+When this mode is enabled, Emacs periodically saves each visited
+file in a separate file called the \"auto-save file\". This is a
+safety measure to prevent you from losing more than a limited
+amount of work if the system crashes.
+
+Auto-saving does not alter the file you actually use: the visited
+file is changed only when you request saving it explicitly (such
+as with \\[save-buffer]). If you want to save visited files
+automatically, use \\[auto-save-visited-mode]).
