Usage: ${myname} <src_dir> <dst_dir> <base> <inc> [sed_re]
yann@1622
    18
    Renumbers all patches found in 'src_dir', starting at 'base', with an
yann@1622
    19
    increment of 'inc', and puts the renumbered patches in 'dst_dir'.
yann@1622
    20
    Leading digits are replaced with the new indexes, and a subsequent '_'
yann@1622
    21
    is replaced with a '-'.
yann@1608
    22
    If 'sed_re' is given, it is interpreted as a valid sed expression, and
yann@1622
    23
    is be applied to the patch name.
yann@1622
    24
    If the environment variable FAKE is set to 'y', then nothing gets done,
yann@1622
    25
    the command to run is only be printed, and not executed (so you can
yann@1622
    26
    check beforehand).
yann@1622
    27
    'dst_dir' must not yet exist.
