Start here. +//! +//! Client controls an active Jabber connection. It allows you to connect, +//! authenticate, manipulate the roster, and send / receive messages and +//! presence. It is the centerpiece of this library, and all Tasks must pass +//! through it. +//! +//! For convenience, many Tasks are handled internally to Client (such as +//! JT_Auth). However, for accessing features beyond the basics provided by +//! Client, you will need to manually invoke Tasks. Fortunately, the +//! process is very simple. +//! +//! The entire Task system is heavily founded on Qt. All Tasks have a parent, +//! except for the root Task, and are considered QObjects. By using Qt's RTTI +//! facilities (QObject::sender(), QObject::isA(), etc), you can use a +//! "fire and forget" approach with Tasks. +//! +//! \code +//! #include "client.h" +//! using namespace Jabber; +//! +//! ... +//! +//! Client *client; +//! +//!
