title: How to import popper.js?
body: <p>It seems to be a lame question, but I cannot figure it out. How to import popper.js which comes together with Bootstrap 4 beta?</p>
  <p>I use Bower, and I've installed Bootstrap 4 beta. Now in the <code>bower_components</code> folder, there is the <code>popper.js</code> directory, which contains a few sub-folders. The problem is there is no <code>dist</code> folder and the <code>popper.min.js</code> file.</p>
  <p>Bootstrap 4 guide links to CDN: <code>https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js</code>.</p>
  <p>How to import <code>popper.js</code> without CDN? Where to find the <code>popper.min.js</code> file?</p>
  <p>EDIT: Even if I download a <code>zip</code> file from the popper.js website, it contains the same files as I've downloaded from <code>Bower</code>.</p>
