Jetbrains provides some documentation but I can\'t find how to run compiled class file of Kotlin.
hello.kt:
fun main(args : Array) {
We ran into the same program and blogged our solution here: http://blog.ocheyedan.net/blog/2012/02/19/running-kotlin-code/
Basically you just need to invoke java with the -cp and the main class of 'namespace'. From your question, the java invocation would look something like this:
java -cp /usr/local/kotlin/lib/kotlin-runtime.jar:dist/namespace.class namespace
