As far as I understand it, only a system-depende module for loading ddls
or shared objects is needed. My bare-bones loadlib does this for Unix and
Windows.

The protocol is simply that you know the name of a function in the ddl/so
that you have to call to do whatever is needed by your library, typically
register modules and functions in Lua.

As far as I know, simply having lualib as a dll/so and creating your module
with it is sufficient. There's a Unix example that does this in my
bare-bones loadlib tarball. I don't know how this would work in Windows,
but I recall that someone in the list tested my Windows module and it worked.
