Copying repositories

Unlike CVS, for example, there is no separate notion of
"repository" and "working tree". A git repository normally *is* the
working tree, with the local git information hidden in the `.git`
file, which had no differences in the `mybranch` branch), and say:

- Nope.

Not to worry. It left the (trivial) conflict in `hello` in the same form you
should already be well used to if you've ever used CVS, so let's just
Now, let's pretend you are the one who did all the work in
`mybranch`, and the fruit of your hard work has finally been merged
to the `master` branch. Let's go back to `mybranch`, and run

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
