title: OpenGTS Change/edit Interface
body: <p>I had been working with OpenGTS, According to what I read, the files are located in the <code>$GTS_HOME / build / track</code>, after you change/edit it as you want to edit either the CSS, JSP, etc. whatever you want, you need to compile the 
  (ant track) again and ready. The problem is that I do these steps and do not work for me.</p>
  
  <p>I would like to know, How can i change/edit the interface of this platform?</p>
