echo >&2 "usage: $0"' [-n] [-o dir] [-<diff options>...] upstream [ our-head ] |
|
|
|
Prepare each commit with its patch since our-head forked from upstream, |
|
one file per patch, for e-mail submission. 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 that directory; otherwise in |
|
the current working directory. |
|
|
|
When -n is specified, instead of "[PATCH] Subject", the first line is formatted |
|
as "[PATCH N/M] Subject", unless you have only one patch. |
