+
+Abstract: Hooks existing preferences/about/quit functionality from an
+ existing Java app into handlers for the Mac OS X application menu.
+ Uses a Proxy object to dynamically implement the
+ com.apple.eawt.ApplicationListener interface and register it with the
+ com.apple.eawt.Application object. This allows the complete project
+ to be both built and run on any platform without any stubs or
+ placeholders. Useful for developers looking to implement Mac OS X
+ features while supporting multiple platforms with minimal impact.
