Deep Learning Extension Source Code?

Hello,

I am looking for the source code of the Deep Learning Extension. In particular I am intereseted of how to bundle the different platform dependent jars into the extention jar and the load it dynamically.

Since the Extension is labeled as AGPL Licence I suspect the code should be available. Unfortunately I could only find a very old repo from rapidminerchina here: https://github.com/LostSummer233/rapidminer-extension-dl4j-pack

Where can I find the source of the current version? Any help to solve the mystery of loading the nd4j stuff dynamically in RapidMiner would be appreciated!

Thanks!
