    # And now you have to ask SimGrid to actually start your actors.
    #
    # The easiest way to do so is to implement the behavior of your actor in a single function,
    # as we do here for the receiver actors. This function can take any kind of parameters, as
    # long as the last parameters of Actor::create() match what your function expects.
    Actor.create("receiver", Host.by_name("Fafard"), receiver, "mb42")

    # If your actor is getting more complex, you probably want to implement it as a class instead,
    # as we do here for the sender actors. The main behavior goes into operator()() of the class.
    #
    # You can then directly start your actor, as follows:
    Actor.create("sender1", Host.by_name("Tremblay"), Sender())
    # If you want to pass parameters to your class, that's very easy: just use your constructors
    Actor.create("sender2", Host.by_name("Jupiter"), Sender("GloubiBoulga"))

    # But starting actors directly is considered as a bad experimental habit, since it ties the code
    # you want to test with the experimental scenario. Starting your actors from an external deployment
    # file in XML ensures that you can test your code in several scenarios without changing the code itself.
    #
    # For that, you first need to register your function or your actor as follows.
    e.register_actor("sender", Sender)
    e.register_actor("forwarder", forwarder)
    # Once actors and functions are registered, just load the deployment file
    e.load_deployment("actor-create_d.xml")

    # Once every actors are started in the engine, the simulation can start
    e.run()

    # Once the simulation is done, the program is ended
