flakes

To enable:

mkdir ~/.config/nix
echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf

The blog article I'm reading has a link to the NixOS wiki page

I'm in a directory with a flake, and now:

$ nix flake show
git+file:///Users/llimllib/somedir/main?ref=refs%2fheads%2fmain&rev=2245bf45a150fce882aa4070b6929b4992c2d0fc

I don't really understand what this is telling me? but ok
