-/* This example shows how to declare and start your actors.
- *
- * The first step is to declare the code of your actors (what they do exactly does not matter to this example) and then
- * you ask SimGrid to start your actors. There is three ways of doing so:
- * - Directly, by instantiating your actor as paramter to Actor::create()
- * - By first registering your actors before instantiating it;
- * - Through the deployment file.
- *
- * This example shows all these solutions, even if you obviously should use only one of these solutions to start your
- * actors. The most advised solution is to use a deployment file, as it creates a clear separation between your
- * application and the settings to test it. This is a better scientific methodology. Actually, starting an actor with
- * Actor::create() is mostly useful to start an actor from another actor.
