I wanted to use protobuf in my Unity project, and I found that it could be only installed via nuget packages, which do not work with Unity. So I searched for other protobuf plugins for Unity, and it either had too much abstraction around it, or provided GUIs that I didn't really care. This package includes only the protobuf dll binaries that Google provided, and nothing more. I removed duplicate dlls for different frameworks, because Unity complained about them. That's all. This is the protobuf as-is.
