some details: this is runtime based function resolving will be replaced with compile time soon.
example:
-----------------8<-----------------
> cat ../backend.native/tests/runtime/basic/hello2.kt
// TODO: remove kotlin_native.io once overrides are in place.
fun main(args : Array<String>) {
print("you entered '" + readLine() + "'")
}
-----------------8<-----------------
translator generates following (reduced)

Kotlin-native backend
Build
Download dependencies:
gradle :dependencies:update
To run native translator just use:
gradle :backend.native:run
And it will run simple example (currently prints out IR of test file). For more tests, use:
gradle :backend.native:tests:run
