I also like ways of getting such reports. Now there can be made some
tricks with the output of nix-store queries, am I right?

Regarding these optimization problems we are dealing with... I'd like
to note that I liked 'nix' a lot because I wanted to get all away from
the "dynamic libraries mess". Before knowing 'nix', all I could desire
was a linux distribution with all binaries statically compiled. So
imagine how much I don't care about the increased memory or hd usage,
if I never again have to take care of dynamic libraries problems. Of
course 'nix' looked to me like a much better approach (and easier)
than having a distro with all binaries statically compiled. Its great
nix-store allows a lot of control on what's on the store, IMO.
