* 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
