Growl is a global notifications system for the Mac OS X operating system. Applications can use Growl to display small notifications about events which the user deems important, in a consistent manner. This allows users to fully control their notifications, application developers to spend little time creating notifications, and Growl developers to concentrate on the usability of notifications.Growl installs itself as a preference pane added to the Mac OS X System Preferences. This pane enables and disables Growl's notifications for certain applications entirely, or select specific notifications for each application.Applications register a ticket with Growl, then send arbitrary notifications which Growl receives and displays. Each notification provides some information, such as: Download finished, or the name of the current iTunes track. Users can customize the display and turn notifications on and off.Growl includes bindings for developers who use the Objective-C, C, Perl, Python, Tcl, AppleScript, Java, and Ruby programming languages, and comes with multiple display plugins, providing different styles for presenting the notifications.  [edit]  Less
