In the good old days you could open "." and read its contents, but this now
gives an error (at least in Linux). :-(

% cat .
cat: .: Is a directory

There *is* a posix library for Lua 5.0 at
	http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/

But perhaps it is easy to write a small portable library for directory
processing. It can't be hard to write a readdir emulation for other platforms.
It's probably already available somewhere in the web and so it'll be simply a
matter of wrapping it for Lua (using the relevant POSIX binding).

If someone knows of a multiplatform readdir emulation, please let me know.
