  32    This is a stub driver header file, for implementing custom board
  33    layout hardware with compatible LUFA board specific drivers. If
  34    the library is configured to use the BOARD_USER board mode, this
  35    driver file should be completed and copied into the "/Board/" folder
  36    inside the application's folder.
  37
  38    This stub is for the board-specific component of the LUFA Buttons driver,
  39    for the control of physical board-mounted GPIO pushbuttons.
