// MachDevice.cpp : Defines the initialization routines for the DLL.
//
// Revision history
// 9 June John Prentice - this version separates the user supplied code into another file or files with functions
// called as externals.
// It should be safe to replace the source of the SDK framework
// as upgrades are made with no more user effort than providing dummy entries for
// any new unused functionality and recompiling the plugin.
// The linker will advise of this need so it should be quite crash-resistant
