title: How to use scala to write command line tools
body: <p>I want to use scala to write some command line tools. I found a repository <a href="https://github.com/n8han/conscript" rel="noreferrer">conscript</a>, it seems is what I'm looking for, but lacks document and examples that I have a lot of troubles using it to create a simple <code>Hello world</code> demo.</p>
  
  <p>Is there any other way to use scala to write command line tools?</p>
