SBT stands for Simple Build Tool and it uses the Scala syntax to define how a project is built, managing dependencies, and so on. It uses .sbt files for this purpose. It also supports a setup based on Scala code in .scala files, as well as a mix of both.
To download SBT, go to http://www.scala-sbt.org/1.0/docs/Setup.html and follow the instructions. If you wish to obtain the newest version, then simply Google it and use the result you get back.
