请问这句声明tlb的代码是什么意思？多谢

#import "E:\现在的工作\TypeLib\VirtualWorldCore.tlb" raw_interfaces_only, raw_native_types, no_namespace, named_guids, exclude("IAsyncManager","ISpatialReference", "IGeometry", "IPoint", "IPolygon", "IPolyline","geoGEOMETRYTYPE","IRing","IPath","IPoint","geoUnits","IClone","IGeoGridDBLayer","tagGrid_MAPTYPE","geoEllipsoidStyle","geoEllipsoidStyle","IGeoGridDBPyramid","geoProjectionStyle","tagGrid_COMPRESSFLAG","IGeoGridDB","IID_IGeoGridDB","IGeometryCollection","IID_IGeoGridDB","IID_IGeometry","IEnvelope")对不起，比较长，我主要是想知道raw_interfaces_only，raw_native_types，no_namespace，named_guids，exclude（"接口名..."）是什么意思，望高人指教
