You need to export the initialization function. Assuming that you want 
to do require("h9k") then the function you export is luaopen_h9k with 
the same argument and return as any other Lua CFunction.

In the library unit put an exports block. That would look something like:

    library h9k;
    uses {...};
    exports
      luaopen_h9k;
    begin
      { Nothing to do here. }
    end.

The luaopen_h9k function creates a table with the module contents and 
returns it on the stack.

Disclaimer: My Delphi-fu isn't all that great and I've never actually 
created a Lua module with it before.
