If var is specified, a variable whose name is the value of var is exported to the associated scope ( pageScope if no scope is specified).

If you use the setup frequently, it is more convenient to setup the tunnel as a Windows service . Assuming the name of the service is vnc_tunnel , the registry entry would look like:
Windows Registry Editor Version 5.00 [HKEY_...
