/* It also uses the LED-Notify-Plugin				*/
/* for pidgin, you can find this at				*/
/* http://simo.h.mattila.googlepages.com/led-notification	*/

/* What you have to do to get this running on your system:	*/
/* - build the usb-lcd-module, flash with the usb-lcd code	*/
/* - build the commandline-tool from usb-lcd-module-code	*/
/* - put + of 3 LEDs to PB3-PB5 of Atmega			*/
/* - download the pidgin-led-notifier, set path for led-file	*/
/* - change path in THIS file to your led-file			*/
