Ecosystem is a cross-platform environment management system from Peregrine Labs originally developed for VFX/Animation production R&D but could be used in any situation where a fine understanding of your working environment is important (and it really should be!).
Please refer to the https://github.com/PeregrineLabs/Ecosystem for more details.
This repository contains all of the .env files as required by Ecosystem and may be forked/updated as you see fit.
