It's build from CyanogenMod Sources with some Samsung libraries that are necessary for hardware.
Rewriting all Samsung Stuff would take years.
But it's completely free of Touchwiz.
Built from Source:
Core Libraries
Android Framework
Dalvik
Mediaserver
and much more i couldn't remind.
Dalvik doesn't create dex files for some Google Apps at the moment. And then these Apps are crashing due to missing classes which should be at these missing dex files.
I don't know why.
There's so much to do.
