;;; Commentary:
;; This file implements links to Apple Mail messages from within Org-mode.
;; Org-mode does not load this module by default - if you would actually like
;; this to happen then configure the variable `org-modules'.
;; If you would like to create links to all flagged messages in an
;; Apple Mail account, please customize the variable
;; org-mac-mail-account and then call one of the following functions:
;; (org-mac-create-flagged-mail) copies a formatted list of links to
;; the kill ring.
;; (org-mac-insert-flagged-mail) searches within an org-mode buffer
;; for a specific heading, creating it if it doesn't exist. Any
;; message:// links within the first level of the heading are deleted
;; and replaced with links to flagged messages.
;; If you have Growl installed and would like more visual feedback
;; whilst AppleScript searches for messages, please uncomment lines
;; 125 to 130.
