<h3>What does this do?</h3>
<p>Prints a breadcrumb trail .</p>
<h3>How do I use it?</h3>
<p>Just insert the tag into your template/page like: <code>{breadcrumbs}</code></p>
<h3>What parameters does it take?</h3>
<p>
<ul>
<li><em>(optional)</em> <tt>delimiter</tt> - Text to seperate entries in the list (default ">>").</li>
<li><em>(optional)</em> <tt>initial</tt> - 1/0 If set to 1 start the breadcrumbs with a delimiter (default 0).</li>
<li><em>(optional)</em> <tt>root</tt> - Page alias of a page you want to always appear as the first page in
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>
<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>
<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 <a href> tags, otherwise it is added to the <span> tags.</li>
<li><em>(optional)</em> <tt>currentclassid</tt> - The CSS class for the <span> tag surrounding the current page name.</li>
<li><em>(optional)</em> <tt>starttext</tt> - Text to append to the front of the breadcrumbs list, something like "You are here".</li>
</ul>
