-// specified InterfacePtr to one end of the message pipe, and returns an
-// InterfaceRequest bound to the other. The InterfacePtr should be passed to
-// the client, and the InterfaceRequest should be passed to whatever will
-// provide the implementation. The implementation should typically be bound to
-// the InterfaceRequest using the Binding or StrongBinding classes. The client
-// may begin to issue calls even before an implementation has been bound, since
-// messages sent over the pipe will just queue up until they are consumed by
-// the implementation.

-// Example #1: Requesting a remote implementation of an interface.
-// ===============================================================
-//
-// Given the following interface:
-//
-// interface Database {
-// OpenTable(Table& table);
-// }
-//
-// The client would have code similar to the following:
-//
-// DatabasePtr database = ...; // Connect to database.
-// TablePtr table;
-// database->OpenTable(GetProxy(&table));
-//
-// Upon return from GetProxy, |table| is ready to have methods called on it.

-// Example #2: Registering a local implementation with a remote service.
-// =====================================================================
-//
-// Given the following interface
-// interface Collector {
-// RegisterSource(Source source);
-// }
-//
-// The client would have code similar to the following:
-//
-// CollectorPtr collector = ...; // Connect to Collector.
-// SourcePtr source;
-// InterfaceRequest<Source> source_request = GetProxy(&source);
-// collector->RegisterSource(source.Pass());
-// CreateSource(source_request.Pass()); // Create implementation locally.
