-// Encapsulates a connection to the Mojo Shell in two parts:
-// - a bound InterfacePtr to mojo::shell::mojom::Shell, the primary mechanism
-//   by which the instantiating application interacts with other services
-//   brokered by the Mojo Shell.
-// - a bound InterfaceRequest of mojo::shell::mojom::ShellClient, an interface
-//   used by the Mojo Shell to inform this application of lifecycle events and
-//   inbound connections brokered by it.
-//
-// This class should be used in two scenarios:
-// - During early startup to bind the mojo::shell::mojom::ShellClientRequest
-//   obtained from the Mojo Shell. This is typically in response to either
-//   MojoMain() or main().
-// - In an implementation of mojo::shell::mojom::ContentHandler to bind the
-//   mojo::shell::mojom::ShellClientRequest passed via StartApplication. In this
-//   scenario there can be many instances of this class per process.
-//
-// Instances of this class are constructed with an implementation of the Shell
-// Client Lib's mojo::ShellClient interface. See documentation in shell_client.h
-// for details.
