+ * @section MSG_ex_models Models-related examples
+ *
+ * @subsection MSG_ex_PLS Packet level simulators
+ *
+ * These examples demonstrate how to use the bindings to classical
+ * Packet-Level Simulators (PLS), as explained in \ref pls. 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 files to see how to declare a platform to be used with
+ * the PLS bindings of SimGrid and the tesh files to see how to
+ * actually start a simulation in these settings.
+ *
+ * - <b>ns3</b>: Simple ping-pong using ns3 instead of the SimGrid network models.
