title: Comprehensive beginner's virtualenvwrapper tutorial?
body: <p>I am very impressed by <a href="https://stackoverflow.com/questions/5844869/comprehensive-beginners-virtualenv-tutorial">Comprehensive beginner&#39;s virtualenv tutorial?</a> question. I started reading it because, finally, I have decided to use virtualenv. </p>
  
  <p>But I have also found about virtualenvwrapper <a href="http://virtualenvwrapper.readthedocs.org/en/latest/" rel="nofollow noreferrer">http://virtualenvwrapper.readthedocs.org/en/latest/</a>, and as I understand it virtualenvwrapper is better.</p>
  
  <p>I did read <a href="http://blog.fruiapps.com/2012/06/An-introductory-tutorial-to-python-virtualenv-and-virtualenvwrapper" rel="nofollow noreferrer">http://blog.fruiapps.com/2012/06/An-introductory-tutorial-to-python-virtualenv-and-virtualenvwrapper</a> and <a href="http://doughellmann.com/2008/05/virtualenvwrapper.html" rel="nofollow noreferrer">http://doughellmann.com/2008/05/virtualenvwrapper.html</a>, but from beginner point I still have questions about virtualenvwrapper:</p>
  
  <ol>
  <li><p>As beginner, who has no experience with virtualenv, should I first start using virtualenv, or to go directly to virtualenvwrapper ?</p></li>
  <li><p>What is the benefit of virtualenvwrapper ? As far as I understand it is useful when you have many virtual environments.</p></li>
  <li><p>If I start project with virtualenv, can I later use virtualenvwrapper on it ? Or I need to convert it to virtualenvwrapper, if so how to do conversion ?</p></li>
  <li><p>What is the benefit of Lazy Loading <a href="http://virtualenvwrapper.readthedocs.org/en/latest/install.html#lazy-loading" rel="nofollow noreferrer">http://virtualenvwrapper.readthedocs.org/en/latest/install.html#lazy-loading</a> ?</p></li>
  </ol>
  
  <p>Thanks, </p>
