* `nix-store -q --tree' shows a tree representing the dependency graph
  of the given derivation.  Useful for getting a quick overview of how
  something was built.  E.g., to find out how the `baffle' program in
  your user environment was built, you can do

    $ nix-store -q --tree $(nix-store -qd $(which baffle))

  Tree nesting depth is minimised (?) by topologically sorting paths
  under the relation A < B iff A \in closure(B).
