@itsalaidbacklife make sure you test this backwards and forwards. I used a special command to get the file tree of the repo before generating this file, so it's based off the files we have declared today.

git ls-tree -r HEAD --name-only | sed -n 's/..*\.//p' | sort | uniq -c | sort -nr

Which gives something like this:
