title: Nosetest: Does it set the errorlevel to 1 on failure?
body: <p>Windows environment, python 2.7, latest nosetest.</p>
  
  <p>Looking at nosetest docs, and googling around, nowhere do I see that nosetest sets the cmd line errorlevel on test failure.</p>
  
  <p>We need this so that our build system can detect test failure.</p>
  
  <p>Questions are:</p>
  
  <ul>
  <li>Does Nosetest set the cmd line, errorlevel?  (if so, where are docs)</li>
  <li>If not, what is the appropriate way to handle this? (must my build parse some log output, or?)</li>
  </ul>
