The files in this directory were contributed by users of MH.  It's a
place for scripts (shell, perl, etc.), format files, and other useful
MH stuff contributed by users.

Jerry Peek has agreed to manage this area (as he has time).
Please send contributions to jpeek@jpeek.com.  He writes:

  I've agreed to accept contributions from people and put them into the
  archive every month or so. To start, I'm going to try to do a little
  filtering, to weed out stuff that MH can already handle.  For instance,
  if someone sends a script that uses "grep" to find messages, and the MH
  "pick" command can do the same thing, I'll probably send it back with
  an explanation.  I won't be very picky, though.  I *won't* test
  contributions thoroughly or "approve" them.  Send me contributions,
  comments, flames, etc.  Thanks.

So, these files have not necessarily been tested.  They are not
supported and there is no guarantee that they'll do what you want.
Please report bugs in the scripts directly to their authors, not
to the MH bug reporting address.  Use at your own risk, etc.
