title: Browserify multiple files into a single bundle
body: <p>Currently, I browserify a single js file into a bundle.js</p>
  
  <pre><code>$ browserify X1.js --standalone XXX &gt; bundle.js
  </code></pre>
  
  <p>What if I have multiple js files and want to join them into a single browserified bundle.js</p>
  
  <p>How should the command look like? Can I do something like this?</p>
  
  <pre><code>$ browserify X1.js X2.js --standalone XXX &gt; bundle.js
  </code></pre>
  
  <p>I am using node.js v6</p>
