title: How do I fix "no-unused-vars" for main entry Browserify js file?
body: <p>I use Gulp and Browserify to be able to use ES6 imports, as well as ESLint to apply coding standards.</p>
  
  <p>So I need one entry file for Browserify which only imports all my other files:</p>
  
  <pre><code>import Carousel from "./bootstrap/carousel";
  import Transition from "./bootstrap/transition";
  import Header from "./header/header";
  </code></pre>
  
  <p>Unfortunately, ESLint complains </p>
  
  <pre><code>data/themes/js/src/main.js
    1:8  error  'Carousel' is defined but never used    no-unused-vars
    2:8  error  'Transition' is defined but never used  no-unused-vars
    3:8  error  'Header' is defined but never used      no-unused-vars
  </code></pre>
  
  <p>I wouldn't like to disable the rule (although I could do it only for that file)</p>
