Currently I'm just getting XML documentation up for the provisional release, basically just all the features that fit really nicely into the original purpose of GAE, which I forked. Layered upgrades, a better experience based level system, and other stuff like that. The more exploratory strategy, as opposed to RTSish, features are left out of the documentation and not as stable.
I'm also working on a demonstration faction with all the stuff working on various units while still being semi playable gameplay wise. This probably won't be interesting to anyone not used to Glest/MG/GAE.
