 This will create three new services:

-Type-hints and Auto-wiring
---------------------------
-
-Auto-wiring is a great feature that allows you to reduce the amount of configuration
-required for your service container to be created. By using ``MessageBusInterface``
-as argument type-hint in your services, the default configured bus will be injected
-(i.e ``messenger.bus.commands`` in above examples).
-
-When working with multiple buses, you can use the ``DependencyInjection`` component's
-binding capabilities to clarify which bus will be injected based on the argument's name:
