This is an interesting tool for computing minimal diffs, but the result is not very human friendly. If this is your goal and you are looking for something better than diff, have a look at graphtage: https://github.com/trailofbits/graphtage
I know, I wasn't trying to ignore or denigrate this purpose. It seemed apt to show a similar tool which still has a drastically different (and complementing) purpose, which is human readability.
Also works for XML, HTML, YAML and CSV.
