How to setup my Grunt file that when min runs it uses a subdirectory?
<p>I'm creating an Angular (generated by Yeoman Angular) app / mini site that needs to run in a subfolder of root</p>

<pre><code>root/festival/
</code></pre>

<p>it all works fabulously until its time to build, and I can't get Grunt to output </p>

<pre><code>/festival/scripts/vendor.js
/festival/scripts/scripts.js
</code></pre>

<p>etc.. </p>

<p>I've been playing around adding "/festival/" whereever I can but nothing is working.</p>

<p>below is my grunt config:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
