12** If you embed Lua in your program and need to open the standard
13** libraries, call luaL_openlibs in your program. If you need a
14** different set of libraries, copy this file to your project and edit
15** it to suit your needs.
16**
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
