A simple Emacs Lisp module for interfacing with
terminal-notifier for the OS X

Copy or clone terminal-notifier.el into a reasonable spot on your Emacs
load-path.
(tn-notify "Ahoy, message!" "Whoa there, title!" "Yo, subtitle!")
Will display a notification like this:
That's about it. I find it handy for notifying that a longer asynchronous
process has finished, e.g., set-process-sentinel.
