+;; A portion of this code is based on org-mw.el by Bastien Guerry.
+;;
+;;; Commentary:
+;;
+;; org-mm.el lets you convert Org files to MoinMoin files using
+;; the org-export.el experimental engine.
+;;
+;; Put this file into your load-path and the following into your ~/.emacs:
+;; (require 'org-mm)
+;;
+;; You also need to fetch Org's git repository and add the EXPERIMENTAL/
+;; directory in your load path.
+;;
+;; Fetch Org's git repository:
+;;
+;; ~$ cd ~/install/git/
+;; ~$ git clone git://repo.or.cz/org-mode.git
+;;
+;; Put this in your .emacs.el:
+;;
+;; (add-to-list 'load-path "~/install/git/org-mode/EXPERIMENTAL/")
+;;
+;; Export Org files to MoinMoin: M-x org-mm-export RET
+;;
+;;; Todo:
+;;
+;; - handle radio links
+;; - support caption and attributes in tables
+;; - better handline of source code and examples
+;; - handle inline HTML
+;;
+;;; Code:
