- * Firmata, the general purpose sensorbox firmware for Arduino
- * -----------------------------------------------------------
- * 
- * Firmata turns the Arduino into a Plug-n-Play sensorbox, servo
- * controller, and/or PWM motor/lamp controller.
- *
- * It was originally designed to work with the Pd object [arduino]
- * which is included in Pd-extended.  This firmware is intended to
- * work with any host computer software package.  It can easily be
- * used with other programs like Max/MSP, Processing, or whatever can
- * do serial communications.
- *
- * @author: Hans-Christoph Steiner <hans@at.or.at>
- *   help with initial protocol redesign: Jamie Allen <jamie@heavyside.net>
- *   much protocol discussion: the Arduino developers mailing list
- *   key bugfixes: Georg Holzmann <grh@mur.at>

- * trouble and can be parsed by standard MIDI interpreters.  Just some of the
