-This file handles a rather silly use case:

-wisdom, you bound the SCGI ports of the rtorrent instances on server B to
-localhost, leaving Aberrant unable to query them. Rtorrent won't allow you
-to rebind the SCGI port while it's running, and you don't want to restart
-the rtorrent instance(s) because restarting stuff sucks. Therefore, you
-need another way for Aberrant to communicate to them.
-
-This script acts as a proxy to the rtorrent instances on server B. It will
-listen on a port (don't forget to open the port in your iptables), and
-relay all data it receives to the torrent SCGI port and vice versa.

-Configure `port_mapping` in the form `listen_port`: `rtorrent_port`.
