Pedestal: A Mac OS Application Framework
Pedestal is a Mac OS application framework. Originally, the intent of Pedestal was to provide the standard behavior expected of Mac applications. Since then it has diverged slightly into a prototype for some alternative ideas advocated by Jef Raskin in The Humane Interface.
Post-1997 system software such as Window Manager 8.5 and the Carbon Event Manager provide functionality overlapping with Pedestal's. A future goal is to morph Pedestal into an implemention of these APIs for earlier systems.
