feat(group-layers): Add initial popcount scripts This script generates an entry in a text file for each time a derivation is referred to by another in nixpkgs. For initial testing, this output can be turned into group-layers compatible JSON with this trivial invocation: cat output \| awk '{ print "{\"" $2 "\":" $1 "}"}' \| jq -s '. \| add \| with_entries(.key \|= sub("/nix/store/[a-z0-9]+-";""))' > test-data.json 2019-08-11 19:10:03 +00:00			`#!/bin/bash`
