32 input). By default, the file name is used as the patch name but this
33 can be overridden with the '--name' option. The patch can either be a
34 normal file with the description at the top or it can have standard
35 mail format, the Subject, From and Date headers being used for
36 generating the patch information. The command can also read series and
39 If a patch does not apply cleanly, the failed diff is written to the
