  The layer should be a pre-existing OSM layer in the database created with OSM import.
  The layerspec(s) are strings that are composed of multiple '-' or '.' separators.
  Each pair in order is treated as a property-value pair to match when searching the
  original layer for the new dynamic layer geometries.

For example:
  ./osm_layer.rb -D db croatia.osm highway highway-residential natural-water

This will define three dynamic layers in the croation.osm dataset:
  highway               all ways that have a 'highway' property
  highway-residential   all ways that have 'highway'='residential'
  natural-waterway      all ways that have 'natural'='waterway'
