  What's there to steal?  

	CONF = {}
	f = loadfile("config.lua","t",CONF)
	f()

  And CONF contains the contents of the configuration file.  In C, this
would be:

	lua_createtable(L,0,0);
	lua_setglobal(L,"CONF");

	rc = luaL_loadfile(L,"config.lua","t");
	if (rc == LUA_OK)
	{
	  lua_getglobal(L,"CONF");
	  lua_setupvalue(L,-2,1);
	  rc = lua_pcall(L,0,0,0);	/* we just loaded our config */
	}
