Broadcast is an example to show RPC Broadcast in action.  If nothing else, you can see how many RPC Servers are running on your network!

RPCInfo is an example that displays the services attached to a Portmapper.

Client/Server is a moderately complex example that configures a Server with multiple Client connections. It shows how to run the jrpcgen with a .x file in addition to showing how and why jrpcgen's unique features make round-trip engineering a reality!
