reading the Gnus manual, you could say something like:
+ (require 'info)
(setq Info-default-directory-list
(cons "~/gnus-5.6.53/texi" Info-default-directory-list))
+or
+
+ (require 'info)
+ (setq Info-directory-list
+ (cons "~/gnus-5.6.53/texi" Info-directory-list))
+
+depending on which version of Emacs or XEmacs you're using.
+
Note that Gnus and GNUS can't coexist in a single Emacs. They both use
the same function and variable names. If you have been running GNUS
in your Emacs, you should probably exit that Emacs and start a new one
