title: SugarCRM Home Page URL
body: <p>I am using sugarCRM Open Source Application for my own purpose.
  When I click the Home link the above URL is like: </p>
  
  <p><code>ajaxUILoc=index.php?module=Home&amp;action=index&amp;ParentTab=sales</code></p>
  
  <p>How can I find out the flow of code using the above url. I have verified the sugarCRM developers guide regarding the url, but I cannot get the solution.  How they call the functions or classes using like this.</p>
  
  <p>Actually why I am asking is I want to modify the existing code to add some extra modules.
  I am struggling for last one week without solution.</p>
