Sounds perfect.

Yes, this is exactly the kind of thing I was thinking of - fast work!
So, to be clear, would FreeGuide need to use --list-providers to get the
providers, then ask the user what provider, and then use --list-channels to get
the channels and make a config file? Any ideas on how to make this general so
I don't have to write specific code for each grabber?
Can I still use --output on both these options?
How about giving default values for the other options in the output too?
(Obviously then the name --list-channels becomes wrong - maybe --configure
--non-interactive as I said in the other email?)

The above would solve this though wouldn't it?

Thinking about this, I don't think it's right. I don't want my program to
interact with the grabbers except using commandline arguments. The reason for
this is that I want the user to be able to plug in any other grabber that gets
written without needing major rewrites of my code or requiring loads of
specific things from the grabber writer.
In summary, the ability to dump all the possible channels from tv_grab_uk would
solve my problem (and I can submit a patch to do this when I get a chance), and
the providers problem in tv_grab_na is causing me headaches at the moment
because I can't see how to get round it without writing specific code in
FreeGuide.
I'll think on...
