 # Command for sending a collection of Mercurial changesets as a series
 # of patch emails.
 #
 # The series is started off with a "[PATCH 0 of N]" introduction,
 # which describes the series as a whole.
 #
 # Each patch email has a Subject line of "[PATCH M of N] ...", using
 # the first line of the changeset description as the subject text.
 # The message contains two or three body parts:
 #
 #   The remainder of the changeset description.
 #
 #   [Optional] If the diffstat program is installed, the result of
 #   running diffstat on the patch.
 #
 #   The patch itself, as generated by "hg export".
 #
 # Each message refers to all of its predecessors using the In-Reply-To
 # and References headers, so they will show up as a sequence in
 # threaded mail and news readers, and in mail archives.
 #
 # For each changeset, you will be prompted with a diffstat summary and
 # the changeset summary, so you can be sure you are sending the right
 # changes.
 #
 # To enable this extension:
 #
 #   [extensions]
 #   hgext.patchbomb =
 #
 # To configure other defaults, add a section like this to your hgrc
 # file:
 #
 #   [email]
 #   from = My Name <my@email>
 #   to = recipient1, recipient2, ...
 #   cc = cc1, cc2, ...
 #   bcc = bcc1, bcc2, ...
 #
 # Then you can use the "hg email" command to mail a series of changesets
 # as a patchbomb.
 #
 # To avoid sending patches prematurely, it is a good idea to first run
 # the "email" command with the "-n" option (test only).  You will be
 # prompted for an email recipient address, a subject an an introductory
 # message describing the patches of your patchbomb.  Then when all is
 # done, your pager will be fired up once for each patchbomb message, so
 # you can verify everything is alright.
 #
 # The "-m" (mbox) option is also very useful.  Instead of previewing
 # each patchbomb message in a pager or sending the messages directly,
 # it will create a UNIX mailbox file with the patch emails.  This
 # mailbox file can be previewed with any mail user agent which supports
 # UNIX mbox files, i.e. with mutt:
 #
 #   % mutt -R -f mbox
 #
 # When you are previewing the patchbomb messages, you can use `formail'
 # (a utility that is commonly installed as part of the procmail package),
 # to send each message out:
 #
 #  % formail -s sendmail -bm -t < mbox
 #
 # That should be all.  Now your patchbomb is on its way out.
