Examples of usage

Activate Spotify

terminal-notifier 'New music!' -t Spotify -a 'com.Spotify.client' 

Open a website

terminal-notifier 'Tiny API with Nginx' -t c7.se -o 'http://c7.se/tiny-api-with-nginx/'

Version 1.3.0 of the terminal-notifier gem was just released and it has a built in command line interface, so you should probably use that instead :)
