FWIW, I've got an initial implementation to add Runewars support to Cryodex. (Tournament software that is often in use for Armada, XWing, Destiny etc)
It's located here : https://github.com/tom-gall/CryodexSource/tree/RunewarsSupport
I've not updated the jar file (no point for the time being) so you'll need to compile it.
That's 'easy' as:
javac cryodex/*.java cryodex/*/*.java cryodex/*/*/*.java
then
java cryodex/Main
Feedback welcome.
