If you have built your Lua appropriately, and on a platform that can
support it, you can use io.popen:

	http://www.lua.org/manual/5.1/manual.html#pdf-io.popen

If not, and you don't want to have to resort to C, you'll have to get
your system's shell to redirect the output to a file, and then read it
in.
