Also, the Sketchbook and Examples menus are currently disabled on the Mac to work-around a bug in Apple's implementation of Java. I think this bug may have been solved, so I should try re-enabling the menus and see what happens (on 10.4 and 10.5 and 10.6). Also, I may still need to update the jre / jdk on Linux.
Compilation still has problems (Thread error on success, and can't handle non-pde files in a sketch).
Modified the Mac OS X make.sh to copy the hardware, avr tools, and example over.
Removing some of the antlr stuff.
Disabling the Commander (command-line execution) for now.
Added Library, LibraryManager, and Target.
Added support for prefixed preferences (e.g. for boards and programmers).
