+"""irclib -- Internet Relay Chat (IRC) protocol client library.
+
+This library is intended to encapsulate the IRC protocol at a quite
+low level. It provides an event-driven IRC client framework. It has
+a fairly thorough support for the basic IRC protocol, CTCP, DCC chat,
+but DCC file transfers is not yet supported.
+
+In order to understand how to make an IRC client, I'm afraid you more
+or less must understand the IRC specifications. They are available
+here: [IRC specifications].
+
+The main features of the IRC client framework are:
+
+ * Abstraction of the IRC protocol.
+ * Handles multiple simultaneous IRC server connections.
+ * Handles server PONGing transparently.
+ * Messages to the IRC server are done by calling methods on an IRC
+ connection object.
+ * Messages from an IRC server triggers events, which can be caught
+ by event handlers.
+ * Reading from and writing to IRC server sockets are normally done
+ by an internal select() loop, but the select()ing may be done by
+ an external main loop.
+ * Functions can be registered to execute at specified times by the
+ event-loop.
+ * Decodes CTCP tagging correctly (hopefully); I haven't seen any
+ other IRC client implementation that handles the CTCP
+ specification subtilties.
+ * A kind of simple, single-server, object-oriented IRC client class
+ that dispatches events to instance methods is included.
+
+Current limitations:
+
+ * The IRC protocol shines through the abstraction a bit too much.
+ * Data is not written asynchronously to the server, i.e. the write()
+ may block if the TCP buffers are stuffed.
+ * There are no support for DCC file transfers.
+ * The author haven't even read RFC 2810, 2811, 2812 and 2813.
+ * Like most projects, documentation is lacking...

+
+ When an IRC object has been instantiated, it can be used to create
+ Connection objects that represent the IRC connections. The
+ responsibility of the IRC object is to provide an event-driven
+ framework for the connections and to keep the connections alive.
+ It runs a select loop to poll each connection's TCP socket and
+ hands over the sockets with incoming data for processing by the
+ corresponding connection.
+
+ The methods of most interest for an IRC client writer are server,
+ add_global_handler, remove_global_handler, execute_at,
+ execute_delayed, process_once and process_forever.
+
+ Here is an example:
+
+ irc = irclib.IRC()
+ server = irc.server()
+ server.connect(\"irc.some.where\", 6667, \"my_nickname\")
+ server.privmsg(\"a_nickname\", \"Hi there!\")
+ irc.process_forever()
+
+ This will connect to the IRC server irc.some.where on port 6667
+ using the nickname my_nickname and send the message \"Hi there!\"
+ to the nickname a_nickname.

+ coming on a new socket. When new data arrives, the method

+ as first argument when the IRC object wants to receive a
