+ o Major features:
+ - Tor now has the ability to wrangle NAT devices like a good network cowbot
+ with the tor-fw-helper tool. The tor-fw-helper tool supports Apple's
+ NAT-PMP protocol and the UPnP standard for TCP port mapping. This
+ optional tool may be enabled at compile time by configuring with
+ '--enable-upnp' or '--enable-natpmp' or with both. This tool may be
+ called by hand or by Tor. By configuring the PortForwarding option, Tor
+ will launch the helper on a regular basis to ensure that the NAT mapping
+ is regularly updated. Additionally, a user may also specify an
+ alternative helper by using the PortForwardingHelper option. The helper
+ may be specified by name or with the full path to the helper. The default
+ helper is named 'tor-fw-helper' and any alternative helper must take the
+ tor-fw-helper-spec.txt into account.
