<h4>Features</h4>
<ul>
<li>Highlight sources of any language</li>
<li>automatically, server-side (no javascripts)</li>
<li>XHTML-Compliant, <code><div></code>, <code><ul></code>, <code><span></code> with class-attributes and a css-file are used for styling    </li>
<li>optionally add a heading for every code-block</li>
<li>optionally specify line-number offset (BREAKS XHTML COMPLIANCE)</li>
<li>optionally don’t display line-numbers</li>
<li>set per-codeblock if the code is html_entity_encoded or not</li>
<li>only parses <code><pre></code>-tags with the <code>lang=</code>-attribute, thus does not interfere with any regular preformatted contents you might have</li>
<li>degrades beautifully through <code><pre></code>-tags (if you keep the sources clean, that is)</li>
<li>all settings through logical, valid arguments for the main container</li>
<li>comes with generic cross-browser CSS (tested: IE5.5+, FF, Safari, Opera)</li>
</ul>
<h4>Version History</h4>
<ul>
<li>1.3: Thanks to a tipp now the link-path to the stylesheets is correct, sorry for the inconvenience</li>
<li>1.2: Leading whitespace isn’t stripped anymore (indents as well as newlines), when there’s no title the title-div is not being generated anymore</li>
<li>1.1: Solved the issue with single-quotes being changed to typographical quotes</li>
</ul>
<h4>Known Issues</h4>
<p>While the plugin is basically XHTML 1.0 Strict compliant there’s just no way of getting the offset-based line-numbering to display without inadequate (ab)use of javascript and css hacks, so be warned that <em>IF you use the line-number offset, your documents will <strong>NOT</strong> validate</em> because of the forbidden <code>start=</code>-attribute for the <code><ol></code>!</p>
