Remote Procedure Calls (RPCs) provide a useful abstraction for building distributed applications and services.

gRPC is a modern open source high performance RPC framework that can run in any environment.

Protocol Buffers (Protobuf) are a flexible, efficient, automated mechanism for serializing structured data - similar to XML, but smaller, faster, and simpler.

This package provides the Protobuf protocol definitions (.proto files) for gRPC services.
