You can expose values to lua using the API wrappers in luabind. For
instance:

  luabind::globals(L)["something"] = some_value;

Is that what you are looking for?

It's also possible to export public members using def_readwrite() and
def_readonly():

  class_<X>("X")
      .def_readwrite("value", &X::value)

You can not however export non-member variables as properties.
