Use notifications in a simple and elegant way. :)
gem install notifiers
require 'notifiers'
include Notifiers
growl.message('Hi Growl!').image('my_image.png').priority(2).name('my_app').notify!
notify_send.image('my_image.png').message('Hi Growl').notify!
Obs.: #notify_send is an alias to #lib_notify .
knotify.title('Hello World').message('Hi!').notify!
