11 | Prepare each commit with its patch since our-head forked from upstream, | |
12 | one file per patch, for e-mail submission. Each output file is | |
13 | numbered sequentially from 1, and uses the first line of the commit | |
14 | message (massaged for pathname safety) as the filename. | |
15 | ||
16 | When -o is specified, output files are created in that directory; otherwise in | |
17 | the current working directory. | |
18 | ||
19 | When -n is specified, instead of "[PATCH] Subject", the first line is formatted | |
20 | as "[PATCH N/M] Subject", unless you have only one patch. | |
5c2c972f JH |
21 | |
22 | When --mbox is specified, the output is formatted to resemble | |
23 | UNIX mailbox format, and can be concatenated together for processing | |
24 | with applymbox. | |
