How to make certain buildings available to factions they dont "belong" to?

[Socy]

Heya all.

After "mastering" the art of adding new units, applying skins (already existing) etc. to them I've run into a new problem when "modding". Namely, I'd very much like to enable the Sweboz of creating those awesome Celtic large walls (Equialent of Stone Walls). Now, how exactly would I do this? Anyone can give me a pointer in the right direction?

Well, I know its a lot easier than adding units...

I don't have the files with me now, but I think the file is eb\data\export_desc_building.txt, (back it up first of course)
after each building there should be a list of factions that can build it
find stone_walls and add "germans" to the line, while you're in there, find the large bath house building and add germans to it too. I don't know what the walls will look like though but the last time I checked the Sweboz had their own faction specific description for bathhouses.

cheers!
