Marko,

that's quite easy. (from my point of view ;-)))

You have to write your own BoundaryPreparer.
All you have to do is
1. Load your data
2. For each boundary create a Boundary object.
    For a Boundary object you need:
    1. The shape (as java.awt.geom.Area object) with Garmin coordinates
    2. The OSM tags
3. Save each Boundary using the BoundarySaver.addBoundary method.
4. Call BoundarySaver.end()
=> That's it

You receive extra points when you call
BoundaryPreparer.workoutBoundaryRelations(boundsDirectory);
after that :-)
