+/** \file
+ *  \brief LUFA Custom Board LED Hardware Driver (Template)
+ *
+ *  This is a stub driver header file, for implementing custom board
+ *  layout hardware with compatible LUFA board specific drivers. If
+ *  the library is configured to use the BOARD_USER board mode, this
+ *  driver file should be completed and copied into the "/Board/" folder
+ *  inside the application's folder.
+ *
+ *  This stub is for the board-specific component of the LUFA LEDs driver,
+ *  for the LEDs (up to four) mounted on most development boards.
