code: def crumb_link(context, name, *args, **kwargs):
      
      url = reverse(name, args=args, kwargs=kwargs)
      label = find_crumb(context['request'], url)
      return u'<a href="%s">%s</a>' % (url, label)
docs: Acts like :func:`named_crumb` but also wraps the result into a
      link tag. Usage::
  
          <ul>
              <li>{% crumb_link 'auth_login' %}</li>
              <li>{% crumb_link 'project-index' %}</li>
          </ul>
  
      The result::
  
          <ul>
              <li><a href="/accounts/login/">Log in</a></li>
              <li><a href="/projects/">Projects</a></li>
          </ul>
