  33  *      Since Wiiuse is a library, wiiuse.h is a duplicate
  34  *      of the API header.
  35  *
  36  *      The code that would normally go in that file, but
  37  *      which is not needed by third party developers,
  38  *      is put here.
  39  *
  40  *      So wiiuse_internal.h is included by other files
  41  *      internally, wiiuse.h is included only here.
