Jeez, what's ey doing?  You can't nest functions like that in standard
C.  GNU C supports some of that as an extension, but still...

Wow, and look at the brash and insulting "no content" message if you
try to access the root of that site to see who the author is.

5.0 doesn't have an exactly compatible interface with 5.1; there is no
liblualib51.  I'd start with the 5.1 reference manual, but that's me.

http://lua-users.org/wiki/SimpleLuaApiExample seems to have something like
that, though I haven't read it enough to vouch for its quality.  Could you
try that and see whether it works for you?
