/**
 * Small utility script to use JavaFX 2 from scala REPL
 * To use ':l fxutil.scala' in REPL.
 * Recent java7 JDK contains javafx runtime at $JAVA_HOME/jre/lib/jfxrt.jar
 * Scala 2.9 takes -cp or CLASSPATH, so specify the jfxrt.jar path using
 * either way.
 * Scala 2.10 does not work in the same way.  Its startup script passes
 * -classpath "", thus -cp does not work.  Instead, it has -toolcp option,
 * so specify the jfxrt.jar using the option.
