11 Prepare each commit with its patch since our-head forked from upstream,
12 one file per patch, for e-mail submission. Each output file is
13 numbered sequentially from 1, and uses the first line of the commit
14 message (massaged for pathname safety) as the filename.
16 When -o is specified, output files are created in that directory; otherwise in
17 the current working directory.
19 When -n is specified, instead of "[PATCH] Subject", the first line is formatted
20 as "[PATCH N/M] Subject", unless you have only one patch.
22 When --mbox is specified, the output is formatted to resemble
23 UNIX mailbox format, and can be concatenated together for processing
24 with applymbox.
