docs: A plugin for helga to automatically remember important things. Unless specified
      by the setting ``FACTS_REQUIRE_NICKNAME``, facts are automatically stored when
      a user says: ``something is something else``. Otherwise, facts must be explicitly
      added: ``helga something is something else``.
  
      Response format is, by default, the full message that was sent, including an author
      and timestamp. However, if a user specifies the string '<reply>' in their message,
      then only the words that follow '<reply>' will be returned in the response.
  
      For example::
  
          <sduncan> foo is bar
          <sduncan> foo?
          <helga> foo is bar (sduncan on 12/02/2013)
  
      Or::
  
          <sduncan> foo is <reply> bar
          <sduncan> foo?
          <helga> bar (sduncan on 12/02/2013)
  
      To remove a fact, you must ask specifically using the ``forget`` command::
  
          <sduncan> helga forget foo
          <helga> forgotten
  
      To replace a fact, you must use the ``replace`` command, andprovide the
      term as well as the new definition, separated by  '<watch>'::
  
          <sduncan> helga replace foo <with> new def
          <helga> replaced
