[PATCH] Add git-send-email-script - tool to send emails from git-format-patch-script
This is based off of GregKH's script, send-lots-of-email.pl, and strives to do all the nice things a good subsystem maintainer does when forwarding a patch or 50 upstream: All the prior handlers of the patch, as determined by the Signed-off-by: lines, and/or the author of the commit, are cc:ed on the email. All emails are sent as a reply to the previous email, making it easy to skip a collection of emails that are uninteresting. Signed-off-by: Ryan Anderson <ryan@michonline.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
