Stores notification settings used by Growl, a notification program for Mac OS X; gives information to a specific program about what alerts and messages should be displayed to the user.

Individual Growl notification files are created for each supported application. For example, "GrowlTunes.growlTicket" is the notification file for iTunes, while "GrowlSafari.growlTicket" is used by Safari.

GrowlTicket files are saved in the user's application support directory located at "~/Library/Application Support/Growl."
