[mkgmap-dev] Question to --add-pois-to-areas

Hi! How should --add-pois-to-areas work? Here is a Zoo:http://www.openstreetmap.org/?lat=28.40885&lon=-16.56398&zoom=17&layers=B000... but it has got neighter icon nor can it be found in the POI search. How is this option expected to work? TIA, Dani P.S: This part is very small so maps are generated very fast: http://download.geofabrik.de/osm/africa/canary_islands.osm.bz2
