function wp_custom_breadcrumbs() {
 
  $showOnHome = 0; // 1 - show breadcrumbs on the homepage, 0 - don't show
  $delimiter = '»'; // delimiter between crumbs
  $home = 'Home'; // text for the 'Home' link

  $before = '<span class="current">'; // tag before the current crumb
  $after = '</span>'; // tag after the current crumb
