* `show-duplication.pl', a small utility that shows the amount of
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).
$ ./show-duplication.pl /nix/var/nix/profiles/default

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