-** If you embed Lua in your program and need to open the standard
-** libraries, call luaL_openlibs in your program. If you need a
-** different set of libraries, copy this file to your project and edit
-** it to suit your needs.
-**
-** You can also *preload* libraries, so that a later 'require' can
-** open the library, which is already linked to the application.
-** For that, do the following code:
-**
-**  luaL_getsubtable(L, LUA_REGISTRYINDEX, LUA_PRELOAD_TABLE);
-**  lua_pushcfunction(L, luaopen_modname);
-**  lua_setfield(L, -2, modname);
-**  lua_pop(L, 1);  // remove PRELOAD table
