13** If you embed Lua in your program and need to open the standard
14** libraries, call luaL_openlibs in your program. If you need a
15** different set of libraries, copy this file to your project and edit
16** it to suit your needs.
17**
18** You can also *preload* libraries, so that a later 'require' can
19** open the library, which is already linked to the application.
20** For that, do the following code:
21**
22**  luaL_getsubtable(L, LUA_REGISTRYINDEX, LUA_PRELOAD_TABLE);
23**  lua_pushcfunction(L, luaopen_modname);
24**  lua_setfield(L, -2, modname);
25**  lua_pop(L, 1);  // remove PRELOAD table
