* WiiUse is a cross-platform C library for accessing the Nintendo Wii
* Remote and its related expansions and variations.
*
* @section project Project
*
* This is a friendly fork of the original WiiUse project, which seems
* to have gone defunct. This updated version incorporates improvements
* from a number of internal forks found across the Internet, and is
* intended to be the new "upstream" of the project. The new homepage is
* on GitHub, where the source is maintained:
