[mkgmap-dev] using short_name tag of a boundary

Hi! I have a question which I hope is trivial but I couldn't find answer to: I use default rules to generate name index for my map: mkgmap:city!=* & mkgmap:admin_level8=* { set mkgmap:city='${mkgmap:admin_level8 }' } I want to use names from "short_name" tag instead of "name" tag assigned to boundary=administrative polygon. How is it possible? best regards Michal Rogala
