---------------

      Consider this interface for a multiple choice poll component (see
      "Poll.py":examples/Poll.py)::

        from Interface import Base

        class Poll(Base):
            "A multiple choice poll"

            def castVote(self, index):
                "Votes for a choice"

            def getTotalVotes(self):
                "Returns total number of votes cast"

            def getVotesFor(self, index):
                "Returns number of votes cast for a given response"

            def getResponses(self):
                "Returns the sequence of responses"

            def getQuestion(self):
                "Returns the question

         The last comment in the interface is missing a closing quotation mark.

         Is it possible to use a variable to hold the value of the question ? I mean is the use of a method to access
         so simple information mandatory ?

         Interfaces are supposed to only have methods, and no variables.
