|
|
* 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.
