-// An implementation of shell::mojom::InterfaceProvider that allows the user to
-// register services to be exposed to another application.
-//
-// To use, define a class that implements your specific interface. Then
-// implement an InterfaceFactory<Foo> that binds instances of FooImpl to
-// InterfaceRequest<Foo>s and register that on the registry like this:
-//
-//   registry.AddInterface(&factory);
-//
-// Or, if you have multiple factories implemented by the same type, explicitly
-// specify the interface to register the factory for:
-//
-//   registry.AddInterface<Foo>(&my_foo_and_bar_factory_);
-//   registry.AddInterface<Bar>(&my_foo_and_bar_factory_);
-//
-// The InterfaceFactory must outlive the InterfaceRegistry.
-//
-// Additionally you may specify a default InterfaceBinder to handle requests for
-// interfaces unhandled by any registered InterfaceFactory. Just as with
-// InterfaceFactory, the default InterfaceBinder supplied must outlive
-// InterfaceRegistry.
