title: Is it normal for Gulp to include so many node_modules when installing Gulp?
body: <p>I just installed Gulp with the following commands:</p>
  
  <pre><code>npm install --global gulp
  </code></pre>
  
  <p>and </p>
  
  <pre><code>npm install --save-dev gulp
  </code></pre>
  
  <p>Everything works fine except my node_modules folder is now filled with modules I have never heard of. All the tutorials online about Gulp only show the Gulp module in this folder. For me it's the following:</p>
  
  <p><a href="http://i.stack.imgur.com/hCJdg.png">node_modules folder</a></p>
  
  <p><strong>Question:</strong></p>
  
  <p>Is it normal for the node_modules folder to be having these modules?</p>
  
  <p>Thank you in advance</p>
