I had already done this in PERL, but, even though we have PERL, we
are not allowed to download modules here. So, I'm redoing it in
Expect. I thought someone would say a "oh just <blah, blah> and
you're done" type of response.
Well, what you're doing right here is reimplementing rancid. Which is
wholly unnecessary because we already have rancid, and a more modern
alternative named oxidized. And you've gotten that response already.
Fine as a personal exercise, of course. The inability to download
modules seems sadistic to me, though.
