- // The intent is to propose the following for addition to namespace std

- // EXIT_FAILURE. As an implementation detail, this header defines the
- // new constants in terms of EXIT_SUCCESS and EXIT_FAILURE. In a new
- // standard, the constants would be implementation-defined, although it
- // might be worthwhile to "suggest" (which a standard is allowed to do)
- // values of 0 and 1 respectively.
-
- // Rationale for having multiple failure values: some environments may
- // wish to distinguish between different classes of errors.
- // Rationale for choice of values: programs often use values < 100 for
- // their own error reporting. Values > 255 are sometimes reserved for
- // system detected errors. 200/201 were suggested to minimize conflict.

+ * \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
+ * BOOST_CONCEPT_ASSERT((ForwardRangeConcept<T>));
+ * \endcode
+ *
+ * A different concept check is required to ensure writeable value
+ * access. For example to check for a ForwardRange that can be written
+ * to, the following code is required.
+ *
+ * \code
+ * BOOST_CONCEPT_ASSERT((WriteableForwardRangeConcept<T>));
+ * \endcode
+ *
+ * \see http://www.boost.org/libs/range/doc/range.html for details

- //! iterator_range class
- /*!
- An \c iterator_range delimits a range in a sequence by beginning and ending iterators.
- An iterator_range can be passed to an algorithm which requires a sequence as an input.
- For example, the \c toupper() function may be used most frequently on strings,
- but can also be used on iterator_ranges:
-
- \code
- boost::tolower( find( s, "UPPERCASE STRING" ) );
- \endcode
-
- Many algorithms working with sequences take a pair of iterators,
- delimiting a working range, as an arguments. The \c iterator_range class is an
- encapsulation of a range identified by a pair of iterators.
- It provides a collection interface,
- so it is possible to pass an instance to an algorithm requiring a collection as an input.

+ An \c iterator_range delimits a range in a sequence by beginning and ending iterators.

+ boost::tolower( find( s, "UPPERCASE STRING" ) );

+ Many algorithms working with sequences take a pair of iterators,

+ encapsulation of a range identified by a pair of iterators.
+ It provides a collection interface,

-// accuracy of timing information provided by the underlying platform, and
-// this varies a great deal from platform to platform.
