Detailed Description

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.
