gRPC Python: Instructions for Local Development

Note: The compilation of the C files (make) requires GCC version 7. Maybe LLVM?

1. Git clone & init the project

git clone ...
git submodule update --init

Aio gRPC

A Proposal from the user's perspective

As a user, to use the new implementation of gRCP in the asynchronous version, I will compile by passing a specific flag:

$ python -m grpc_tools.protoc -I. --python_out=. --grpc_python_out=. proto/echo.proto --aiogrpc

This compiles the stubs, generated with the asynchronous code.
