#define IMP_COPY_CONSTRUCTOR	(		Name,
			Base
	)

Use a copy_from method to create a copy constructor and operator=.

This macro is there to aid with classes which require a custom copy constructor. It simply forwards operator= and the copy constructor to a method copy_from() which should do the copying.

You should think very hard before implementing a class which requires a custom copy constructor as it is easy to get wrong and you can easily wrap most resources with RAII objects (Wikipedia entry).

#define IMP_UNIQUE_PTR

Smart pointer to retain sole ownership of an object through a pointer.

In C++11 mode, this is std::unique_ptr; otherwise, it is std::auto_ptr. Note that these two classes do not have exactly the same interfaces, so you must be careful to use IMP_UNIQUE_PTR only in cases where the two classes behave in the same way (e.g. you cannot copy a unique_ptr, but you can copy an auto_ptr; unique_ptr works with arrays and can be stored in STL containers, unlike auto_ptr).
