+ * \file
+ * \brief Concept checks for the Boost Range library.
+ *
+ * The structures in this file may be used in conjunction with the
+ * Boost Concept Check library to insure that the type of a function
+ * parameter is compatible with a range concept. If not, a meaningful
+ * compile time error is generated. Checks are provided for the range
+ * concepts related to iterator traversal categories. For example, the
+ * following line checks that the type T models the ForwardRange
+ * concept.
+ *
+ * \code
+ * function_requires<ForwardRangeConcept<T> >();
+ * \endcode
+ *
+ * An additional concept check is required for the value access
+ * property of the range. For example to check for a
+ * ForwardReadableRange, the following code is required.
+ *
+ * \code
+ * function_requires<ForwardRangeConcept<T> >();
+ * function_requires<
+ *     ReadableIteratorConcept<
+ *         typename range_iterator<T>::type
+ *     >
+ * >();
+ * \endcode
+ *
+ * \see http://www.boost.org/libs/range/doc/range.html for details
+ * about range concepts.
+ * \see http://www.boost.org/libs/iterator/doc/iterator_concepts.html
+ * for details about iterator concepts.
+ * \see http://www.boost.org/libs/concept_check/concept_check.htm for
+ * details about concept checks.
