/** footnote2.php
* handle footnotes in a page
*
* AWColley 2007-08-05 -- created footnote.php
* Extracted from extendmarkup.php Version 2.0.59
* (see http://www.pmwiki.org/wiki/Cookbook/MarkupExtensions)
*
* 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.
