Installing sbt

We validate our editorial work using programs written in Scala. You don’t need to install Scala separately, however. We’ll use the simple build tool, sbt, to find code libraries automatically, including Scala.

To install sbt :

• First install a full Java JDK (software development kit). (Note that this is different from Java plugins for your web browser, which you may already have installed.) You can find a JDK for your operating system at http://www.oracle.com/technetwork/java/javase/downloads/index.html
• Download and install sbt from http://www.scala-sbt.org/ (OS X users: if you download the zip or tgz file, make sure sbt/bin is on your CLASSPATH.)
