  12    ( from..to ... | upstream [ our-head ] )
  13
  14Prepare each commit with its patch since our-head forked from upstream,
  15one file per patch, for e-mail submission.  Each output file is
  16numbered sequentially from 1, and uses the first line of the commit
  17message (massaged for pathname safety) as the filename.
  18
  19When -o is specified, output files are created in that directory; otherwise in
  20the current working directory.
  21
  22When -n is specified, instead of "[PATCH] Subject", the first line is formatted
  23as "[PATCH N/M] Subject", unless you have only one patch.
  24
  25When --mbox is specified, the output is formatted to resemble
  26UNIX mailbox format, and can be concatenated together for processing
  27with applymbox.
