Thanks, but it doesn't particularly need to be within
Lua, and we'd MUCH rather not change Lua if we don't
have to. We have a facade program that needs this
functionality from Ruby, presumably via a C library.
The current code is almost exactly what we need except
that it uses file and printf I/O rather than C strings
(char* buffers).
