+ * #include "DebounceIn.h"
+ *
+ * DebounceIn  d(p5);
+ * DigitialOut led1(LED1);
+ * DigitialOut led2(LED2);

+ *     }
+ * }
+ * @endcode
+ *
+ * @see set_debounce_us() To change the sampling frequency.
+ * @see set_samples() To alter the number of samples.
+ *
+ * Users of this library may also be interested in PinDetect library:-
+ * @see http://mbed.org/users/AjK/libraries/PinDetect/latest
+ *
+ * This example shows one input displayed by two outputs. The input
+ * is debounced by the default 10ms.
