+[section:concept_checking Concept Checking]
+
+The iterator concept checking classes provide a mechanism for a
+template to report better error messages when a user instantiates the
+template with a type that does not meet the requirements of the
+template. For an introduction to using concept checking classes, see
+the documentation for the boost::concept_check library.
