+This is a variation on the topic of \helpref{wxScopedPtr}{wxscopedptr}. This
+class is also a smart pointer but in addition it ``ties'' the pointer value to
+another variable. In other words, during the life time of this class the value
+of that variable is set to be the same as the value of the pointer itself and
+it is reset to its old value when the object is destroyed. This class is
+especially useful when converting the existing code (which may already store
+the pointers value in some variable) to the smart pointers.
