## wwapi generate code from protobuf. Requires protoc and protoc-grpc-gen-gateway to generate code.
## To setup latest protoc:
##    Download the protobuf-all-[VERSION].tar.gz from https://github.com/protocolbuffers/protobuf/releases
##    Extract the contents and change in the directory
##    ./configure
##    make
##    make check
##    sudo make install
##    sudo ldconfig # refresh shared library cache.
## To setup protoc-gen-grpc-gateway, see https://github.com/grpc-ecosystem/grpc-gateway
