luaopen_* pushes table to the stack?

[Tim Conkling <tconkling@...>]

After calling luaopen_base (with an empty lua stack), my Lua stack contains
one item (a table) with functions keyed to the strings "resume", "yield",
"status", "wrap", and "create". I couldn't find anything in the docs for the
luaopen_* functions that says that anything should be pushed to the stack
after calling one of them. What is this table and why is it there?

Thanks,
Tim
