Code Releases Activity

Add "Blender for Korman" and build/package process.

Browse Source 
This will allow us to automate releases with the Blender 2.79
"experimenntal nightly" codebase. This is great because the newer
Blender uses Python 3.7 (instead of 3.5). This pulls from my fork of
Blender, which has a number of build improvements added on top.
