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