IIRC, back in the 5.0 days the auxiliary library (functions starting
with luaL) wasn't documented.
You can see the luaL_openlib source here:
http://www.lua.org/source/5.0/lauxlib.c.html#luaL_openlib

It's the same as luaL_register in 5.1, but with an extra 'nup'
parameter that allows adding upvalues.
http://www.lua.org/manual/5.1/manual.html#luaL_register

The 'nup'  parameter works the same as Lua 5.2's luaL_setfuncs;
(luaL_setfuncs is just like luaL_register without the 'libname' parameter.)
