anchor.diff:  If the `Cluster` instance is supplied externally, as is shown above, then it is not closed implicitly by the close of
   the `RemoteGraph`.  In this case, the `Cluster` must be closed explicitly.
   
  -WARNING: `RemoteGraph` does not support steps that use lambdas in the `Traversal`. Lambda expressions are not
  -serializable and therefore can't be remotely executed.
  +IMPORTANT: `RemoteGraph` uses the `TraversalOpProcessor` in Gremlin Server which requires a cache to enable the
  +retrieval of side-effects (if the `Traversal` produces any). That cache can be configured (e.g. controlling eviction
  +times and sizing) can be done in the Gremlin Server configuration file as described <<traversalopprocessor, here>>.
   
   Configuring
   ~~~~~~~~~~~
  
positive.code: other setting, `gremlin.remoteGraph.driver.clusterFile`, is a configuration to `DriverRemoteConnection`, and it
  provides a pointer to the config file to use to construct a `gremlin-driver` `Cluster` object to be utilized when
  connecting to Gremlin Server. Please see the <<connecting-via-java, "Connecting Via Java">> section for more
  information on those classes and their usage. Finally, the `gremlin.remoteGraph.driver.graphName` setting tells the
  `DriverRemoteConnection` the name of the graph in Gremlin Server to connect to.
  
  Gremlin Server needs to be running for this example to work. Use the following configuration:
  
  
negative.code: `TinkerGraph` or `Neo4jGraph`, in that most of its methods are not implemented. For example, calls to most methods
  like, `addVertex()` or `edges()` will result in an `UnsupportedOperationException`. The only method used on
  `RemoteGraph` is `traversal()`, which generates a `GraphTraversalSource` that includes a `RemoteStrategy`. The
  `RemoteStrategy` takes traversals constructed from it, serializes them and submits them to Gremlin Server
  and the results are returned as though working with the `Graph` instance in embedded mode.
  
  `RemoteGraph` is an interesting alternative to the other methods for connecting to Gremlin Server in that all other
