// For Microsoft Visual C++, externally accessible symbols must be

//
// The following ifdef block is the standard way of creating macros
// which make exporting from a DLL simpler. All files within this DLL
// are compiled with the DLL_EXPORTS preprocessor symbol defined on the
// command line. In contrast, projects that use (or import) the DLL
// objects do not define the DLL_EXPORTS symbol. This way any other
// project whose source files include this file see DLL_API functions as
// being imported from a DLL, whereas this DLL sees symbols defined with
// this macro as being exported.
