This is just an extension sample in the distribution. It's
not really widely used. LuaSocket only officially supports
things that can be done both on Windows and on Unix. 
There is no documentation because I thought it would save me
time. :) At any rate, it is completely analogous to TCP.

    -- send stdin through unix socket
    socket = require"socket"
    socket.unix = require"socket.unix"
    c = assert(socket.unix())
    assert(c:connect("/tmp/foo"))
    while 1 do
        local l = io.read()
        assert(c:send(l .. "\n"))
    end

Do you need more help?

Regards,
Diego
