* [*] NOTE: Beginning from version 0.1.0 rtpg can use direct connec- *
* tion to rtorrent SCGI-port/socket. You can leave out this step and *
* point to rtorrent's SCGI-port in your /etc/rtpg/rtpg.conf. So      *
* comment VirtualHost with name 'rtpg-scgi.localhost' in your        *
* /etc/apache2/sites-available/rtpg.apache.conf.                     *
*                                                                    *

See /usr/share/doc/rtpg-www/examples/rtorrent.rc for configure
your rtorrent. RTPG uses file /etc/rtpg/rtpg.conf as config
by default.
