Empty directories where branches are, and how to work centrally (was Re: questions from a new bzr user)

Dear Robert,

Thanks a lot for your detailed and prompt answers. They certainly
solve both of my questions.

Ooops, now I realize that the answer to the first question is implicit
in the checkout tutorial (which I thought I had read  ---I guess its
getting too late here). Would it be worth to include this as an entry
in the bzr web page?

Thanks again for your answers.
