24//! \class Client client.h
25//! \brief Communicates with the Jabber network. Start here.
26//!
27//! Client controls an active Jabber connection. It allows you to connect,
28//! authenticate, manipulate the roster, and send / receive messages and
29//! presence. It is the centerpiece of this library, and all Tasks must pass
30//! through it.
31//!
32//! For convenience, many Tasks are handled internally to Client (such as
33//! JT_Auth). However, for accessing features beyond the basics provided by
34//! Client, you will need to manually invoke Tasks. Fortunately, the
35//! process is very simple.
36//!
37//! The entire Task system is heavily founded on Qt. All Tasks have a parent,
38//! except for the root Task, and are considered QObjects. By using Qt's RTTI
39//! facilities (QObject::sender(), QObject::isA(), etc), you can use a
40//! "fire and forget" approach with Tasks.
41//!
42//! \code
43//! #include "client.h"
44//! using namespace Jabber;
45//!
46//! ...
47//!
48//! Client *client;
49//!
50//! Session::Session()
51//! {
52//! client = new Client;
53//! connect(client, SIGNAL(handshaken()), SLOT(clientHandshaken()));
54//! connect(client, SIGNAL(authFinished(bool, int, const QString &)), SLOT(authFinished(bool, int, const QString &)));
55//! client->connectToHost("jabber.org");
56//! }
57//!
58//! void Session::clientHandshaken()
59//! {
60//! client->authDigest("jabtest", "12345", "Psi");
61//! }
62//!
63//! void Session::authFinished(bool success, int, const QString &err)
64//! {
65//! if(success)
66//! printf("Login success!");
67//! else
68//! printf("Login failed. Here's why: %s\n", err.latin1());
69//! }
