/**
* Pages handler.
*
* This file dispatches pages. It is called via a URL rewrite in .htaccess
* from http://site/handler/page1/page2. The first element after site/ is
* the page handler name as registered by {@link elgg_register_page_handler()}.
* The rest of the string is sent to {@link page_handler()}.
*
* Note that the following handler names are reserved by elgg and should not be
* registered by any plugins:
* * action
* * cache
* * services
* * export
* * mt
* * xml-rpc.php
* * rewrite.php
* * tag (deprecated, reserved for backwards compatibility)
* * pg (deprecated, reserved for backwards compatibility)
*
* {@link page_handler()} explodes the pages string by / and sends it to
* the page handler function as registered by {@link elgg_register_page_handler()}.
* If a valid page handler isn't found, plugins have a chance to provide a 404.
*
* @package Elgg.Core
* @subpackage PageHandler
* @link http://docs.elgg.org/Tutorials/PageHandlers
