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