// Every class defined in this file has an _exported next to the class name.
// This is needed for WinTel machines so that the class methods can
// be exported or imported in a DLL as appropriate. Users of the DLL
// use the define DB_USE_DLL. When the DLL is built, DB_CREATE_DLL
// must be defined.
