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.
