This page includes the following <script> tag:
<script src="http://plovr.com:9810/compile?id=demo&mode=RAW"></script>
If you view the DOM of this page after the single plovr <script>tag is evaluated, you will see that it adds an additional 22 <script> tags to the page. This is because example/main.js depends on Closure Templates, so its set of transitive dependencies is large.
