title: How do you get cucumber/guard to filter on tags like @wip?
body: <p>I'm running spork and guard and all has been going very well with my RSpec tests which were all run correctly. In order to speed up the tests I could successfully filter my RSpec tests with tags I placed in my <code>.rspec</code> file.</p>
  
  <p><strong>.rspec</strong></p>
  
  <pre><code>--colour
  --debug
  --tag focus
  --tag now
  </code></pre>
  
  <p>Unfortunately though I have not been able to filter my cucumber tags. Every time cucumber runs it runs either <em>everything</em> or just the file that changed. </p>
  
  <p>How can I get cucumber/spork/guard to respect tags like @wip, @now etc and run only those tests? Is there some equivalent to the <code>.rspec</code> file for cucumber tags?</p>
