LuaCOM has some policies concerning parameter passing. They
specify how LuaCOM will translate COM parameter lists to Lua
and vice-versa. There are two different situations to which these
policies apply: calling a method of a COM object from Lua and
calling a Lua function from COM. The main question here is how to
deal with the different types of parameters supported by COM
(``in'' parameters, ``out'' parameters, ``in-out'' parameters,
``optional'' parameters and ``defaultvalue'' parameters). There is
also a special policy concerning generic LuaCOM objects.
