 // This is the base class for all DOM event targets. To make your class an
 // EventTarget, follow these steps:
 // - Make your IDL interface inherit from EventTarget.
 // - Inherit from EventTargetWithInlineData (only in rare cases should you use
 //   EventTarget directly).
 // - Figure out if you now need to inherit from ActiveDOMObject as well.
 // - In your class declaration, you will typically use
-//   REFCOUNTED_EVENT_TARGET(YourClassName) and
-//   WILL_BE_USING_GARBAGE_COLLECTED_MIXIN(YourClassName). Make sure to include
-//   this header file in your .h file, or you will get very strange compiler
-//   errors.
+//   REFCOUNTED_EVENT_TARGET(YourClassName).
 // - Call ScriptWrappable::init(this) in your constructor, unless you are already
 //   doing so.
 // - Override EventTarget::interfaceName() and executionContext(). The former
 //   will typically return EventTargetNames::YourClassName. The latter will
 //   return ActiveDOMObject::executionContext (if you are an ActiveDOMObject)
 //   or the document you're in.
 // - Your trace() method will need to call EventTargetWithInlineData::trace.
 //
 // Optionally, add a FooEvent.idl class, but that's outside the scope of this
 // comment (and much more straightforward).
