=====Backlinks Handler=====

<<This feature was implemented in the 1.1.6.2. release<<>>==See also:==
Documentation: BacklinksHandlerInfo.>>
This is the development page for the backlinks handler.

Nothing more than a couple of minor modifications to the WakkaBacklinksHandler. 
The handler shows a **list of pages linking to the current page**. 
Given the strong page-dependence of this function, I think it makes more sense to have it work as a //handler// than an //action//. 

To install it just save the code block below as ##handlers/page/backlinks.php##
Use it as any other handler, appending ##/backlinks## to the page URL.
__Note__: the backlinks handler is available for testing on this server.

%%(php)

<div class="page">
<?php
/**
* Displays a list of internal pages linking to the current page.
*
* Usage: append /backlinks to the URL of the page
* 
* This handler retrieves a list of internal pages linking to the current page.
* It first checks if they exist and prints them on the screen.

* @package Handlers
