-"""This starts an SSH tunnel to a given host. If the SSH process ever dies then
-this script will detect that and restart it. I use this under Cygwin to keep
-open encrypted tunnels to port 25 (SMTP), port 143 (IMAP4), and port 110
-(POP3). I set my mail client to talk to localhost and I keep this script
-running in the background.
-
-Note that this is a rather stupid script at the moment because it just looks to
-see if any ssh process is running. It should really make sure that our specific
-ssh process is running. The problem is that ssh is missing a very useful
-feature. It has no way to report the process id of the background daemon that
-it creates with the -f command. This would be a really useful script if I could
-figure a way around this problem. """
