Subject: [PATCH 1/1] scripts/gen_sendmail.py: Script Added: Generate git send-email arguments automatically!
I guess this script won't be merged upstream, but I think it could be useful for someone else.
Description borrowed from the header:
---------------
!# This script generates the git send-email automatically
!# by looking at the output generated by scripts/get_maintainer.pl
!#
!# You can pass as many patch files as needed.
!# Usage: python send-mail.py [option] <patch1> <patch2> ...
Example of use:
Passed as arguments one patch file and -v (verbose mode).
---------------
