Generates mini mods to automatically build buildings in either your directly held demesne (e.g. county seats), baron vassals in your counties (e.g. county barons) or vassal barons (any direct vassal of yours whose primary title is a barony.) It honors build times, build costs, potentials, prequesitits, and technology requirements. It also benefits from local construction technology bonuses, though not from minister construction bonuses.
Updated on 1/6/15 to fix issue with pagans and prestige. County baron flag still isn't functional, but vassal baron and all vassals works.
ETA on a HIP compatible version?
I uploaded a HIP version shortly after you commented, but just now noticed your comment. In case you are watching for a reply, there is now a HIP version here: Moddb.com
