To inherit, just put the name of tile you want to inherit from in parenthesis
at the beginning of the specification.
E.g.
road-1-1 (road) roads/1-1 (road-north)(road-south)
will define a tile named "road-1-1", which first starts with all the images
and properties of tile "road" and then layers on top of that the 'road/1-1'
image, and then sets the 'road-north' and 'road-south' flags.
