[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.
