Ruby to convert to STL

STL_ASCII  = 'ASCII'.freeze
OPTIONS = {
  'selection_only' => false,
  'export_units'   => 'Model Units',
  'stl_format'     => STL_ASCII
}

STL_Exporter = CommunityExtensions::STL::Exporter

model_basename = File.basename(model_path, ".skp")
model_dir = File.dirname(model_path)

Dir.entries(model_dir).each{ |d|
	file_load = File.join(model_dir,d)
	next if File.extname(file_load).upcase!=".SKP"

    model = Sketchup.active_model
    entities = model.active_entities
    definitions = model.definitions
    status = entities.clear!    
    componentdefinition = definitions.load( file_load )
    
    point = Geom::Point3d.new 0,0,0
    transform = Geom::Transformation.new point
    instance = entities.add_instance componentdefinition, transform
    
	e = instance
	target_size = 1.m
	s = [e.bounds.width, e.bounds.height, e.bounds.depth].max
	r = target_size / s
	t = Geom::Transformation.scaling(r)
	e.transform!(t)

	mpath = Sketchup.active_model.path

	outfile = "#{model_dir}/#{mbasename}.stl"

	STL_Exporter.export(outfile, OPTIONS)
}

Will be nice to have more description please for those who are not familiar with Python.
