Can I ask abit of a silly question....
This file, does it need to be part of a gradle project itself with a build.gradle to get the clikt dependency?
Or I guess the question is how does one run it from the terminal whilst grabbing the dependencies needed?
Thanks!

I created a repo for this:

You just execute it, the kotlin compiler will fetch the dependencies and cache the compilation.
