;;; Commentary:
;; This file implements links to MH-E messages from within Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
;;; Code:
(require 'org)
;; Customization variables
(defcustom org-mhe-search-all-folders nil
"Non-nil means the search for the mh-message may extend to all folders.
When non-nil, the search for a message will extend to all other
folders if it cannot be found in the folder given in the link.
Searching all folders may be slow with the default pick based
search but is very efficient with one of the other search engines
supported by MH-E."
