title: How to use sourcemaps to restore the original file?
body: <p>I have a file that has been transpiled from ES6 to ES5 using Babel. I have sourcemap. I am assuming I can restore the original file (the way it looked when written in ES6) using these resources.</p>
  
  <p>How is it done?</p>
  
  <p>Is there a CLI tool to do this?</p>
