It seems that the latest documentation is this one:
<https://github.com/GoogleCloudPlatform/appengine-mapreduce/wiki/1-MapReduce>
so I assumed that the code in this repo is the latest, is that so?

It seems that in the SDK one can also find a mapreduce lib under google.appengine.ext.mapreduce.

The issue is that I can't find a working example using either one of them, nor a good installation instructions (just putting the mapreduce dir from the above repo doesn't seem to work). Also running the tests fails.

So before digging in and working through the issues to get it working I wonder if I'm missing something obvious? 

Any help will be great.
