+ - **ns-3 as a SimGrid Network Model**
+ This simple ping-pong example demonstrates how to use the bindings to the Network
+ Simulator. The most interesting is probably not the C++ files since
+ they are unchanged from the other simulations, but the associated files,
+ such as the platform file to see how to declare a platform to be used
+ with the ns-3 bindings of SimGrid and the tesh file to see how to actually
+ start a simulation in these settings.
