This project has no relations to the appspot (by Google) project. Standard disclaimers apply. In short: If you borrow my chainsaw without asking me and end up bruising yourself while trimming the hedges, you may not hold me responsible. Same applies with the code here.
The code here is in active development and there are no downloads for production environment. I don't foresee any possibility of a stable, production build of the code here anytime soon. However, please feel free to fork and adapt the code here at your own risk. If you are going to use it in a commercial environment, please note that you and only you are responsible to ensure you have the adequate legal protection for such use. I expressly disclaim any liability from use in a production and/or commercial environment.
