'''<indexterm><primary>tag</primary></indexterm>'''
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. 

[heading Synopsis]
``template<typename Geometry>
struct tag
{
  // ...
};
``

[heading Template parameter(s)]
[table
[[Parameter] [Description]]
[[typename Geometry] [Any type fulfilling a Geometry Concept]]
]

`#include <boost/geometry.hpp>`


Or

`#include <boost/geometry/core/tag.hpp>`
