`krt` provides a framework for building _declarative_ controllers.
See the [design doc](https://docs.google.com/document/d/1-ywpCnOfubqg7WAXSPf4YgbaFDBEU9HIqMWcxZLhzwE/edit#heading=h.ffjmk8byb9gt) and [KubeCon talk](https://sched.co/1R2oY) for more background.

The framework aims to solve a few problems with writing controllers:
