-  # MessageVerifier makes it easy to generate and verify messages which are signed
-  # to prevent tampering.
-  # 
-  # This is useful for cases like remember-me tokens and auto-unsubscribe links where the
-  # session store isn't suitable or available.
-  #
-  # Remember Me:
-  #   cookies[:remember_me] = @verifier.generate([@user.id, 2.weeks.from_now])
-  # 
-  # In the authentication filter:
-  #
-  #   id, time = @verifier.verify(cookies[:remember_me])
-  #   if time < Time.now
-  #     self.current_user = User.find(id)
