+ *	Extracted from extendmarkup.php Version 2.0.59

+ *
+ *	Copyright 2007 A. W. Colley
+ *	You may use this file however you see fit. I don't care.
+ *
+ *	Modified by Randy Brown to work with PHP 5.5 and to omit the blue line if no 
+ *	footnote is on the page. This allows a group footer to include [^#^] to show 
+ *	any footnotes present, without showing a blue line if there are none.
