This repository currently works with Bazel 3. It might also work with Bazel 4 and even 5, but 7 is probably not going to work (try to disable bzlmod and try again but here be dragons).

If you just want to try the project, just enter the nix shell and run bazel build ....

PRs welcome if you figure out how to make it work with more recent Bazel versions / bzlmod. 😸

I give it a try by migrating to bzlmod
