title: virtualenvwrapper: where is virtualenv info stored?
body: <p>I regularly use <code>setvirtualenvproject /path/to/my/project/</code> to set the root/base directory of my virtual env. This is useful when switching to a virtual env using <code>workon myenv</code>.</p>
  
  <p>I was wondering though, if this path is available anywhere else?</p>
  
  <p>In my case, I want to run a pre-push hook in git, and need to get the full path to some of my files.
  e.g. something like this in my pre-push hook:
  <code>do_something $VIRTUALENV_PROJECT/my/important/file.txt</code></p>
  
  <p>Is there any way I can retrieve this 'virtualenvproject' info, or where is it stored?</p>
  
  <p>I've tried looking in <code>env</code>, the <code>.virtualenvs</code> dir and every other place I can think of, but I just can't find where the info's stored.</p>
