/**
* @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
