anchor.diff:     ;; Start talking to remote nodes:
      (spawn 'node)
      #
  +
  +   *Side Effects:*
  +
  +   {node} changes the host name of the local node to _host_, which is
  +   subsequently used as a default argument to {spawn}.
   
      *Exceptional Situations:*
   
  
positive.code: 
     If _node_ is _non-nil_ the _agent_ is started on _node_ of _host_ instead of
     the local node.
  
     *Exceptional Situations:*
  
  
negative.code:    _node_—a _node name_ or {nil}. The default is {nil}.
  
     _host_—a _host_ as accepted by [resolve-address](http://ccl.clozure.com/docs/ccl.html#f_resolve-address).
     The default is the host name of the local node.
