1.3.1 (25 February 2007):
 * Okay, now it's not broken.
 * One-line fix; default baud rate in 1.3 was set to 38400, which isn't
   supported at default 1Mhz clock rate.

1.3 (1 September 2006):
 * This may be broken; I didn't check very carefully
 * But, it does work with avr-libc-1.2.3 on my ubuntu system

1.2.1 (30 March 2006):
 * Sorry, 1.2 was totally broken
 * Explicitly setting baud rate to 4800 in gadgetboard.c fixes the
   problem now that global.h lists the right CPU frequency (1 line fix)

1.2 (15 March 2006): 
 * Added "setall" and "readall" commands to command line interface. 
 * Added bypass caps.
 * Default CPU speed is now 1Mhz, so default baud rate will be 4800
