Use this to make autotest work with Growl.

# save this file as ~/.autotest
# start autospec with ./script/autospec

# you may need to install the "autotest" and "autotest-rails-pure" gems

# if you have any issues getting this to work (like Growl notifications not appearing),
# take a look at the README found here: http://github.com/svoop/autotest-growl
