luabind::module(L)[
luabind::class_<StartConfig>("StartConfig")
.def("c_Load", &StartConfig::Load)
.def("c_Unload", &StartConfig::Unload)
.def("c_Register", &StartConfig::Register),
luabind::def("c_GetStartConfig", &StartConfig::GetInstance, luabind::adopt(luabind::result))
];
执行之后，挂在luabind\detail\class_registry.hpp里的
int cpp_class() const { return m_cpp_class_metatable; }

没用过，帮不上。
