AdvSys is an object-oriented, LISP-like authoring system for IF, created by David Betz in 1986.
This sub-engine is loosely inspired on the AdvSys interpreter Copyright © 2009 by David Betz. It was released under the BSD license, so I extracted the API & algorithms, and built a fresh version for ScummVM from scratch based on it.
