;;
;; Here are the commands you can use:
;;
;; M-x `org-freemind-from-org-mode'
;; M-x `org-freemind-from-org-mode-node'
;; M-x `org-freemind-from-org-sparse-tree'
;;
;; M-x `org-freemind-to-org-mode'
;;
;; M-x `org-freemind-show'

;;; Change log:
;;
;; 2009-02-15: Added check for next level=current+1
;; 2009-02-21: Fixed bug in `org-freemind-to-org-mode'.
;; 2009-10-25: Added support for `org-odd-levels-only'.
;; Added y/n question before showing in FreeMind.
