+;;; Commentary:
+;;
+;; This code allows you to grab either the current selected items, or
+;; the frontmost url in various mac appliations, and insert them as
+;; hyperlinks into the current org-mode document at point.
+;;
+;; This code is heavily based on, and indeed requires,
+;; org-mac-message.el written by John Weigley and Christopher
+;; Suckling.
+;;
+;; Detailed comments for each application interface are inlined with
+;; the code. Here is a brief overview of how the code interacts with
+;; each application:
+;;
+;; Finder.app - grab links to the selected files in the frontmost window
+;; Mail.app - grab links to the selected messages in the message list
+;; AddressBook.app - Grab links to the selected addressbook Cards
+;; Firefox.app - Grab the url of the frontmost tab in the frontmost window
+;; Vimperator/Firefox.app - Grab the url of the frontmost tab in the frontmost window
+;; Safari.app - Grab the url of the frontmost tab in the frontmost window
+;; Google Chrome.app - Grab the url of the frontmost tab in the frontmost window
+;; Together.app - Grab links to the selected items in the library list
+;;
+;;
+;; Installation:
+;;
+;; add (require 'org-mac-link-grabber) to your .emacs, and optionally
+;; bind a key to activate the link grabber menu, like this:
+;;
+;; (add-hook 'org-mode-hook (lambda ()
+;; (define-key org-mode-map (kbd "C-c g") 'omlg-grab-link)))
+;;
+;;
+;; Usage:
+;;
+;; Type C-c g (or whatever key you defined, as above), or type M-x
+;; omlg-grab-link RET to activate the link grabber. This will present
+;; you with a menu to choose an application from which to grab a link
+;; to insert at point. You may also type C-g to abort.
+;;
+;; Customizing:
+;;
+;; You may customize which applications appear in the grab menu by
+;; customizing the group org-mac-link-grabber. Changes take effect
+;; immediately.
