+* WiiClassicControllerReader. A program allowing the output of one or two
+* Wii Classic Controllers to be read via I2C and decoded for use, using the mbed 
+* microcontroller and its associated libraries.
+*
+* Written by Alfredo Guerrero <alfredog83@gmail.com> for the mbedGC open-source 
+* game console <http://www.mbedgc.com>. Based on the original code for
+* the WiiNunchuckReader written by Petras Saduikis <petras@petras.co.uk>.
