title: Is it possible to setup environment variables within noses setup.cfg
body: <p>I'm working with a fairly sprawling embedded python project. At the moment the tests is hidden behind a make invocation which sets up PYTHONPATH and LD_LIBRARY_PATH on the workstation so the tests can complete. Is it possible to specify this within the nose configuration so that the user need only invoke <em>nosetests</em> in the directory?</p>
  
  <p>Otherwise should I just include some boiler-plate in the test files to manipulate the required paths?</p>
