This package just includes the agent component.

Nix is a purely functional package manager. This means that it treats packages like values in purely functional programming languages such as Haskell—they are built by functions that don't have side-effects, and they never change after they have been built. Nix stores packages in the Nix store, usually the directory /nix/store, where each package has its own unique sub-directory.
