-----------------------------+-------------------
 In Tails' automated test suite we have plans to use Chutney to run a
 simulated Tor network (for increased performance and, in particular,
 robustness). Of course, we do not want to run that Chutney instance in the
 system under testing (i.e. the Tails instance) but on the host
 orchestrating the tests. In order to avoid having to forward traffic via
 firewall rules, we'd like it to be possible to make the Chutney hosts
 listen on some other IP address than localhost.

 The attached patch allows setting the address all Chutney hosts will
 listen on via the `CHUTNEY_LISTEN_ADDRESS` environment variable.
