+;;; Commentary:
+;; This file is dumped with XEmacs.
+;; These are default settings for names of certain files and directories
+;; that Emacs needs to refer to from time to time.
+;; If these settings are not right, override them with `setq'
+;; in site-start.el.  Do not change this file.
+;;; Code:
+;Note: FSF's version is:
+;(defvar Info-default-directory-list
+;  (let ((start (list "/usr/local/lib/info/"
+;		      ;; This comes second so that, if it is the same
+;		      ;; as configure-info-directory (which is usually true)
+;		      ;; and Emacs has been installed (also usually true)
+;		      ;; then the list will end with two copies of this;
+;		      ;; which means that the last dir file Info-insert-dir
+;		      ;; finds will be the one in this directory.
+;		      "/usr/local/info/"))

+;They are searched in the order they are given in this list.
+;Therefore, the directory of Info files that come with Emacs
+;normally should come last (so that local files override standard ones).")
