title: Which file should I edit to change the breadcrumbs starting point?
body: <p>I wanted to change the breadcrumbs starting point from Home to My title. I edited the file  <code>/magento/app/code/core/Mage/Catalog/Block/Breadcrumbs.php</code> but it doesn't seem to be working. Is XML playing a role in that?</p>
  
  <p>thanks</p>
