How to add breadcrumb? How can I add breadcrumb to a page in my attendance module.

I have used the following hook, but it changed the breadcrumb for all pages in other modules also.

function attendance_init() {
// set the breadcrumb
$breadcrumb = array();
$breadcrumb[] = l('Home', '&lt;front&gt;');
$breadcrumb[] = l('People', 'group/node/'. arg(2) .'/people');
$breadcrumb[] = l('Attendance', 'group/node/'. arg(2) .'/people/attendance');
drupal_set_breadcrumb($breadcrumb);         

}
Could you get what you want from the Custom Breadcrumbs module?


  Allows administrators to set up parametrized breadcrumb trails for any
  node type. This allows CCK-style node types to have "Home > User Blog
  >2005 > January" style breadcrumbs on the node view page itself, synchronizing cleanly with custom views or pathauto aliases.
  Breadcrumb visibility can be customized via a php snippet.
