/**
 * This overwrites DOKU_CONF. Each animal gets its own configuration and data directory.
 * This can be used together with preload.php. See preload.php.dist for an example setup.
 * For more information see http://www.dokuwiki.org/farms.
 *
 * The farm directory (constant DOKU_FARMDIR) can be any directory and needs to be set.
 * Animals are direct subdirectories of the farm directory.
 * There are two different approaches:
 *  * An .htaccess based setup can use any animal directory name:
 *    http://example.org/<path_to_farm>/subdir/ will need the subdirectory '$farm/subdir/'.
 *  * A virtual host based setup needs animal directory names which have to reflect
 *    the domain name: If an animal resides in http://www.example.org:8080/mysite/test/,
 *    directories that will match range from '$farm/8080.www.example.org.mysite.test/'
 *    to a simple '$farm/domain/'.
