    \title Additional Modules

    \e{Qt Add-On} modules bring additional value for specific purposes. These
    modules may only be available on some development platform. Many add-on
    modules are either feature-complete and exist for backwards compatibility,
    or are only applicable to certain platforms. Each add-on module specifies
    its compatibility promise separately.

    The Qt installers include the option of downloading the add-ons. For more
    information, visit the \l{Getting Started with Qt} page.
