6 USAGE='[-n | -k] [-o <dir> | --stdout] [--signoff] [--check] [--mbox] [--diff-options] <upstream> [<our-head>]'
7 LONG_USAGE='Prepare each commit with its patch since our-head forked from upstream,
8 one file per patch, for e-mail submission. Each output file is
9 numbered sequentially from 1, and uses the first line of the commit
10 message (massaged for pathname safety) as the filename.
12 When -o is specified, output files are created in that directory; otherwise in
13 the current working directory.
15 When -n is specified, instead of "[PATCH] Subject", the first line is formatted
16 as "[PATCH N/M] Subject", unless you have only one patch.
18 When --mbox is specified, the output is formatted to resemble
19 UNIX mailbox format, and can be concatenated together for processing
23 # Force diff to run in C locale.
