+ * Description:
+ *   board_button_initialize() must be called to initialize button resources.
+ *   After that, board_buttons() may be called to collect the current state of
+ *   all buttons or board_button_irq() may be called to register button interrupt
+ *   handlers.
+ *
+ *   After board_button_initialize() has been called, board_buttons() may be
+ *   called to collect the state of all buttons.  board_buttons() returns an
+ *   8-bit bit set with each bit associated with a button.  See the
+ *   BUTTON_*_BIT and JOYSTICK_*_BIT definitions in board.h for the meaning
+ *   of each bit.
+ *
+ *   board_button_irq() may be called to register an interrupt handler that will
+ *   be called when a button is depressed or released.  The ID value is a
+ *   button enumeration value that uniquely identifies a button resource.
+ *   See the BUTTON_* and JOYSTICK_* definitions in board.h for the meaning
+ *   of enumeration value.  The previous interrupt handler address is
+ *   returned (so that it may be restored, if so desired).
