-/// \file
-/// This file provides a polymorphic_ptr class template. See the class comments
-/// for details about this API, its intended use cases, etc.
-///
-/// The primary motivation here is to work around the necessity of copy
-/// semantics in C++98. This is typically used where any actual copies are
-/// incidental or unnecessary. As a consequence, it is expected to cease to be
-/// useful and be removed when we can directly rely on move-only types.

-/// \brief An owning, copyable polymorphic smart pointer.
-///
-/// This pointer exists to provide copyable owned smart pointer. Rather than
-/// shared ownership semantics, it has unique ownership semantics and deep copy
-/// semantics. It is copyable by requiring that the underlying type exposes
-/// a method which can produce a (heap allocated) clone.
-///
-/// Note that in almost all scenarios use of this could be avoided if we could
-/// build move-only containers of a std::unique_ptr, but until then this
-/// provides an effective way to place polymorphic objects in a container.
