Making stand-alone jar with Simple Build Tool

Question

Is there a way to tell sbt to package all needed libraries (scala-library.jar) into the main package, so it is stand-alone? (static?)

Answer 1

Working off of what @retronym offered above, I built a simple example that builds a stand alone jar which includes the Scala libraries (i.e. scala-library.jar) using Proguard with sbt. Thanks, retronym.
