+NAME
+----
+tor-fw-helper - Manage upstream firewall/NAT devices
+
+SYNOPSIS
+--------
+**tor-fw-helper** [-h|--help] [-T|--test] [-v|--verbose] [-g|--fetch-public-ip]
+-i|--internal-or-port __TCP port__ [-e|--external-or-port _TCP port_]
+[-d|--internal-dir-port _TCP port_] [-p|--external-dir-port _TCP port_]
+
+DESCRIPTION
+-----------
+**tor-fw-helper** currently supports Apple's NAT-PMP protocol and the UPnP
+standard for TCP port mapping. It is written as the reference implementation of
+tor-fw-helper-spec.txt and conforms to that loose plugin API.  If your network
+supports either NAT-PMP or UPnP, tor-fw-helper will attempt to automatically
+map the required TCP ports for Tor's Or and Dir ports. +
+
+OPTIONS
+-------
+**-h** or **--help**::
+    Display help text and exit.
+
+**-v**::
+    Display verbose output.
+
+**-T** or **--test**::
+    Display test information and print the test information in
+    tor-fw-helper.log
+
+**-g** or **--fetch-public-ip**::
+    Fetch the the public ip address for each supported NAT helper method.
+
+**-i** or **--internal-or-port** __port__::
+    Inform **tor-fw-helper** of your internal OR port. This is the only
+    required argument.
+
+**-e** or **--external-or-port** __port__::
+    Inform **tor-fw-helper** of your external OR port.
+
+**-d** or **--internal-dir-port** __port__::
+    Inform **tor-fw-helper** of your internal Dir port.
+
+**-p** or **--external-dir-port** __port__::
+    Inform **tor-fw-helper** of your external Dir port.
+
+BUGS
+----
+This probably doesn't run on Windows. That's not a big issue, since we don't
+really want to deal with Windows before October 2010 anyway.
