print("Air has the content id: " .. tostring(c_air))

local manip = minetest.get_voxel_manip()
local emin, emax = manip:read_from_map(minp, maxp)
local area = VoxelArea:new({MinEdge=emin, MaxEdge=emax})
local data = manip:get_data()
for z = minp.z, maxp.z do
   for y = minp.y, maxp.y do
      local vi = data:index(minp.x, y, z)
      for x = minp.x, maxp.x do
         --remove all nodes in the area - set to air
         data[vi] = c_air
         vi = vi + 1
      end
   end
end
