Would you be willing to tell me how, in such a script, I could detect the
presence or absence of a specific header, say "Exception: norm"? (I don't
intend or want to enter the currently raging header debate. I'm just asking a
specific technical question.)
Heh. Any header is available via %{header}, so it would be something like:
scan -format '%{exception}' message
Would output the value of any "Exception" header. You can use -file to
scan something that's not in a MH folder.
You could do something more complicated in the format script, but maybe
it might be better to do that in the script. Anyway, you get the idea;
think of scan as "generic tool to interrogate message headers". Not that
it's necessarily wrong to use sed, but I think it might be hard to handle
things like header folding (but not impossible) or character set conversion.
