<para>
-
+ A calendar user agent (&CUA;) is a program that lets a user
+ manipulate a calendar. &Evolution; provides an attractive,
+ graphical calendar client that communicates with the &Evolution;
+ personal calendar server.
+ </para>
+
+ <para>
+ The &Evolution; calendar client just provides a view onto the
+ data that is stored and managed by the personal calendar server.
+ The calendar client does not perform direct manipulations on a
+ calendar's data; instead it offloads those requests to the
+ calendar server, which takes care of making the appropriate
+ modifications in the calendar and then notifies all the clients
+ about the changes.
+ </para>

+ <!-- Calendar Client Library -->
+
+ <sect1 id="client-lib">
+ <title>Calendar Client Library</title>
+
+ <para>
+ Communication between the personal calendar server and calendar
+ clients is defined by a set of &Bonobo; &CORBA; interfaces.
+ Clients can be written by implementing the client-side
+ <classname>Listener</classname> interface, which defines the
+ notification callbacks that the PCS uses to inform clients about
+ changes to the calendar.
+ </para>
+
+ <para>
+ As a convenience for &GTK; programmers, &Evolution; also
+ includes a library which provides a
+ <classname>CalClient</classname> class which can be used for
+ communication with the personal calendar server. Objects of
+ this class automatically contact the PCS when they are created.
+ <classname>CalClient</classname> provides functions to request
+ changes in the calendar, and it also emits signals when it gets
+ notification about changes from the PCS. This makes it easy and
+ convenient to write calendar clients for &Evolution; using
+ &GTK;.
+ </para>
+
+ <para>
+ The implementation of the <classname>CalClient</classname> class
+ simply wraps the &Evolution; &CORBA; interfaces for calendaring
+ with a familiar-looking &GTK; object. Calls to the
+ <classname>Listener</classname> interface get translated to
+ signal emissions from the <classname>CalClient</classname>, thus
+ shielding programmers from the details of the &CORBA;
+ interfaces.
