| ( from..to ... | 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. |
| |
| When --mbox is specified, the output is formatted to resemble |
| UNIX mailbox format, and can be concatenated together for processing |
| with applymbox. |
