33 input). By default, the file name is used as the patch name but this
34 can be overridden with the '--name' option. The patch can either be a
35 normal file with the description at the top or it can have standard
36 mail format, the Subject, From and Date headers being used for
37 generating the patch information. The command can also read series and
