This document discusses Play! Scala, a framework that allows building web applications in Scala on the Play! platform. It can use Scala instead of Java for the Play! framework. Anorm is used to interact with databases instead of JPA/Hibernate. Play! Scala applications can be deployed to PaaS platforms like Heroku and CloudBees. The document provides links for documentation, mailing lists and the GitHub repository for further information.
