Hi,
Here is a published SNAPSHOT DRAFT of what I have so far for the tutorial.
http://tinkerpop.apache.org/docs/3.1.3-SNAPSHOT/tutorials/gremlin-language-variants/
I've asked Ketrina to do a new graphic for this. It will be CrAzY.
The gremlin-jython.py link is broken as I didn't do a full doc build. Its here
to look at if you are interested:
https://github.com/apache/incubator-tinkerpop/blob/TINKERPOP-1232/docs/static/resources/gremlin-jython.py
