    \brief Qt 5 consists of essential modules, add-on modules, and tools.

    \section1 Qt Essentials

    Qt essentials define the foundation of Qt on all platforms. They are
    available on all supported development platforms and on the tested target
    platforms. They will remain source and binary compatible during Qt 5.

    Essential modules are general and useful for a majority of Qt applications.
    A module that is used for a special purpose is considered an add-on module
    even if it is available on all supported platforms.

    The following table lists the Qt essentials:

    \table 80%
    \header
        \li Module
        \li Description
    \row
        \li \l{Qt Core}
        \li Core non-graphical classes used by other modules.
    \row
        \li \l{Qt GUI}
        \li Base classes for graphical user interface (GUI) components.
            Includes OpenGL.
    \row
        \li \l{Qt Multimedia}
        \li Classes for audio, video, radio and camera functionality.
    \row
        \li \l{Qt Network}
        \li Classes to make network programming easier and more portable.
    \row
        \li \l{Qt QML}
        \li Classes for QML and JavaScript languages.
    \row
        \li \l{Qt Quick}
        \li A declarative framework for building highly dynamic applications
            with custom user interfaces.
    \row
        \li \l{Qt SQL}
        \li Classes for database integration using SQL.
    \row
        \li \l{Qt Test}
        \li Classes for unit testing Qt applications and libraries.
    \row
        \li \l{Qt WebKit}
        \li Classes for a WebKit2 based implementation and a new QML API.
            See also Qt WebKit Widgets in the add-on modules.
    \row
        \li \l{Qt WebKit Widgets}
        \li WebKit1 and QWidget-based classes from Qt 4.
    \row
        \li \l{Qt Widgets}
        \li Classes to extend Qt GUI with C++ widgets.
    \endtable

    If you use \l qmake to build your projects, the QtCore and QtGui
    modules are included by default. To link only against QtCore, add
    the following line to your \c .pro file:

    \snippet doc/src/snippets/code/doc_src_modules.pro 0

    On Windows, if you do not use \l qmake
    or other build tools such as CMake, you also need to link against
    the \c qtmain library.

    \section1 Qt Add-Ons

    Qt add-on modules bring additional value for specific purposes. These
    modules may only be available on some development platform for some target
    platforms. Some of them are included in the Qt releases on particular
    platforms. Each add-on module specifies its compatibility promise
    separately.

    The following table lists the Qt add-ons:

    \table 80%

    \title The qtmain Library
    \ingroup licensing
    \ingroup platform-specific
    \brief Describes the use and license of the qtmain helper library.

    qtmain is a helper library that enables the developer to write a
    cross-platform main() function on Windows.
    If you do not use \l qmake or other build tools such as CMake, then you
    need to link against the \c qtmain library.
