+// RasPiRH.cpp
+//
+// Example program showing how to use RH_NRF24 on Raspberry Pi
+// Uses the bcm2835 library to access the GPIO pins to drive the NRF24L01
+// Requires bcm2835 library to be already installed
+// http://www.airspayce.com/mikem/bcm2835/
+// Use the Makefile in this directory:
+// cd example/raspi
+// make
+// sudo ./RasPiRH
+//
+// Creates a RHReliableDatagram manager and listens and prints for reliable datagrams
+// sent to it on the default Channel 2.
