+## Description
+
+The `make_unique` function templates provide convenient and safe ways to
+create `std::unique_ptr` objects.
+
+## Rationale
+
+The C$$++$$11 standard introduced `std::unique_ptr` but did not provide any
+`make_unique` utility like `std::make_shared` that provided the same
+exception safety and facility to avoid writing `new` expressions. Before it
+was implemented by some standard library vendors (and prior to the C$$++$$14
+standard introducing `std::make_unique`), this library provided it due to
+requests from users.
+
+This library also provides additional overloads of `make_unique` for
+default-initialization, when users do not need or want to incur the expense
+of value-initialization. The C$$++$$ standard does not yet provide this
+feature with `std::make_unique`.
+
+## Synopsis
+
+`make_unique` is defined in `<boost/smart_ptr/make_unqiue.hpp>`.
+
+[subs=+quotes]
+```
+namespace boost {
+  template<class T, class... Args>
+    std::unique_ptr<T> make_unique(Args&&... args);
+
+  template<class T>
+    std::unique_ptr<T> make_unique(_see below_ v);
+
+  template<class T>
+    std::unique_ptr<T> make_shared(std::size_t n);
+
+  template<class T>
+    std::unique_ptr<T> make_shared_noinit();
+
+  template<class T>
+    std::unique_ptr<T> make_shared_noinit(std::size_t n);
+}
+```
+
+## Free Functions
+
+```
+template<class T, class... Args>
+  std::unique_ptr<T> make_unique(Args&&... args);
+```
+::
+Remarks::: These overloads shall only participate in overload resolution when
+`T` is not an array type.
+Returns::: `std::unique_ptr<T>(new T(std::forward<Args>(args)$$...$$)`.
+Example::: `auto p = make_unique<int>();`
+
+[subs=+quotes]
+```
+template<class T>
+  std::unique_ptr<T> make_unique(_see below_ v);
+```
+::
+Remarks:::
+* These overloads shall only participate in overload resolution when `T` is
+not an array type.
+* The type of `v` is `std::remove_reference_t<T>&&`.
+Returns::: `std::unique_ptr<T>(new T(std::move(v))`.
+Example::: `auto p = make_unique<std::vector<int> >({1, 2});`
+
+```
+template<class T>
+  std::unique_ptr<T> make_unique(std::size_t n);
+```
+::
+Remarks::: These overloads shall only participate in overload resolution when
+`T` is an array type of the form `__U__[]`.
+Returns::: `std::unique_ptr<__U__[]>(new __U__[n]())`.
+Example::: `auto p = make_unique<double[]>(1024);`
+
+```
+template<class T>
+  std::unique_ptr<T> make_unique_noinit();
+```
+::
+Remarks::: These overloads shall only participate in overload resolution when
