+**NOTE:** This sample was written with a Java backend in mind. As a result, 
+the generated code will differ slightly than that for the [Python Tic Tac
+Toe sample][8]. For the most part this will be immaterial to the sample,
+but there are a few key differences:
+- The generated schema names in the discovery document are different in Python
+  than in Java, even though the hold the same data. This will cause the generated
+  classes corresponding to the schema to have different names.
+- Python supports enums and uses `'WHEN'` and `'TEXT'` for the `order` field in
+  queries, while Java simply uses `"0"` and `"1"`, respectively.
+- The Python backend stores the current user for authenticated requests, but does
+  not return the user in the score insert response or score list response.
