org-mode - markdown backend -- Emacs 24.3.1

A little reminder of something I failed to do before. Org-mode has optional export backends, some are loaded by default:

(message "%S" org-export-backends)
;; "(ascii html icalendar latex)"

(add-to-list 'org-export-backends 'md)

(message "%S" org-export-backends)
;; "(md ascii html icalendar latex)"

Now in an org-mode buffer, `C-c C-e` (org-export-dispatch) will have a markdown entry accessible through `m`.

ps: done on GNU Emacs 24.3.1 (i686-pc-linux-gnu, GTK+ Version 3.8.2) of 2013-08-07 on -mnt-storage-buildroots-staging-i686-eric; archlinux
