<?php

/**
* Display a simplified 'Recent Changes' listing.

* This action is intended for inclusion (for example) on the Home page to show a very simple listing of recently changed pages,

*
* Based on RecentChangesPlus by FernandoBorcel
*
* @package    Actions
* @name    changesteaser.php

* @usage   {{changesteaser}} or specify number of pages to show {{changesteaser max="5"}}
