+/**
+* Arc90's Readability ported to PHP for FiveFilters.org
+* Based on readability.js version 1.7.1 (without multi-page support)
+* ------------------------------------------------------
+* Original URL: http://lab.arc90.com/experiments/readability/js/readability.js
+* Arc90's project URL: http://lab.arc90.com/experiments/readability/
+* JS Source: http://code.google.com/p/arc90labs-readability
+* Ported by: Keyvan Minoukadeh, http://www.keyvan.net
+* More information: http://fivefilters.org/content-only/
+* License: Apache License, Version 2.0
+* Requires: PHP5
+* Date: 2010-10-29
+*
+* Differences between the PHP port and the original
+* ------------------------------------------------------
+* Arc90's Readability is designed to run in the browser. It works on the DOM
+* tree (the parsed HTML) after the page's CSS styles have been applied and
+* Javascript code executed. This PHP port does not run inside a browser.
+* We use PHP's ability to parse HTML to build our DOM tree, but we cannot
+* rely on CSS or Javascript support. As such, the results will not always
+* match Arc90's Readability. (For example, if a web page contains CSS style
+* rules or Javascript code which hide certain HTML elements from display,
+* Arc90's Readability will dismiss those from consideration but our PHP port,
+* unable to understand CSS or Javascript, will not know any better.)
+*
+* Another significant difference is that the aim of Arc90's Readability is
+* to re-present the main content block of a given web page so users can
+* read it more easily in their browsers. Correct identification, clean up,
+* and separation of the content block is only a part of this process.
+* This PHP port is only concerned with this part, it does not include code
+* that relates to presentation in the browser - Arc90 already do
+* that extremely well, and for PDF output there's FiveFilters.org's
+* PDF Newspaper: http://fivefilters.org/pdf-newspaper/.
+*
+* Finally, this class contains methods that might be useful for developers
+* working on HTML document fragments. So without deviating too much from
+* the original code (which I don't want to do because it makes debugging
+* and updating more difficult), I've tried to make it a little more
+* developer friendly. You should be able to use the methods here on
+* existing DOMElement objects without passing an entire HTML document to
+* be parsed.
+*/
+
+// This class allows us to do JavaScript like assignements to innerHTML
+require_once(dirname(__FILE__).'/JSLikeHTMLElement.php');
+
+// Alternative usage (for testing only!)
+// uncomment the lins below and call Readability.php in your browser
+// passing it the URL of the page you'd like content from, e.g.:
+// Readability.php?url=http://medialens.org/alerts/09/090615_the_guardian_climate.php
+
+/*
+if (!isset($_GET['url']) || $_GET['url'] == '') {
+        die('Please pass a URL to the script. E.g. Readability.php?url=bla.com/story.html');
+}
+$url = $_GET['url'];
+if (!preg_match('!^https?://!i', $url)) $url = 'http://'.$url;
+$html = file_get_contents($url);
+$r = new Readability($html, $url);
+$r->init();
+echo $r->articleContent->innerHTML;
