- Metafunction defining [*type] as the tag of the specified geometry type.
- [heading Description]
- With Boost.Geometry, tags are the driving force of the tag dispatching mechanism. The tag metafunction is therefore used in every free function.

- ``template<typename Geometry>
- struct tag
- {
- // ...
- };
- ``
