+;;; Commentary:
+;;
+;; This file contains functionality to integrate screen and org-mode.
+;; When using org-mode, it is often useful to take tasks that have
+;; some command-line work associated with them, and associate them
+;; with a screen session.  Screen is used rather than a direct
+;; terminal to facilitate portability of the resulting session.
+;;
+;; To use screen in org, in your .emacs file, simply put this file in
+;; a directory in your load-path and write:
+;;
+;; (require 'org-screen)
+;;
+;; When have a task and want to start some command-line activity
+;; associated with that task, go to the end of your item and type:
+;;
+;; M-x org-screen
+;; 
+;; This will prompt you for a name of a screen session.  Type in a
+;; name and it will insert a link into your org file at your current
+;; location.
+;;
+;; When you want to visit the link, go to the link and type C-c C-o to
+;; open the link.
+;;
+;; You may want to get rid of the constant queries about whether you
+;; really want to execute lisp code.  Do so by adding to your .emacs:
+;;
+;; (setq org-confirm-elisp-link-function nil)
