No, thanks :-) This is not my code.
I just thought that such a basic module is already implemented
and widely accepted by LUA community.

It trivial to implement getopt_long in LUA. I did it for AWK some time
ago, ~150 lines of code. Also the problem with C code is that
getopt_long(3) is not available on Solaris/HP-UX and some
others. getopt_long(3) is not portable.
