17 Usage: ${myname} <src_dir> <dst_dir> <base> <inc> [sed_re]
18 Renumbers all patches found in 'src_dir', starting at 'base', with an
19 increment of 'inc', and puts the renumbered patches in 'dst_dir'.
20 Leading digits are replaced with the new indexes, and a subsequent '_'
21 is replaced with a '-'.
22 If 'sed_re' is given, it is interpreted as a valid sed expression, and
23 is be applied to the patch name.
24 If the environment variable FAKE is set to 'y', then nothing gets done,
25 the command to run is only be printed, and not executed (so you can
27 'dst_dir' must not yet exist.
