Well its not really a tool. Its an overarching system/philosophy, within which there are tools that you can use. Unfortunately the naming muddies that a bit, when people (who usually are newer and so aren't as familiar with the distinctions) use nix to mean the ecosystem, the language, the package manager, or the OS distribution interchangeably.
