+//
+// Example program demonstrating how to use
+// RH_LoRaFileOps driver on RPi+Linux with a radio supported by
+// the LoRa-file-ops Linix driver, such as the SX1278.
+// See See https://github.com/starnight/LoRa/tree/file-ops
+//
+// You can build this in the top level RadioHead directory with something like:
+// cd RadioHead
+// g++ -o lorafileops_client -I . RH_LoRaFileOps.cpp RHGenericDriver.cpp tools/simMain.cpp examples/lorafileops/lorafileops_client/lorafileops_client.cpp
+//
+// And run with
+// sudo ./lorafileops_client 
+//  (root needed to open /dev/loraSPI0.0
+//
+// Ensure a RadioHead LoRa compatible receiver is running
+// with modem config RH_RF95::Bw125Cr45Sf2048
+// eg examples/rf95/rf95_server/rf95_server.pde 
+// or
+// examples/lorafileops/lorafileops_server/lorafileops_server.cpp
+
