title: How to include a Module's constants and variables?
body: <p>I have a Module with a constant and variable.</p>
  
  <p>I wonder how I could include these in a class?</p>
  
  <pre><code>module Software
    VAR = 'hejsan'
  
    def exit
      @text = "exited"
      puts @text
    end
  end
  
  class Windows
    extend Software
    def self.start
      exit
      puts VAR
      puts @text
    end
  end
  
  Windows.start
  </code></pre>
  
  <p>Is this possible?</p>
