  25 ;;; Commentary:
  26 ;; This file implements links to Apple Mail.app messages from within Org-mode.
  27 ;; Org-mode does not load this module by default - if you would actually like
  28 ;; this to happen then configure the variable `org-modules'.
  29
  30 ;; If you would like to create links to all flagged messages in an
  31 ;; Apple Mail.app account, please customize the variable
  32 ;; `org-mac-mail-account' and then call one of the following functions:
  33
  34 ;; (org-mac-message-insert-selected) copies a formatted list of links to
  35 ;; the kill ring.
  36
  37 ;; (org-mac-message-insert-selected) inserts at point links to any
  38 ;; messages selected in Mail.app.
  39
  40 ;; (org-mac-message-insert-flagged) searches within an org-mode buffer
  41 ;; for a specific heading, creating it if it doesn't exist.  Any
  42 ;; message:// links within the first level of the heading are deleted
  43 ;; and replaced with links to flagged messages.
