Personally, if you only have 20 functions, I'd recommend just writing 
the wrappers by hand.  That way, you don't depend on any outside code.  
The lua documentation is pretty good, and you can look at the lua 
standard library for examples.

Look at lmathlib.c for some very straightforward examples, liolib.c for 
something a little bit more complicated.  It's fairly easy to modify 
the luamain program to use new libraries.

That's a bzip2 file.  I don't know enough about windows compression 
utilities to know which will work; I generally have good luck with 
StuffIt.
