6 USAGE='[-n | -k] [-o <dir> | --stdout] [--signoff] [--check] [--diff-options] [--attach] <his> [<mine>]'
7 LONG_USAGE='Prepare each commit with its patch since <mine> head forked from
8 <his> head, one file per patch formatted to resemble UNIX mailbox
9 format, for e-mail submission or use with git-am.
11 Each output file is numbered sequentially from 1, and uses the
12 first line of the commit message (massaged for pathname safety)
15 When -o is specified, output files are created in <dir>; otherwise
16 they are created in the current working directory. This option
17 is ignored if --stdout is specified.
19 When -n is specified, instead of "[PATCH] Subject", the first
20 line is formatted as "[PATCH N/M] Subject", unless you have only
23 When --attach is specified, patches are attached, not inlined.'
