    To create a local snapshot from the current installed version:
    whirlwind --snapshot /some/path/
    
    General options:
    --environment # set to a name that is used to organize your fixture data.
                    For example, test, dev, prod
    --browser # set to a valid selenium-webdriver supported browser
    --site # optional, if the test site name is provided run all features
           # for that site.  If this is not provided pass a feature file
           as the last argument
         
    To execute the example demo site test.  This assumes you have started
    the demo site located under demo_test_site.

    cd /local/snapshot/dir
    ./bin/whirlwind --site sites/demo --browser ff --environment test

    Test results are stored under sites/<site_name>/results.
