Arduino/hardware/libraries/EEPROM/examples/eeprom_write/eeprom_write.pde
David A. Mellis 2fa8deb92d First integration of the Arduino code in Processing 5503: PreProcessor and Compiler have been integrated with changes to the Sketch.
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).
