index.php

<?php

/**
 * index.php is meant to setup basic library lookup paths as well as
 * load the configuration. After the setup is done the request will
 * be handled and forwarded to the respective controller.
 *
 * Lunr's preferred Controller setup uses URL based controller, method
 * and parameter definitions. From the client (browser) side this could
 * look like this:
 *
 *  http://www.example.org/controller/method/parameter1/parameter2/....
 *
 * URL rewriting rules (for apache, lighttpd, etc) should take care of
 * transforming the URL to something resembling this pattern:
 *
 *  http://www.example.org/index.php?controller=controller&method=method&param1=parameter1&....
 *
 * This makes those values available from PHP over the $_GET super global.
