echo >&2 "usage: $0"' [-n] [-o dir | --stdout] [--keep-subject] [--mbox] [--check] [--signoff] [-<diff options>...] upstream [ our-head ]
Prepare each commit with its patch since our-head forked from upstream,
one file per patch, for e-mail submission. Each output file is
numbered sequentially from 1, and uses the first line of the commit
message (massaged for pathname safety) as the filename.
When -o is specified, output files are created in that directory; otherwise in
the current working directory.
When -n is specified, instead of "[PATCH] Subject", the first line is formatted
as "[PATCH N/M] Subject", unless you have only one patch.
When --mbox is specified, the output is formatted to resemble
UNIX mailbox format, and can be concatenated together for processing
with applymbox.
