So currently, you can buy Growl 1.3 off the App Store, however they have not released the source yet or so it appears. How can we developers grab the source to modify it and have it do what we want? http://growl.info/hg/ haven't been updated since June. https://code.google.com/p/growl/source/list hasn't been updated since June 2010 however they are using their Google Code page as a bug reporter. So how can I, a developer, get source code of 1.3?
