This is the part where I just get lost. In fact, I've tried some
examples with smoke using C++ and everything is nice. So if my
language could interface with C++ I would be in heaven but that's not
the case, so I'm still lost. Let me see if I understand. You have to
create between your language and Smoke a C layer, this C layer is C++
with extern C. Something along the lines:

extern "C" int myFunction {

// C++ code which calls Smoke

}


and then in your language, you just call int myFunction which is C
(name-mangling-wise). Is this OK?
