bgtunnel - Initiate SSH tunnels in the background
Useful when you need to connect to a database only accessible through
another ssh-enabled host. It works by opening a port forwarding ssh
connection in the background, using threads. The connection(s) are
automatically closed when the process exits, or when explicitly calling
the close
method of the returned SSHTunnelForwarderThread object.
