title: Mercurial branching and bookmarks
body: <p>I read some information about named branches and working with bookmarks. Unfortunately I still don't see a difference between them. Is there any?</p>
  
  <p>Is there any difference between:</p>
  
  <pre><code>hg branch blah
  hg up blah
  </code></pre>
  
  <p>and</p>
  
  <pre><code>hg bookmark blah
  hg up blah
  </code></pre>
  
  <p>?</p>
  
  <p>Why would I use a bookmark and how is it different from a named branch?</p>
