+IRC Mod API
+===========
+
+This file documents the Minetest IRC mod API.
+
+Basics
+------
+
+In order to allow your mod to interface with this mod, you must add `irc`
+to your mod's `depends.txt` file.
+
+
+Reference
+---------
+
+irc:say([name,] message)
+Sends <message> to either the channel (if <name> is nil or not specified),
+or to the given user (if <name> is specified).
+Example:
+	irc:say("Hello, Channel!")
+	irc:say("john1234", "How are you?")
+
+irc:register_bot_command(name, cmdDef)
+	Registers a new bot command named <name>.
+	When an user sends a private message to the bot with the command name, the
+	command's function is called.
+	Here's the format of a command definition (<cmdDef>):
+		cmdDef = {
+			params = "<param1> ...",      -- A description of the command's parameters
+			description = "My command",   -- A description of what the command does. (one-liner)
+			func = function(user, args)
+				-- This function gets called when the command is invoked.
+				-- <user> is a user table for the user that ran the command.
+				--   (See the LuaIRC documentation for details.)
+				--   It contains fields such as 'nick' and 'ident'
+				-- <args> is a string of arguments to the command (may be "")
+				-- This function should return boolean success and a message.
+			end,
+		};
+	Example:
+		irc:register_bot_command("hello", {
+			params = "",
+			description = "Greet user",
+			func = function(user, param)
+				return true, "Hello!"
+			end,
+		});
+
+irc.joined_players[name]
+	This table holds the players who are currently on the channel (may be less
+	than the players in the game). It is modified by the /part and /join chat
+	commands.
+	Example:
+	if irc.joined_players["joe"] then
+		-- Joe is talking on IRC
+	end
+
+irc:register_hook(name, func)
+	Registers a function to be called when an event happens. <name> is the name
+	of the event, and <func> is the function to be called. See HOOKS below
+	for more information
+	Example:
+	irc:register_hook("OnSend", function(line)
+		print("SEND: "..line)
+	end)
+
+This mod also supplies some utility functions:
+
+string.expandvars(string, vars)
+	Expands all occurrences of the pattern "$(varname)" with the value of
+	'varname' in the <vars> table. Variable names not found on the table
+	are left verbatim in the string.
+	Example:
+	local tpl = "$(foo) $(bar) $(baz)"
+	local s = tpl:expandvars({foo=1, bar="Hello"})
+	assert(s == "1 Hello $(baz)") 
+
+In addition, all the configuration options decribed in `README.txt` are
+available to other mods, though they should be considered read-only. Do
+not modify these settings at runtime or you might crash the server!
+
+
+Hooks
+-----
+
+The `irc:register_hook` function can register functions to be called
+when some events happen. The events supported are the same as the LuaIRC
+ones with a few added (mostly for internal use).
+See src/LuaIRC/doc/irc.luadoc for more information.

+IRC Mod for Minetest
+====================
+
+Introduction
+------------
+This mod is just a glue between IRC and Minetest. It provides two-way
+ communication between the in-game chat, and an arbitrary IRC channel.
+
+The forum topic is at http://minetest.net/forum/viewtopic.php?id=3905
+
+ 
+Installing
+----------
+
+Quick one line install for linux:
+
+	cd <Mod directory> && git clone https://github.com/kaeza/minetest-irc.git irc && cd irc && git submodule update --init
+
+Please change `<Mod directory>` to fit your installation of minetest.
+For more information, see [the wiki](http://wiki.minetest.net/Installing_mods).
+
+The Minetest IRC mod uses submodules, therefore you will have to run
+`git submodule init` when first installing the mod, and `git submodule update`
+every time that a submodule is updated.  These steps can be combined as
+`git submodule update --init`.
+
+The Minetest IRC mod also requires LuaSocket.  This can be installed using your
+package manager on many distributions, for example on Arch Linux:
+
+	# pacman -S lua51-socket
+
+
+Settings
+--------
+All settings are changed in `minetest.conf`. If any of these settings
+are not set, the default value is used.
+
+  * `irc.server` (string, default "irc.freenode.net")
+	This is the IRC server the mod connects to.
+
+  * `irc.channel` (string, default "##mt-irc-mod")
+	The IRC channel to join.
+
+  * `irc.interval` (number, default 2.0)
+	This prevents the server from flooding. It should be at
+	least 2.0 but can be higher. After four messages this much
+	time must pass between folowing messages.
+
+  * `irc.nick` (string, default "MT-FFFFFF")
+	Nickname used as "proxy" for the in-game chat. 
+	'F' stands for a random base-16 number.
+
+  * `irc.password` (string, default "")
+	Password to use when connecting to the server.
+
+  * `irc.NSPass` (string, default nil)
+	NickServ password. Don't use this if you use SASL authentication.
+
+  * `irc.sasl.pass` (string, default nil)
+	SASL password, same as nickserv password.
+	You should use this instead of NickServ authentication
+	if the server supports it.
+
+  * `irc.sasl.user` (string, default `irc.nick`)
+	The SASL username. This should normaly be set to your main NickServ account name.
+
+  * `irc.debug` (boolean, default false)
+	Whether to output debug information.
+
+  * `irc.disable_auto_connect` (boolean, default false)
+	If false, the bot is connected by default. If true, a player with
+	the 'irc_admin' privilege has to use the /irc_connect command to
+	connect to the server.
+
+  * `irc.disable_auto_join` (boolean, default false)
+	If false, players join the channel automatically upon entering the
+	game. If true, each user must manually use the /join command to
+	join the channel. In any case, the players may use the /part
+	command to opt-out of being in the channel.
+
+  * `irc.send_join_part` (boolean, default true)
+	Determines whether to send player join and part messages to the channel.
+
+Usage
+-----
+
+Once the game is connected to the IRC channel, chatting using the 'T' or
+F10 hotkeys will send the messages to the channel, and will be visible
+by anyone. Also, when someone sends a message to the channel, that text
+will be visible in-game.
+
+Messages that begin with `[off]` from in-game or IRC are not sent to the
+other side.
+
+This mod also adds a few chat commands:
+
+  * `/irc_msg <nick> <message>`
+	Sends a private message to a IRC user.
+
+  * `/join`
+	Join the IRC chat.
+
+  * `/part`
+	Part the IRC chat.
+
+  * `/irc_connect`
+	Connect the bot manually to the IRC network.
+
+  * `/irc_disconnect`
+	Disconnect the bot manually from the IRC network (this does not
+	shutdown the game).
+
+  * `/irc_reconnect`
+	Equivilant to `/irc_disconnect` followed by `/irc_connect`.
+
+You can also send private messages from IRC to in-game players.
+
+To do it, you must send a private message to the bot (set with
+the `irc.nick` option above), in the following format:
+
+	@playername message
+
+For example, if there's a player named `mtuser`, you can send him/her
+a private message from IRC with:
+
+	/msg server_nick @mtuser Hello!
+
+To avoid possible misunderstandings (since all in-game players use the
+same IRC user to converse with you), the "proxy" user will reject any
+private messages that are not in that format, and will send back a
+nice reminder as a private message.
+
+The bot also supports some basic commands, which are invoked by sending
+a private message to it. Use `!list` to get a list of commands, and
+`!help <command>` to get help about a specific command.
+
+
+Thanks
+------
+
+I'd like to thank the users who supported this mod both on the Minetest
+Forums and on the #minetest channel. In no particular order:
+
+0gb.us, ShadowNinja, Shaun/kizeren, RAPHAEL, DARGON, Calinou, Exio,
+vortexlabs/mrtux, marveidemanis, marktraceur, jmf/john\_minetest,
+sdzen/Muadtralk, VanessaE, PilzAdam, sfan5, celeron55, KikaRz,
+OldCoder, RealBadAngel, and all the people who commented in the
+forum topic. Thanks to you all!
