   3   * This overwrites DOKU_CONF. Each animal gets its own configuration and data directory.
   4   * This can be used together with preload.php. See preload.php.dist for an example setup.
   5   * For more information see http://www.dokuwiki.org/farms.
   6   *
   7   * The farm directory (constant DOKU_FARMDIR) can be any directory and needs to be set.
   8   * Animals are direct subdirectories of the farm directory.
   9   * There are two different approaches:
  10   *  * An .htaccess based setup can use any animal directory name:
  11   *    http://example.org/<path_to_farm>/subdir/ will need the subdirectory '$farm/subdir/'.
  12   *  * A virtual host based setup needs animal directory names which have to reflect
  13   *    the domain name: If an animal resides in http://www.example.org:8080/mysite/test/,
  14   *    directories that will match range from '$farm/8080.www.example.org.mysite.test/'
  15   *    to a simple '$farm/domain/'.
