Yes, and even if it's old, it is a really well done tutorial to understand the
internals of git. I read it after gittutorial and gittutorial-2. It's just
that I was surprised to learn about this command, "much more powerful" than
git-log. To me it looked a lot like git log --raw, and I found git log -p
more useful, so I was wondering what I was missing until I read the source
to see that nowadays the two commands were mostly the same.

Well in this case you can say that the intent was successful since it made
me read the source code ;)
