+## Kotlin Swing
+
+The Kotlin Swing library provides some helper functions and extensions for creating Swing user interfaces.
+
+To try the sample run
+
+    mvn test -Pui
+
+Or browse the [source of the sample](https://github.com/JetBrains/kotlin/blob/master/libraries/kotlin-swing/src/test/kotlin/test/kotlin/swing/SwingSample.kt)
+to see the kinds of features available
