 # This is the osm2pgsql .style file for openstreetmap-carto.
-# phstore is used instead of polygon,nocolumn to preserve compatibility
-# with older osm2pgsql versions
+# It is inteded to be used with openstreetmap-carto.lua and osm2pgsql Lua
+# transforms. Full usage details are in INSTALL.md
+# Among things, this means that the linear vs polygon distinction in this file
+# doesn't matter, because that is set in the Lua and this file is only used for
+# column names and types.
