I published another tutorial on Git today, this one describing the  
system from a "bottom up" perspective.  I know it's been written about  
this way before, but I was aiming at a bit more thoroughness, and a  
paced introduction to the basics.

There's a link to the PDF is in the following blog post:

  http://www.newartisans.com/blog_files/git.from.bottom.up.php

In addition to what was mentioned before me:

On page 6, instead of `git show --pretty=format:%T HEAD | head -1`, it
is better to use `git log -1 --pretty=format:'%T' HEAD`. In general,
`git show <commit-object>` is `git log -1 -p <commit-object>`, and
you do not need diff here.

I may be misunderstanding what the discussion is about as I was not
following the thread, but is this a contest to find the most expensive way
to spell "git rev-parse HEAD^{tree}"?
