@realman543 Vassal has a (optional?) gui for it built into the client; instead of opening a module, right-click -> edit.
Vassal is written in java, you can tell by the pixels (window styling), but modules are xml.

I categorised almost everything, there's a misc folder with ~30 items. Categories may not be 100% correct, but I did go through them all to dedupe so I'm pretty confident.
Also Nature Incarnate removes/replaces a bunch of cards, mainly events. I'll post all the rulebooks in a few hours so you can check it.
