A simplified machine learning container platform that helps teams get started with an automated workflow.
DISCLAIMER: dama is currently in alpha due to the lack of security and scaling, but still fun to try out!

make build
- Tokenize environment variables in DB
- Write test suite
- Provide Vagrant and Docker images
- Add scheduler / resource manager for multi-host container serving
- Rewrite auth middleware
- Swap out stdlib flags package for third-party package
- These docs stink!
