+// protoc-gen-go-grpc is a plugin for the Google protocol buffer compiler to
+// generate Go code. Install it by building this program and making it
+// accessible within your PATH with the name:
+//
+//	protoc-gen-go-grpc
+//
+// The 'go-grpc' suffix becomes part of the argument for the protocol compiler,
+// such that it can be invoked as:
+//
+//	protoc --go-grpc_out=. path/to/file.proto
+//
+// This generates Go service definitions for the protocol buffer defined by
+// file.proto.  With that input, the output will be written to:
+//
+//	path/to/file_grpc.pb.go
