<h2>License of this Application and Source Code Access</h2>
<p>This application is free software, it is licensed under the terms and conditions of the GNU General Public License (GPL) as published by the Free Software Foundation, either version 3 of the GPL or — at your option — any later version.</p>
<p>This application consists of two parts: The Fp311Online Client Application and the Fp311Online Common Library with shared code for both the server and the client.</p>
<p>The source code for both parts can be obtained from the GitLab source code management tool of Institut für Experimentalphysik I:</p>
<h2>Open Source Frameworks used by this Application</h2>
<p>This application (and its common library) use code from other open source projects. Under their respective licenses, you have the right to access their source code and distribute unmodified as well as modified versions of them.</p>
<p>Qt (<a href="https://qt.io">https://qt.io</a>) is a cross-platform C++ framework developed by “The Qt Company” to build graphical applications. It is used in this software to create the user interface and to handle the client/server communication via the websockets protocol.</p>
<p>This application uses the modules “Core“, “Gui“, “Widgets“, “Network”, and “WebSockets“ from Qt. All of them are licensend under the GNU Lesser General Public License (LGPL), version 3.</p>
<p>If you use the Flatpak build of this application, Qt is not shipped with the application, but is part of the Flatpak runtime environment <tt>org.kde.Platform</tt>, see <a href="https://docs.flatpak.org/en/latest/available-runtimes.html">https://docs.flatpak.org/en/latest/available-runtimes.html</a> for details. The source code can be accessed on the GitLab installation of the KDE Project: <a href="https://invent.kde.org/packaging/flatpak-kde-runtime">https://invent.kde.org/packaging/flatpak-kde-runtime</a> and <a href="https://invent.kde.org/qt/qt">https://invent.kde.org/qt/qt</a></p>
<p>If you compiled this application from source, the Qt libraries and header files installed on your computer are used. Please consult your distributor for access to the source code of these libraries.</p>
<h3>ROOT</h3>
<p>ROOT (<a href="https://root.cern">https://root.cern</a>) is a data analysis framework developed by <a href="https://home.cern">CERN</a>. It is used in this application to generate the events on the server and display and fit the histogram on the client.</p>
<p>ROOT is licensed under the terms of the GNU Lesser General Public License (LGPL), version 2.1 or later.</p>
<p>The Flatpak build of this application contains the ROOT libraries and its header files. This project has a modified version of ROOT to make it run (better) inside the Flatpak sanbox. The source code of this modified version is available on the GitLab of Institut für Experimentalphysik I: <a href="https://gitlab.ep1.rub.de/fp311online/cern-root">https://gitlab.ep1.rub.de/fp311online/cern-root</a></p>
<p>The source code of the original ROOT project can be found on GitHub: <a href="https://github.com/root-project/root">https://github.com/root-project/root</a></p>
<p>When run outside of the Flatpak sandbox, this application can also use the unmodified version of ROOT. Inside the sanbox, unmodified versions should work, but the startup performance may be reduced.</p>
<p>If you compile this application from source, you can select whether to use a ROOT installation already present on your computer or let the build system of this application build its own ROOT. In the latter case, the source code is downloaded from the aforementioned source at the Institut für Experimentalphysik I GitLab.</p>
