`git-commit-tree` normally takes several arguments -- it wants to know
what the 'parent' of a commit was, but since this is the first commit
ever in this new repository, and it has no parents, we only need to pass in

And this is where we create the `.git/refs/heads/master` file

Unlike CVS, for example, there is no separate notion of
"repository" and "working tree". A git repository normally *is* the

Although git is a truly distributed system, it is often
convenient to organize your project with an informal hierarchy

It should be stressed that this hierarchy is purely *informal*.
There is nothing fundamental in git that enforces the "chain of
