+/*
+ A command line tool to talk to any grpc server.
+ Example of talking to grpc interop server:
+ 1. Prepare request binary file:
+ a. create a text file input.txt, containing the following:
+ response_size: 10
+ payload: {
+ body: "hello world"
+ }
+ b. under grpc/ run
+ protoc --proto_path=test/cpp/interop/ \
+ --encode=grpc.testing.SimpleRequest test/cpp/interop/messages.proto \
+ < input.txt > input.bin
+ 2. Start a server
+ make interop_server && bins/opt/interop_server --port=50051
+ 3. Run the tool
+ make grpc_cli && bins/opt/grpc_cli call localhost:50051 \
+ /grpc.testing.TestService/UnaryCall --enable_ssl=false \
+ --input_binary_file=input.bin --output_binary_file=output.bin
+ 4. Decode response
+ protoc --proto_path=test/cpp/interop/ \
+ --decode=grpc.testing.SimpleResponse test/cpp/interop/messages.proto \
+ < output.bin > output.txt
+ 5. Now the text form of response should be in output.txt
