-    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

-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
