1 '''Access to the Wiimote in pygame
2
3 I tried to mimic the Joystick interface already in pygame.
4
5 The usuage pattern is
6
7 init the module telling it the maximum number of wiimotes and the timeout
8 get_count to determine how many you got
9 Wiimote(n) to get an object referencing the nth wiimote
10
11 Free for any use. If you or your lawyer are stupid enough to believe I have any liability for
12 this, then don't use it; otherwise be my guest.
