Marko A. Rodriguez commented on TINKERPOP-1232:
-----------------------------------------------

We should look at http://gremlinclient.readthedocs.org/en/latest/ for 
inspiration on Python talking to Gremlin Server over the binary protocol.

> Write a tutorial demonstrating the 3 ways to write a Gremlin language variant.

> Talking with [~rustyrazorblade] about collaborating on a Gremlin tutorial for 
> language designers. Here is what we came up with.
> We will use Python as the host language and demonstrate 3 ways to create 
> Gremlin-Python.
> * Using Jython: With Jython you have direct access to the JVM and thus can 
> call {{GraphTraversal}} methods directly. We can expose some Python sugar 
> here and there to show why its good to have a language specific variant. See 
> Gremlin-Scala for inspiration.
> * Using JNI: With Python, we have a {{PythonTraversal}} Python class. That 
> class then uses Java Gateway to interact (via proxy) with {{GraphTraversal}}. 
> This was done in the past as an experiment with R using rJava.
> * Using String: With Python, we have a {{PythonTraversal}} Python class where 
> {{out("knows")}} simply appends {{"out(\"knows\")"}} to a string builder. The 
> result can then be a String sent to a {{RemoteConnection}} for evaluation.
> These three models are the three ways in which any language can embed 
> Gremlin.
