To have access to these libraries, the C host program should call the
luaL_openlibs function, which opens all standard libraries.
Alternatively, the host program can open them individually by using
luaL_requiref to call luaopen_base (for the basic library),
luaopen_package (for the package library), luaopen_coroutine (for the
coroutine library), luaopen_string (for the string library),
luaopen_table (for the table library), luaopen_math (for the
mathematical library), luaopen_bit32 (for the bit library), luaopen_io
(for the I/O library), luaopen_os (for the Operating System library),
and luaopen_debug (for the debug library). These functions are
declared in lualib.h.
