  10
  11Prepare each commit with its patch since our-head forked from upstream,
  12one file per patch, for e-mail submission.  Each output file is
  13numbered sequentially from 1, and uses the first line of the commit
  14message (massaged for pathname safety) as the filename.
  15
  16When -o is specified, output files are created in that directory; otherwise in
  17the current working directory.
  18
  19When -n is specified, instead of "[PATCH] Subject", the first line is formatted
  20as "[PATCH N/M] Subject", unless you have only one patch.
  21
  22When --mbox is specified, the output is formatted to resemble
  23UNIX mailbox format, and can be concatenated together for processing
  24with applymbox.
