/**
* Forwarder/Router to doku.php
*
* In normal usage, this script simply redirects to doku.php. However it can also be used as a routing
* script with PHP's builtin webserver. It takes care of .htaccess compatible rewriting, directory/file
* access permission checking and passing on static files.
*
* Usage example:
*
* php -S localhost:8000 index.php
*
