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 There are three output modes. By default, output files are created in
13 the current working directory; when -o is specified, they are created
14 in that directory instead; when --stdout is specified, they are spit
15 on standard output, and can be piped to git-am.
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
25 # Force diff to run in C locale.
