+"""DEPRECATED:  Declares the RPC service interfaces.
+
+This module declares the abstract interfaces underlying proto2 RPC
+services.  These are intended to be independent of any particular RPC
+implementation, so that proto2 services can be used on top of a variety
+of implementations.  Starting with version 2.3.0, RPC implementations should
+not try to build on these, but should instead provide code generator plugins
+which generate code specific to the particular RPC implementation.  This way
+the generated code can be more appropriate for the implementation in use
+and can avoid unnecessary layers of indirection.
