[4/9,final,act] Add replace-spdx-license.sh script
Commit Message
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.
