package duplication present in (e.g.) a profile. It shows the
number of instances of each package in a closure, along with the
size in bytes of each instance as well as the "waste" (the
difference between the sum of the sizes of all instances and the
average size).

This utility is useful for measuring the cost in terms of disk space
of the Nix approach.
