For example, if the top-level flake depends on "nixpkgs/release-19.03", and one of its dependencies depends on "nixpkgs", then the latter will be mapped to "nixpkgs/release-19.03", rather than whatever the default branch of "nixpkgs" is. Thus you get only one "nixpkgs" dependency rather than two. This currently only works in a breadth-first way, so the other way around (i.e. if the top-level flake depends on "nixpkgs", and a dependency depends on "nixpkgs/release-19.03") still results in two "nixpkgs" dependencies.
Nix, the purely functional package manager
Nix is a new take on package management that is fairly unique. Because of its purity aspects, a lot of issues found in traditional package managers don't appear with Nix.
To find out more about the tool, usage and installation instructions, please read the manual, which is available on the Nix website at http://nixos.org/nix/manual.
