/**
* @class vtkABI
* @brief manage macros for exporting symbols in the binary interface.
*
* This header defines the macros for importing and exporting symbols in shared
* objects (DLLs, etc). All VTK headers should use these macros to define the
* kit specific import/export macros. So for the vtkCommon kit this might be,
*
* \code
* #include "vtkABI.h"
*
* #if defined(VTK_BUILD_SHARED_LIBS)
* # if defined(vtkCommon_EXPORTS)
* # define VTK_COMMON_EXPORT VTK_ABI_EXPORT
* # else
* # define VTK_COMMON_EXPORT VTK_ABI_IMPORT
* # endif
* #else
* # define VTK_COMMON_EXPORT
* #endif
* \endcode
*
* See http://gcc.gnu.org/wiki/Visibility for a discussion of the symbol
* visibility support in GCC. The project must pass extra CFLAGS/CXXFLAGS in
* order to change the default symbol visibility when using GCC.
* Currently hidden is not used, but it can be used to explicitly hide
* symbols from external linkage.
