Reformatted excerpts from Scott Henson's message of 2010-01-03:

No. Mutt is quite good at this, actually. If you do move them, you will
have to update the Sup index to reflect the new source.

The easiest thing would be to make a dump of the message state with
sup-dump, and then sup-sync -c --restore <dumpfile> on both sources.
Of course, check first to make sure this works!

That incurs a silly amout of redundant work, so you could also consider
the fancier way of just updating the source_id in the index, using the
console.

The hooks are just ruby at the moment. I'm not convinced a DSL would be
an improvement. For example, my before-add hook looks like this:

  to_string = message.recipients.map { |t| t.email }.join(" ")
  case to_string
  when /\bgit@vger.kernel.org\b/
    message.add_label :git
    message.remove_label :inbox
  when /\bsup-(devel|talk)@rubyforge.org\b/
    message.add_label :sup
  when /\bditz-talk@rubyforge.org\b/
    message.add_label :ditz
  [...]

Apart from the first line, it seems pretty DSL-like already to me.  But
try it, if you like, and report back if you come up with something nice.
