+// Sample code for calling the DinkeyRemote module
+
+// The sample code contains 2 functions. The sample code is just a guide.  
+
+// There are two methods to loading a DRPF file. These are shown in the first two functions:
+// DoUpdateCode and DoUpdateCodewithMod
+
+// DoUpdateCode: we load the DRPF file from disk and get a handle and use it "as is" using the API
+//                  call LoadDRPFFromFile. You can make some limited changes to overwrite the default
+//                  behaviour by using API flags.
+                     
+// DoUpdateCodewithMod: we load the DRPF file from disk and load into structures. We can then modify the
+//                      DRPF settings by modifying this structure. This method uses the API calls
+//                      ReadDRPFEx and LoadDRPF.
