Growl notifications with autotest made easy

Setting up a new project to use growl notification via autotest can be a bit tricky. There is a fantastic gem called growl-glue that can simplify the whole procedure. Simply:

[sudo] gem install growl-glue

Then add the following lines to your .autotest file:

require 'growl_glue'
GrowlGlue::Autotest.initialize

initialize will accept a block containing a stack of different configuration options. Take a look at what is possible here.
