+This directory contains some sample programs using
+LuaSocket. This code is not supported.
+
+ listener.lua -- socket to stdout
+ talker.lua -- stdin to socket
+
+listener.lua and talker.lua are about the simplest
+applications you can write using LuaSocket. Run
+
+ 'lua listener.lua' and 'lua talker.lua'
+
+on different terminals. Whatever you type on talk.lua will
+be printed by listen.lua.
+
+ lpr.lua -- lpr client
+
+This is a cool program written by David Burgess to print
+files using the Line Printer Daemon protocol, widely used in
+Unix machines. It uses the lp.lua implementation, in the
+etc directory. Just run 'lua lpr.lua <filename>
+queue=<printername>' and the file will print!
+
+ cddb.lua -- CDDB client
+
+This is the first try on a simple CDDB client. Not really
+useful, but one day it might become a module.
+
+ daytimeclnt.lua -- day time client
+
+Just run the program to retrieve the hour and date in
+readable form from any server running an UDP daytime daemon.
+
+ echoclnt.lua -- UDP echo client
+ echosrvr.lua -- UDP echo server
+
+These are a UDP echo client/server pair. They work with
+other client and servers as well.
+
+ tinyirc.lua -- irc like broadcast server
+
+This is a simple server that waits simultaneously on two
+server sockets for telnet connections. Everything it
+receives from the telnet clients is broadcasted to every
+other connected client. It tests the select function and
+shows how to create a simple server whith LuaSocket. Just
+run tinyirc.lua and then open as many telnet connections
+as you want to ports 8080 and 8081.
+
+Good luck,
+Diego.
