-This directory contains code that is more useful than the
-samples. This code *is* supported.
-
-    tftp.lua                -- Trivial FTP client
-
-This module implements file retrieval by the TFTP protocol.
-Its main use was to test the UDP code, but since someone
-found it usefull, I turned it into a module that is almost
-official (no uploads, yet).
-
-    dict.lua                -- Dict client
-
-The dict.lua  module started with  a cool  simple client
-for the  DICT protocol, written by Luiz Henrique Figueiredo.
-This new version has been converted into a library, similar
-to the HTTP  and FTP libraries, that can be used from within
-any luasocket application. Take  a look on the  source code
-and you will be able to figure out how to use it.
-
-    lp.lua                  -- LPD client library
-
-The lp.lua module implements the client part of the Line
-Printer Daemon protocol, used to print files on Unix
-machines. It is courtesy of David Burgess!  See the source
-code and the lpr.lua in the examples directory.
-
-    b64.lua
-    qp.lua
-    eol.lua
-
-These are tiny programs that perform Base64,
-Quoted-Printable and end-of-line marker conversions.
-
-    get.lua                 -- file retriever
-
-This little  program is  a client  that uses  the FTP  and
-HTTP  code to implement a  command line  file graber. Just
-run 
-
-        lua get.lua <remote-file> [<local-file>]
-
-to download  a remote file (either  ftp:// or http://) to
-the specified local file.  The program  also prints  the
-download  throughput, elapsed time, bytes already downloaded
-etc during download.
-
-    check-memory.lua        -- checks memory consumption
-
-This is just to see how much memory each module uses.
-
-    dispatch.lua            -- coroutine based dispatcher
-
-This is a first try at a coroutine based non-blocking
-dispatcher for LuaSocket. Take a look at 'check-links.lua'
-and at 'forward.lua' to see how to use it.
-
-        check-links.lua                 -- HTML link checker program
-
-This little program scans a HTML file and checks for broken
-links. It is similar to check-links.pl by Jamie Zawinski,
-but uses all facilities of the LuaSocket library and the Lua
-language. It has not been thoroughly tested, but it should
-work. Just run
-
-        lua check-links.lua [-n] {<url>} > output
-
-and open the result to see a list of broken links. Make sure
-you check the '-n' switch. It runs in non-blocking mode,
-using coroutines, and is MUCH faster!
-
-    forward.lua             -- coroutine based forward server
-
-This is a forward server that can accept several connections
-and transfers simultaneously using non-blocking I/O and the
-coroutine-based dispatcher. You can run, for example
-
-    lua forward.lua 8080:proxy.com:3128 
-
-to redirect all local conections to port 8080 to the host 
-'proxy.com' at port 3128.
-
-    unix.c and unix.h
-
-This is an implementation of Unix local domain sockets and
-demonstrates how to extend LuaSocket with a new type of
-transport. It has been tested on Linux and on Mac OS X.
-
-Good luck,
-Diego.
