title: 'module' object has no attribute 'RawConfigParser' in coverage.py
body: <p>I was able to successful install coverage using -user and try to use api as we have wrapper which was difficult to call  coverage from command line So I call api and write import coverage But I endup with following error.Could you please provide the input.</p>
  
  <p>when I write simple import it works but it failes if I call from wrapper.
  In short, we have one script in which call functional script or main script.</p>
  
  <p>Is it possible to do coverage of inner module also if we invoke other module also</p>
