  26 ;;; Commentary:
  27 ;;
  28 ;; This file contains functionality to integrate screen and org-mode.
  29 ;; When using org-mode, it is often useful to take tasks that have
  30 ;; some command-line work associated with them, and associate them
  31 ;; with a screen session.  Screen is used rather than a direct
  32 ;; terminal to facilitate portability of the resulting session.
  33 ;;
  34 ;; To use screen in org, in your .emacs file, simply put this file in
  35 ;; a directory in your load-path and write:
  36 ;;
  37 ;; (require 'org-screen)
  38 ;;
  39 ;; When have a task and want to start some command-line activity
  40 ;; associated with that task, go to the end of your item and type:
  41 ;;
  42 ;; M-x org-screen
  43 ;;
  44 ;; This will prompt you for a name of a screen session.  Type in a
  45 ;; name and it will insert a link into your org file at your current
  46 ;; location.
  47 ;;
  48 ;; When you want to visit the link, go to the link and type C-c C-o to
  49 ;; open the link.
  50 ;;
  51 ;; You may want to get rid of the constant queries about whether you
  52 ;; really want to execute lisp code.  Do so by adding to your .emacs:
  53 ;;
