That's as much as I had worked out. Reading the guide suggested to me that
it wasn't ending because the channel was still open, so I started trying
to use channel.close in various places to make it close, but it never did
what I wanted it to do. I did get it to close & end the script, but
only before the result of "tail /var/log/messages" was output to the shell
(or browser, when run as a cgi script).  I didn't know where to begin,
when it came to adding an optional block of code, and didn't start because
I wasn't 100% that was what I needed to do.

Any clues anyone, please ? I'm going to have a go at working out what I
should do, but would greatly appreciate the answer from
someone who knows :-)
