* @section MSG_ex_actions Trace driven simulations
*
- * The <b>actions/actions.c</b> example demonstrates how to run trace-driven simulations. It
- * is very handy when you want to test an algorithm or protocol that
- * does nothing unless it receives some events from outside. For
- * example, a P2P protocol reacts to requests from the user, but
- * does nothing if there is no such event.
+ * The <b>actions/actions.c</b> example demonstrates how to run trace-driven simulations. It is very handy when you
+ * want to test an algorithm or protocol that does nothing unless it receives some events from outside. For example,
+ * a P2P protocol reacts to requests from the user, but does nothing if there is no such event.
*
- * In such situations, SimGrid allows to write your protocol in your
- * C file, and the events to react to in a separate text file.
- * Declare a function handling each of the events that you want to
- * accept in your trace files, register them using \ref
- * xbt_replay_action_register in your main, and then use \ref
- * MSG_action_trace_run to launch the simulation. You can either
- * have one trace file containing all your events, or a file per
- * simulated process. Check the tesh files in the example directory
- * for details on how to do it.

- * This example uses this approach to replay MPI-like traces. It

- * is somehow similar to SMPI, yet differently implemented. This
- * code should probably be changed to use SMPI internals instead,
- * but wasn't, so far.
