404 page

First, a wrapper for every page, root/page.tt:

<html>
<head>
  <title>[% (title || "KitiWiki") | html %]</title>
  <link rel="stylesheet" type="text/css" href="[%base%]static/main.css" />
</head>
<body>
[% IF c.flash.message %]
<p class="message">[% c.flash.message | html %]</p>
[% END %]
[% content %]
</body>
</html>

Then 404.tt

[% WRAPPER page.tt title = "404 Not Found" %]
<h1>404 Not Found</h1>
<a href="[% c.uri_for('/') | html %]">Go home</a>
[% END %]
