/**
 * @file
 * Router script for the built-in PHP web server.
 *
 * The built-in web server should only be used for development and testing as it
 * has a number of limitations that makes running Drupal on it highly insecure
 * and somewhat limited.
 *
 * Note that:
 * - The server is single-threaded, any requests made during the execution of
 *   the main request will hang until the main request has been completed.
 * - The web server does not enforce any of the settings in .htaccess in
 *   particular a remote user will be able to download files that normally would
 *   be protected from direct access such as .module files.
 *
 * The router script is needed to work around a bug in PHP, see
 * https://bugs.php.net/bug.php?id=61286.
 *
 * Usage:
 * php -S localhost:8888 .ht.router.php
 *
 * @see http://php.net/manual/en/features.commandline.webserver.php
