I was responding to this paragraph in Johannes' message
Note the exception? For new Rust code (and of course excluding code
that has been ported verbatim from GPLv2-licensed code), GPL v2
could be used with an exception along these lines: This file is
licensed under the GPL v2, with the exception that it can be freely
used in the Gitoxide project.
That suggestion is pretty close to what libgit2 has in its
git.git-authors file[1]. I'm not sure how practical it is to special
case just one project though.
Thanks
Phillip
