 This is a simple Java library containing a [protocol buffer](https://developers.google.com/protocol-buffers) model and serializer. It can be used in case you want to generate [\*.proto files](https://developers.google.com/protocol-buffers/docs/proto3) within a Java application. We currently support [proto3](https://developers.google.com/protocol-buffers/docs/proto3) only.
