// The SbLazyPimplPtr<> class is loosely based on the boost::pimpl_ptr<>-
37
// proposal of 2005 by Asger Mangaard.
38
//
39
// It is reimplemented here as separate classes, not with policy-based
40
// templates, because we still try to support compilers that don't support
41
// template templates (e.g. Visual C++ 6).
42
//
43
// See also SbPimplPtr<>, our implementation of the immediate-creation
44
// policy.
