[/Templates]
[template concept[name type]
The [name] Concept describes the requirements for a [type] type.
All algorithms in Boost.Geometry will check any geometry arguments against the concept requirements.
]

[template heading_conformance_no_ogc[function]
[heading Conformance]
The function [function] is not defined by OGC.
]

[template heading_conformance_ogc[function ogc_function]
[heading Conformance]
The function [function] implements function [ogc_function] from the __ogc_sf__.
]

[template conformance_std[function std_function]
The function [function] conforms to the [std_function] of the C++ std-library.

[template see_boost_range_sample[concept]
[note See also the sample in the [@../../../range/doc/html/range/reference/extending/method_2.html Boost.Range documentation]
