title: Mercurial batch pull operation
body: <p>I have several repositories for personal use and I back them up on my main server. There are quite a few and it takes quite a bit of time to perform a pull operation on every single repository. </p>
  
  <p>Does mercurial support batch pull of several repositories? If so, how do I go about it? If not, is there a relatively simple solution? </p>
  
  <p>I am using Windows and use TortoiseHg (but I have no problem with using the command line).</p>
