title: How can refer to external sources?
body: <p>I'm using Eclipse Juno with Pydev 2.7.1, but I would like to import an external folder in order to modify its contents directly from Eclipse's editor (and reciprocally) .</p>
  
  <p>Is that really impossible ?</p>
  
  <p>I've looked at <a href="https://stackoverflow.com/questions/7394031/how-do-you-create-a-pydev-project-from-existing-code">this stackoverflow post</a>, but it did say how to add external files to PYTHONPATH.
  I've also found <a href="https://stackoverflow.com/questions/12519327/how-to-define-an-external-source-folder-in-pydevproject">this stackoverflow post</a> : but I still can't edit the external files :(</p>
  
  <p>Thanks in advance.</p>
