 169  <h3>What does this do?</h3>
 170  <p>Prints a breadcrumb trail .</p>
 171  <h3>How do I use it?</h3>
 172  <p>Just insert the tag into your template/page like: <code>{breadcrumbs}</code></p>
 173  <h3>What parameters does it take?</h3>
 174  <p>
 175  <ul>
 176  <li><em>(optional)</em> <tt>delimiter</tt> - Text to seperate entries in the list (default "&gt;&gt;").</li>
 177  <li><em>(optional)</em> <tt>initial</tt> - 1/0 If set to 1 start the breadcrumbs with a delimiter (default 0).</li>
 178  <li><em>(optional)</em> <tt>root</tt> - Page alias of a page you want to always appear as the first page in
 179      the list. Can be used to make a page (e.g. the front page) appear to be the root of everything even though it is not.</li>
 180  <li><em>(optional)</em> <tt>root_url</tt> - Override the URL of the root page. Useful for making link be to '/' instead of '/home/'. This requires that the root page be set as the default page.</li>
 181  
 182  <li><em>(optional)</em> <tt>classid</tt> - The CSS class for the non current page names, i.e. the first n-1 pages in the list. If the name is a link it is added to the &lt;a href&gt; tags, otherwise it is added to the &lt;span&gt; tags.</li>
 183  <li><em>(optional)</em> <tt>currentclassid</tt> - The CSS class for the &lt;span&gt; tag surrounding the current page name.</li>
 184  <li><em>(optional)</em> <tt>starttext</tt> - Text to append to the front of the breadcrumbs list, something like &quot;You are here&quot;.</li>
 185  </ul>
