This script is to replace an SPDX license ID by another one.
I.e, it's to perform an actual re-licensing of a given file.

A way to use the script is this:

    replace-spdx-license.sh  --from LGPL-3.0-or-later \
			      --to  "Apache-2.0 WITH LLVM-exception" \
			      some-file-to-relicense.cc

	* relicensing-scripts/replace-spdx-license.sh: New script.

Applied, thanks.  It's going to show up in the v3 set of patches.  Until
then you can see this in the relicensing branch that can be browsed at
https://sourceware.org/git/?p=libabigail.git;a=shortlog;h=refs/heads/relicensing.

Cheers,

I have updated the licensing branch accordingly!
