Source obtained from http://sourceforge.net/projects/wmacpi/files/. 2003 July 6 0.50 Finally got rid of that annoying button - that space now contains a 'B 1' or 'B 2' (only those two at present, since I'm too lazy to fix it so that the number is generic. It should work fine for anyone who doesn't have a freakish system with more than two batteries . . .) A few more code cleanups.
