+;; 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
+;;
+;; (add-hook 'org-agenda-cleanup-fancy-diary-hook
+;; (lambda ()
+;; (goto-char (point-min))
