title: Is there a way to pass command line arguments to spec/rspec?
body: <p>Trying to pass some arguments to <code>rspec</code>, but coulnd't find any proper command-line options for the purpose. I <em>could</em> use environment variable for that, but not sure it is the best (and most transparent) way to configure the tests.</p>
  
  <p>So, how can I pass the command-line arguments? If can't - which is the best and most acceptable alternative?</p>
