;; Version: 0.1057.104
;; Keywords: outlines, calendar

;;; Commentary:
;;
;; This file provides the import of events from Mac OS X 10.5 iCal.app
;; into the Emacs diary (it is not compatible with OS X < 10.5). The
;; function org-mac-iCal will import events in all checked iCal.app
;; calendars for the date range org-mac-iCal-range months, centered
;; around the current date.
;;
;; CAVEAT: This function is destructive; it will overwrite the current
;; contents of the Emacs diary.
;;
;; Installation: add (require 'org-mac-iCal) to your .emacs.
;;
;; If you view Emacs diary entries in org-agenda, the following hook
;; will ensure that all-day events are not orphaned below TODO items
;; and that any supplementary fields to events (e.g. Location) are
;; grouped with their parent event
;;
