/**
 * Example of how to create a custom article editing form.
 * Created July 2006.
 *
 * By Barry Brannan (http://www.mediawiki.org/wiki/User:Barrylb)
 *
 * This example assumes you have a set of articles named Person/John_Smith, Person/John_Brown ... etc
 *
 * Whenever you are editing an article named Person/*, a form is shown with fields Sex, Age, Description.
 * When you first create the article, the fields are put together with a template named Person, eg:
 *   {{Person|sex=M|age=60}}My description
 * When you next edit the article, this form extracts the fields from the text and allows the user to
 * edit them.
 *
 * You also need to create a template called [[Template:Person]] to display the fields as you would like.
 * To enable this extension place the following in LocalSettings.php:
 *     require_once("extensions/CustomEdit.php");
 *
 * This example is released to the public domain.
