+;;; Commentary:
+
+;; This file implements links to Info nodes from within Org-mode.
+;; Org-mode loads this module by default - if this is not what you want,
+;; configure the variable `org-modules'.
+
+;;; Code:
+
+(require 'org)
+
+;; Declare external functions and variables
+
+(declare-function Info-find-node "info" (filename nodename
+                                                 &optional no-going-back))
+(defvar Info-current-file)
+(defvar Info-current-node)
+
+;; Install the link type
+(org-add-link-type "info" 'org-info-open)
+(add-hook 'org-store-link-functions 'org-info-store-link)
+
+;; Implementation
+(defun org-info-store-link ()
+  "Store a link to an Info file and node."
+  "Store a link to an INFO folder or message."
+  (when (eq major-mode 'Info-mode)
+    (let (link desc)
+      (setq link (org-make-link "info:"

+      (setq desc (concat (file-name-nondirectory Info-current-file)
+                        ":" Info-current-node))
