+-- The Nominatim theme creates a fixed set of import tables for use with

+-- The theme also exports a number of functions that can be used to configure

+-- importing the theme:
+--
+-- local nominatim = themepark:init_theme('nominatim')
+-- nominatim.set_main_tags{boundary = 'always'}
+--
+-- This allows to write your own configuration from scratch. You can also
+-- use it to customize topics. In that case, first add the topic, then
+-- change the configuration:
+--
+-- themepark:add_topic('nominatim/full')
+-- local nominatim = themepark:init_theme('nominatim')
+-- nominatim.ignore_tags{'amenity'}
