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