'''The Ping-Pong Example''' To help getting into using Ariba, we provide a short example of how to use the architecture. For this, assume a simple service whose simply and only intention is to exchange data packets between two participating nodes, just like playing ping pong. You will find the whole code within the package under ''sample/pingpong''. The source files divide into the main code (''PingPong.h/.cpp'') and the used message format (declared in ''PingPongMessage.h/.cpp''). In Addition, ''main.cpp'' acts as the entry point to the ping-pong example. We will first give a high-level introduction about what the example does and later dig deeper into the code.
