Let's watch this for v4 to properly embed the version in flake.nix. Will want it to be dynamic via GitHub action instead of hard coding the version.

[EDIT] added note to https://github.com/klmcwhirter/envycontrol/blob/tests/V4_Roadmap.md

I didn't catch this earlier, but FWIW Nix flakes are useful on more than just NixOS. They call their package manager Nix as well (overloaded term). I used it on Fedora and in an Ubuntu VM a year or so ago.

I was experimenting with nix develop using project specific flakes that would install everything needed for that project (e.g., tinygo, emscripten, python complied with wasi support, etc.) so I did not have to install the superset of the tools I use across all the projects I periodically work. Was kind of neat.

But the point is that the flake.nix could be useful on even macOS.
