+This project contains prebuilt binaries of the protocol buffer compiler.
+
+protoc is tightly coupled to the source code of libprotobuf-cpp, which is compiled from the sources in external/protobuf.
+
+Therefore, the contents of this folder should match the contents of external/protobuf.
+
+Download source: official protoc artifacts
+URL: https://github.com/protocolbuffers/protobuf/releases/tag/v3.9.1
