Library for Converting Data to and from C Structs for Lua 5.1/5.2. This library offers basic facilities to convert Lua values to and from C structs. Its main functions are struct.pack, which packs multiple Lua values into a struct-like string; and struct.unpack, which unpacks multiple Lua values from a given struct-like string.
And this morning i found that u have written such a good tool for converting lua code to C. I think this will help me a lot, atleast it will show me a way, for my interface to lua from C. I think tools like lua2c and jlua will help lua's proliferation.

----- lua 5.1 script to convert a lua file into a C file
----- Usage: lua2c foo.lua > lfoo.c # compiled, so not portable
----- lua2c -s foo.lua > lfoo.c # source, and so portable
