macnotify

The macnotify package is designed to bounce Mac applications on the Dock when the application is not frontmost on the screen and it displays an alert (in the form of a tk_messageBox). The package works via a combination of Tcl and AppleScript. It provides functionality similar to Daniel Steffen's tclCarbonNotification package, but is a script-level package and thus does not require compilation.

Macnotify is developed by Kevin Walzer and is available at http://opensource.codebykevin.com
