title: Is there a difference between `bzr clone`, `bzr branch` and `bzr checkout`?
body: <p>Obviously <code>bzr clone</code>, <code>bzr branch</code> and <code>bzr checkout</code> all do the same thing when given an URL as parameter and executed in a non-bzr directory.</p>
  
  <p>Is there any difference for later Bazaar workflow? i.e. <code>bzr commit</code>, <code>bzr update</code> and friends.</p>
