Instead of RetrieveAuthPage(), it may be better to use IncludeText.

If you want to extract from line 4 to the end for example, use this:

    function MarkupExcerpt($pagename) {
       $text = IncludeText($pagename, "$pagename lines=4..");
       return substr($text, 0, 200);
    }

You can also use "$pagename lines=4..6" if you want to only include lines 4,  
5 and 6 for example.

There are more than one ways to do it, if you want to define what will be  
shown from the page, you could wrap it with [[#exerpt]]...[[#excerptend]]  
and call the function RetrieveAuthSection($pagename, '#excerpt') instead of  
RetrieveAuthPage().
