Extras/GrowlMail/GrowlMail_Prefix.pch
2009-06-06 Refactored GrowlMail to have a separate singleton notifier object, in order to make the mail-bundle class less dependent on being a singleton. (Assumptions are bad, especially when you're working with private/undocumented APIs.)
2004-11-13 Moving GrowlSafari/Mail/Tunes to the Extras folder.
