# Interactive script 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.
# It is best to run this script with the "-n" (test only) flag before
# firing it up "for real", in which case it will use your pager to
# display each of the messages that it would send.
# To configure a default mail host, add a section like this to your
# hgrc file:
# [smtp]
# host = my_mail_host
# port = 1025
# tls = yes # or omit if not needed
# username = user     # if SMTP authentication required
# password = password # if SMTP authentication required - PLAINTEXT
# To configure other defaults, add a section like this to your hgrc
# file:
# [patchbomb]
# from = My Name <my@email>
# to = recipient1, recipient2, ...
# cc = cc1, cc2, ...
