How to use scala to write command line tools

Question

I want to use scala to write some command line tools. I found a conscript repository , this seems to be what I'm looking for, but I miss the document and examples in which I have a lot of problems using to create a simple demo Hello world.

Is there any other way to use scala to write command line tools?

The accepted answer to this question still looks good for a start, since it is important to be well versed in the parameters and parameters. The scopt project mentioned there still looks lively and decently documented.
