	# find the modules/folders with highest number of changes
	git rev-list --objects --all \| awk '$2' \| sort -k2 \| uniq -cf1 \| sort -rn \| head

	# find the files with the highest number of changes
	git rev-list --objects --all \| awk '$2' \| sort -k2 \| uniq -cf1 \| sort -rn \|
	while read frequency sample path
	do
	[ "blob" == "$(git cat-file -t $sample)" ] && echo "$frequency\t$path";
	done
