  10
  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.
  15
  16 When -o is specified, output files are created in that directory; otherwise in
  17 the current working directory.
  18
  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.
  21
  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.
