Jetbrains provides some documentation but I can\'t find how to run compiled class file of Kotlin.
hello.kt:
fun main(args : Array) {
Update: In the newer versions of the Kotlin IDE plugin, you can use context Run-actions in the Editors pop-up menu.
If you are in the IDE, right-click the editor and choose "Run namespace" Otherwise, compile and run the *.namespace class as a normal Java class.
