+<H2><A NAME="s1">1. General information</A></H2>
+
+<H2><A NAME="ss1.1">1.1 What is Ivy?</A>
+</H2>
+
+<P>
+<P>Ivy is a software bus designed at CENA (France). A software bus is a system
+that allows software applications to exchange information with the illusion of
+broadcasting that information, selection being performed by the receiving
+applications. Using a software bus is very similar to dealing with events in a
+graphical toolkit: on one side, messages are emitted without caring about who
+will handle them, and on the other side, one decide to handle the messages that
+have a certain type or follow a certain pattern. Software buses are mainly aimed
+at facilitating the rapid development of new agents, and at managing a dynamic
+collection of agents on the bus: agents show up, emit messages and receive some,
+then leave the bus without blocking the others.
+<P>
+<H3>Architecture and principles</H3>
+
+<P>As opposed to other software buses, Ivy does not depend on a centralised
+server. Actually, Ivy is mostly a communication convention between processes,
+implemented through a collection of libraries in several languages.
+<P>
+<P>
+<P>From the programmer's point of view, Ivy is an information broadcasting
+channel. The main functions are:
+<P>
+<UL>
+<LI> connecting to a bus.<EM> Example: Ivy::start (-loopMode =>
+ 'local', -ivyBus => '2011', -appName => "toto" );</EM></LI>
+<LI> sending a message.<EM> Example: Ivy::sendMsgs ("HELLO WORLD")</EM></LI>
+<LI> bind a message pattern to a callback function.<EM> Example:
+ Ivy::bindRegexp ("^HELLO (.*)", [\&cb])</EM></LI>
+<LI> the main loop.<EM> MainLoop</EM></LI>
+</UL>
+<P>Ivy's
+decentralised connection scheme probably incurs limitations in terms of how many
+applications can be connected to an Ivy bus, but this simplifies management a
+lot. Basically, an Ivy bus is just a set of applications that decide to
+communicate together. The only conventions between these applications are:
+<OL>
+<LI> the use of the Ivy protocol (for obvious reasons)</LI>
+<LI> a bus address, made of a broadcast port number (a bit like a citizen band
+channel) and a set of networks addresses</LI>
+</OL>
+
+When an application wants to connect to a bus, it sends a broadcast message on the
+networks specified in the bus address, so that all applications present on those
+networks and listening on the specified port number connect to it. It then
+becomes part of the bus, and listens like the other ones.
+<P>The messages are exchanged in text format, and bindings are based on regular
+expressions with captures. If an application subscribes to
+<CODE>HELLO (.*)</CODE> and if another application emits the message <CODE>HELLO WORLD</CODE>, a
+callback will be called in the first application with <CODE>WORLD</CODE> as an argument.
+<P>
+<P>
+<H3>Using Ivy</H3>
+
+<P>You can use Ivy through applications that have been provided to you. This is the
+case for <CODE>ivyprobe</CODE>, an Ivy agent that allows you to examine the messages
+exchanged on a given bus and to send messages on that bus. You can refer to the
+web site <CODE>http:</CODE> for a list of available agents. However, what you will
+usually want to do is to develop your own applications. In order to do that you
+can use an Ivy connection kit, that is a library that implements Ivy.
+<P>
+<P>
+<P>Libraries that implement Ivy are available in the following environments:
+<UL>
+<LI> in C on Unix and Windows platforms, with its own communication library</LI>
+<LI> in C++ on Windows platforms</LI>
+<LI> in C++ on Unix platforms, integrated with the Uch communication library</LI>
+<LI> in C++ on Unix platforms, integrated with OpenInventor</LI>
+<LI> in C++ on Macintosh</LI>
+<LI> in Perl and in Perl/Tk</LI>
+<LI> integrated with Object Caml on Unix platforms</LI>
+<LI> in Scheme on Unix platforms</LI>
+<LI> in Java</LI>
+</UL>
+<P>
+<P>Connecting your application to an Ivy bus just consists in choosing the
+appropriate library, add the appropriate message emission and reception calls to
+your code, use the main loop provided in the library or make the necessary
+integrations, and get your code running!
+<P>
+<H2><A NAME="ss1.2">1.2 The Ivy Perl library</A>
+</H2>
+
+<P>The Ivy Perl library (aka Ivy-Perl or ivy-perl) is a Perl library that allows you to connect
+applications to an Ivy bus. You can use it to write applications in Perl or any
+other language that supports Perl extensions (Perl/Tk for instance). This guide documents how you can do
+that.
+<P>The Ivy Perl library is known to compile and work in WindowsNT and Linux
+environments. It should be easy to use on most Posix environments.
+<P>The Ivy Perl library was originally developed by Alexandre Bustico at CENA. It
+is maintained by the CENA-Toulouse team.

+
+<H2><A NAME="ss3.1">3.1 Initialization and main loop</A>
+</H2>
+
+<P>Initializing an Ivy agent with the Ivy-Perl library is done by calling function <CODE>Ivy::start</CODE>. In theory, initialization is then over. However in
+practice, as for any asynchronous communication or interaction library, nothing
+happens until your application has reached the main loop.
+<P>The Ivy Perl library provides two kind of main loop: a "local" loop
+ for perl code, and a "Tk" loop for perl-tk code.
+<P>Here is more details on <CODE>Ivy::start</CODE> function:
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+ Ivy::start(-loopMode => 'TK',
+ -ivyBus => '2011',
+ -appName => "TOTO",
+ -neededApp => "TITI",
+ -statusFunc => \&statusScan);
+
+</PRE>
+</CODE></BLOCKQUOTE>
+
+initializes and connects your application to the bus specified in <CODE>ivyBus</CODE>. The string provided
+should follow the convention described in section XX. Example: <CODE>"127:2010"</CODE>..
+<P>
+
+<BLOCKQUOTE><CODE>
+<PRE>
+MainLoop;
+</PRE>
+</CODE></BLOCKQUOTE>
+
+makes your application enter the main loop in which it will handle asynchronous
+communications and signals.
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+Ivy::stop ();
+</PRE>
+</CODE></BLOCKQUOTE>
+
+makes your application exit the main loop.
+<P>
+<P>
+<H2><A NAME="ss3.2">3.2 Emitting messages</A>
+</H2>
+
+<P>Emitting a message on an Ivy bus is much like printing a message on the standard
+output. However, do not forget that your message will not be emitted if Ivy has
+not been properly initialized and if you do not have a main loop of some sort
+running. To emit a message, use <CODE>IvySendMsg</CODE>, which works like <CODE>printf</CODE>:
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+Ivy::sendMsg ("...");
+</PRE>
+</CODE></BLOCKQUOTE>
+
+sends a message on the bus.
+<P>
+<P>
+<H2><A NAME="ss3.3">3.3 Subscribing to messages</A>
+</H2>
+
+<P>Subscribing to messages consists in binding a callback function to a message
+pattern. Patterns are described by regular expressions with captures. When a
+message matching the regular expression is detected on the bus, the callback
+function is called. The captures (ie the bits of the message that match the
+parts of regular expression delimited by brackets) are passed to the callback
+function much like options are passed to <CODE>main</CODE>. Use function <CODE>Ivy::bindRegexp</CODE>
+to bind a callback to a pattern.
+<BLOCKQUOTE><CODE>
+<PRE>
+Ivy::bindRegexp ("^HELLO WORLD", [\&Start]);
+</PRE>
+</CODE></BLOCKQUOTE>
+
+binds callback function <CODE>Start</CODE> to the regular expression specified by
+<CODE>regex_format</CODE>.
+<P>
+<BLOCKQUOTE><CODE>
+<PRE>
+Ivy::bindRegexp ("^HELLO WORLD", NULL);
+</PRE>
+</CODE></BLOCKQUOTE>
+
+deletes the binding.

+.SH NAME
+ivy-perl - a software bus library
+.SH SYNOPSIS
+Ivy-perl provides a useful set of Perl library functions for communicating between different
+processes through a software bus
+.SH DESCRIPTION
+Ivy is a software bus, ie a system that allows any software component to freely exchange data.
+The basic principle of a software bus is to ease the rapid implementation of new agents, and to manage a dynamic collection of agents on the bus: agents connect, send and receive messages, and disconnect without perturbing the overall functionment of the bus.
+Each time an application initializes a connection on the bus, a
+"ready" message is sent to all other applications already connected, and the
+list of the messages subscribed by this application is dispatched.
+The format for the messages is free.
+.nf
+The essential functions of Ivy are:
+.nf
+.I Connexion
+.nf
+.I Message sending
+.nf
+.I Message subscription
+.nf
+.I Main loop
+
+.SH FILES
+.I /usr/lib/perl5/site_perl/Ivy.pm
