+
+[section Overview]
+
+The header <boost/core/nvp.hpp> provides the class template `boost::nvp` that
+pairs a name (`const char*`) with the address of a value (`T*`). It is the new
+implementation of the NVP type previously provided by the Boost Serialization
+library. This type now lives in the Core library so that other Boost libraries
+can support named value serialization without taking a dependency on the
+Serialization library.
+
+[endsect]
+
+[section Examples]
+
+The following snippet shows use in a member serialize function:
+
+```
+template<class A>
+void serialize(A& archive, unsigned)
+{
+    archive & boost::make_nvp("x", x_) & boost::make_nvp("y", y_);
+}
+```
+
+[endsect]
+
+[section Reference]
+
+```
+namespace boost {
+
+template<class T>
+class nvp {
+public:
+    nvp(const char* name, T& value) noexcept;
+
+    const char* name() const noexcept;
+
+    T& value() const noexcept;
+
+    const T& const_value() const noexcept;
+};
+
+template<class T>
+const nvp<T> make_nvp(const char* name, T& value) noexcept;
+
+} /* boost */
+
+#define BOOST_NVP(object) ``['see below]``
