"""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...

"""Class that handles one or several IRC server connections.
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.

Optional arguments are fn_to_add_socket, fn_to_remove_socket
and fn_to_add_timeout. The first two specify functions that
will be called with a socket object as argument when the IRC
object wants to be notified (or stop being notified) of data
coming on a new socket. When new data arrives, the method
process_data should be called. Similarly, fn_to_add_timeout
is called with a number of seconds (a floating point number)
as first argument when the IRC object wants to receive a
notification (by calling the process_timeout method). So, if
e.g. the argument is 42.17, the object wants the
process_timeout method to be called after 42 seconds and 170
milliseconds.
The three arguments mainly exist to be able to use an external
main loop (for example Tkinter's or PyGTK's main app loop)
instead of calling the process_forever method.
An alternative is to just call ServerConnection.process_once()
once in a while.
