License change

Since I noticed the repo is transitioning from the filth called GPL to something more open, I want my contributions relicensed as well. Hence > To the maintainers of [[q60/rot13 Github repository]](https://github.com/q60/rot13), > > I, George Endo (GitHub handle @wtlgo), confirm that I am the sole copyright holder of all code, documentation, and other creative works I have contributed to this repository. Effective 2 May 2025, I grant you and all downstream users an irrevocable, worldwide, royalty-free licence to use, modify, distribute, and sublicense my contributions. > > My preference is that you apply the MIT License to my contributions. However, I also grant permission for them to be redistributed under the Unlicense if that better suits the project. This permission supersedes the previous GPLv2.0-only licence that applied to my contributions and applies retroactively to every commit I have made and prospectively to any future contributions I may choose to submit. > > Signed, > George Endo > GitHub: @wtlgo > Date: 2 May 2025
