+Usage: ${myname} <src_dir> <dst_dir> <base> <inc> [sed_re]
+ Renumbers all patches found in 'src_dir', starting at 'base', with an
+ increment of 'inc', and puts the renumbered patches in 'dst_dir'.
+ Leading digits are replaced with the new indexes, and a subsequent '_'
+ is replaced with a '-'.
+ If 'sed_re' is given, it is interpreted as a valid sed expression, and
+ is be applied to the patch name.
+ If the environment variable FAKE is set to 'y', then nothing gets done,
+ the command to run is only be printed, and not executed (so you can
+ check beforehand).
+ 'dst_dir' must not yet exist.
+ Eg.:
+ patch-renumber.sh patches/gcc/4.2.3 patches/gcc/4.2.4 100 10
+ patch-renumber.sh /some/dir/my-patches patches/gcc/4.3.1 100 10 's/(all[_-])*(gcc[-_])*//;'
