-  This file contains the declaration for CppVariant, a type used by C++ classes
-  that are to be bound to JavaScript objects.
-
-  CppVariant exists primarily as an interface between C++ callers and the
-  corresponding NPVariant type.  CppVariant also provides a number of
-  convenience constructors and accessors, so that the NPVariantType values
-  don't need to be exposed, and a destructor to free any memory allocated for
-  string values.
-
-  For a usage example, see cpp_binding_example.{h|cc}.
