/*
** 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, "_PRELOAD");
**  lua_pushcfunction(L, luaopen_modname);
**  lua_setfield(L, -2, modname);
**  lua_pop(L, 1);  // remove _PRELOAD table
