title: How to minimize Ext JS / Ext Gantt folder for production?
body: <p>I just finished development of a Gantt chart page inside our .NET (WebForms) project using Ext JS and Ext Gantt technology. Works great as I described in a previous <a href="https://stackoverflow.com/questions/9085614/gantt-chart-in-javascript-jquery-extjs/9232475#9232475">post</a>.</p>
  
  <p>My problem now is that my folder container Ext JS and Ext Gantt even after removing obvious overhead is huge compared to the rest of hte project and my team is complaining. So I need to reduce this folder as much as I can just leaving there "exactly" (in a reasonable way) what I need to run the Gantt chart and nothing else for now.   </p>
  
  <p>I did try for a couple of hours but still cannot find a good / easy recipe.<br>
  The following links talk about this but I am still confused:</p>

  <p>Anybody with experience doing this?. I know Ext JS has a tool called builder but I never used it. </p>
