+/**
+ * @file
+ * Routing-script for the built-in PHP web server to enable basic support for
+ * clean URLs by faking the "q" query parameter as the main .htaccess would do.
+ *
+ * The built-in webserver should _only_ be used for development and test as it
+ * has a number of limitations that makes running Drupal on it highly insecure
+ * and somewhat limited.
+ *
+ * In particular be aware 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 webserver does not enforce any of the settings in .htacccess in
+ *     particular a remote user will be able to download files that normally
+ *     would be protected from direct access such as .module files.
+ *   - If clean urls is disabled on your site and you want to enable it from a
+ *     browser you have to access the administrative form via the clean-url
+ *     ( admin/config/search/clean-urls ) as the q=admin/... version of the form
+ *     tries to verify clean url support via a parallel request.
+ *
+ * Usage:
+ * php -S localhost:8888 .ht.router.php
+ *
+ * @see http://php.net/manual/en/features.commandline.webserver.php
