This should probably be .config instead of config

The README says to see the nixb source for caveats, but I don't see caveats beyond --store not being supported on Darwin?

Also, nixb checks for the presence of a nix-builders.nix file and uses that to set up the builders config. If the file doesn't exist it just silently skips that, resulting in the only thing it actually doing is potentially setting --max-jobs 0. I see this repo has a nix-builders.nix file in it, but nixb isn't looking for that file. I assume this means that I need to either set the $NIX_BUILDERS_CONFIG var to point at it or copy it into ~/config/nix-builders.nix, but this isn't documented. What's the actual expected usage here?

On a related note, this nixb command wraps nix, but that means it's not actually usable with other tools that wrap nix (such as https://github.com/serokell/deploy-rs). It would be great if there was an alternative that just set the $NIX_CONFIG env var with the appropriate settings and then invoked whatever tool I asked it to. This way I could run e.g. with_nixb deploy to run deploy with $NIX_CONFIG set, and then nixb is really just shorthand for with_nixb nix "$@". Or maybe add a shell.nix that just sets this env var (and a corresponding devShells entry in the flake) so I can get a shell environment that uses it.
