title: Is it possible to have a Thor method that is not an explicit task
body: <p>I have a Thor script that uses several methods</p>
  
  <pre>
  class Update &lt; Thor
     desc "do_it", "a simple task"
     def do_it
       puts i_did_it
     end
  
     # no desc here !!!
     def i_did_it
       "I did it"
     end 
  end
  </pre>
  
  <p>Is this possible? Without an explicit task, the tasks list can't be built correctly.</p>
  
  <p>Thanks,</p>
  
  <p>Tim </p>
