Simple Build Tool 0.13

Simple Build Tool (sbt) is a build tool for Scala and mixed Scala/Java projects that provides developers with a high productivity work environment.
sbt knows how to compile Scala code, to run tests, to package jars and wars, and to start the Scala interpreter with the right classpath. Build definitions are specified using a Scala domain specific language (DSL), in a mix of declarative and imperative styles.
