// Including this header will cause compilation to fail
// if CGAL_NO_DEPRECATED_CODE is defined. If this is not the case, it will issue
// a warning during compilation, unless CGAL_NO_DEPRECATION_WARNINGS is defined.

// CGAL_DEPRECATED_HEADER, CGAL_REPLACEMENT_HEADER, and
// CGAL_DEPRECATED_MESSAGE_DETAILS can be defined
// to a string literal to customize the warning.

// CGAL_DEPRECATED_HEADER, CGAL_REPLACEMENT_HEADER, and

// The lack of an include guard is intentional and necessary.
