17 ** You can also *preload* libraries, so that a later 'require' can
18 ** open the library, which is already linked to the application.
19 ** For that, do the following code:
20 **
21 ** luaL_getsubtable(L, LUA_REGISTRYINDEX, LUA_PRELOAD_TABLE);
22 ** lua_pushcfunction(L, luaopen_modname);
23 ** lua_setfield(L, -2, modname);
24 ** lua_pop(L, 1); // remove PRELOAD table
