Packing Manager

Allows you to programmatically setup your exported unitypackage in a predictable manner. 

You specify the actions you want to take in a PackingInstructions.json file. This allows you to nest unitypackages into each other if you wish. You can go as simple or as complicated as you wish. The instructions are taken in order. 

This is great for anyone looking to share their work or sell on a store page. It allows you to build exactly what you want without making any mistakes.
