+-- Prosody Example Configuration File
+--
+-- Information on configuring Prosody can be found on our
+-- website at http://prosody.im/doc/configure
+--
+-- Tip: You can check that the syntax of this file is correct
+-- when you have finished by running: luac -p prosody.cfg.lua
+-- If there are any errors, it will let you know what and where
+-- they are, otherwise it will keep quiet.
+--
+-- The only thing left to do is rename this file to remove the .dist ending, and fill in the
+-- blanks. Good luck, and happy Jabbering!
+
+
+---------- Server-wide settings ----------
+-- Settings in this section apply to the whole server and are the default settings
+-- for any virtual hosts
+
+-- This is a (by default, empty) list of accounts that are admins
+-- for the server. Note that you must create the accounts separately
+-- (see http://prosody.im/doc/creating_accounts for info)
+-- Example: admins = { "user1@example.com", "user2@example.net" }
+admins = { "alex@jabber.n39.eu", "tux@jabber.n39.eu" }

+-- For more information see: http://prosody.im/doc/libevent
+use_libevent = true;
+
+-- This is the list of modules Prosody will load on startup.
+-- It looks for mod_modulename.lua in the plugins folder, so make sure that exists too.
+-- Documentation on modules can be found at: http://prosody.im/doc/modules

+
+	-- Not essential, but recommended

+		"vcard"; -- Allow users to set vCards
+	
+	-- These are commented by default as they have a performance impact
+		"privacy"; -- Support privacy lists
+		"compression"; -- Stream compression (Debian: requires lua-zlib module to work)
+
+	-- Nice to have
+		"version"; -- Replies to server version requests
+		"uptime"; -- Report how long server has been running
+		"time"; -- Let others know the time here on this server
+		"ping"; -- Replies to XMPP pings with pongs
+		"pep"; -- Enables users to publish their mood, activity, playing music and more
+		"register"; -- Allow users to register on this server using a client and change passwords
+
+	-- Admin interfaces
+		"admin_adhoc"; -- Allows administration via an XMPP client that supports ad-hoc commands
+		"admin_telnet"; -- Opens telnet console interface on localhost port 5582
+	
+	-- HTTP modules
+		--"bosh"; -- Enable BOSH clients, aka "Jabber over HTTP"
+		--"http_files"; -- Serve static files from a directory over HTTP
+
+	-- Other specific functionality
+		"posix"; -- POSIX functionality, sends server to background, enables syslog, etc.
+		--"groups"; -- Shared roster support
+		"announce"; -- Send announcement to all online users
+		--"welcome"; -- Welcome users who register accounts
+		"watchregistrations"; -- Alert admins of registrations
+		--"motd"; -- Send a message to users when they log in
+		--"legacyauth"; -- Legacy authentication. Only used by some old clients and bots.

+
+---Set up an external component (default component port is 5347)
+--
+-- External components allow adding various services, such as gateways/

+--
+--Component "gateway.example.com"
+--	component_secret = "password"
+
+------ Additional config files ------
+-- For organizational purposes you may prefer to add VirtualHost and
+-- Component definitions in their own config files. This line includes
+-- all config files in /etc/prosody/conf.d/
+
+Include "conf.d/*.cfg.lua"
