    \title Open Source Versions of Qt
    \ingroup licensing
    \brief Information about the license and features of the Open Source Edition.

    Free (or open source) software is software that comes with a license
    that gives users certain rights. In particular the right to use the
    software, to modify it, to obtain its source, and to pass it on (under
    the same terms). Notice that the term "free" is about rights, not
    money. The Free Software Foundation (creators of the GNU GPL) speaks
    of free in this context as in "free speech", not as in "no cost".

    Qt Software supports the free software concept by providing the Qt Open Source
    Edition, which is licensed under the \l{GNU General Public License (GPL)}
    (version 3) and the \l{GNU Lesser General Public License (LGPL)} (version 2.1).
    You can use this edition of Qt to create and distribute software with licenses
    that are compatible to these free software licenses.

    The support of open source with the Open Source Versions of Qt has enabled large
    successful software projects like KDE to thrive, with thousands of developers
    around the world using open source versions of Qt at no cost to themselves. With
    the release of Qt 4, open source versions of Qt became available for Unix/X11,
    Mac OS X, and Windows platforms.

    The Open Source Edition can be downloaded from the \l{Downloads}{Qt website}.

    Please refer to the online \l{License FAQ} for answers to frequently asked
    questions on open source licensing and its implications.

    More information on Free and Open Source software is available online:
