/**
 * @class KAboutData kaboutdata.h KAboutData
 *
 * This class is used to store information about a program or plugin.
 * It can store such values as version number, program name, home page, address
 * for bug reporting, multiple authors and contributors
 * (using KAboutPerson), license and copyright information.
 *
 * Currently, the values set here are shown by the "About" box
 * (see KAboutDialog), used by the bug report dialog (see KBugReport),
 * and by the help shown on command line (see KAboutData::setupCommandLine()).
 *
 * Porting Notes: Since KDE Frameworks 5.0, the translation catalog mechanism
 * must be provided by your translation framework to load the correct catalog
 * instead (eg: KLocalizedString::setApplicationDomain() for KI18n, or
 * QCoreApplication::installTranslator() for Qt's translation system). This
 * applies to the old setCatalogName() and catalogName() members. But see also
 * K4AboutData in kde4support as a compatibility class.
 *
 * Example:
 * Setting the metadata of an application using KAboutData in code also relying
 * on the KDE Framework modules KI18n and KDBusAddons:
 * @code
 * // create QApplication instance
 * QApplication app(argc, argv);
 * // setup translation string domain for the i18n calls
 * KLocalizedString::setApplicationDomain("foo");
 * // create a KAboutData object to use for setting the application metadata
 * KAboutData aboutData("foo", i18n("Foo"), "0.1",
 *                      i18n("To Foo or not To Foo"),
 *                      KAboutLicense::LGPL,
 *                      i18n("Copyright 2017 Bar Foundation"), QString(),
 *                      "https://www.foo-the-app.net");
 * // overwrite default-generated values of organizationDomain & desktopFileName
 * aboutData.setOrganizationDomain("barfoundation.org");
 * aboutData.setDesktopFileName("org.barfoundation.foo");
 *
 * // set the application metadata
 * KAboutData::setApplicationData(aboutData);
 * // in GUI apps set the window icon manually, not covered by KAboutData
 * // needed for environments where the icon name is not extracted from
 * // the information in the application's desktop file
 * QApplication::setWindowIcon(QIcon::fromTheme(QStringLiteral("foo")));
 *
 * // integrate with commandline argument handling
 * QCommandLineParser parser;
 * aboutData.setupCommandLine(&parser);
 * // setup of app specific commandline args
 * [...]
 * parser.process(app);
 * aboutData.processCommandLine(&parser);
 *
 * // with the application metadata set, register to the D-Bus session
 * KDBusService programDBusService(KDBusService::Multiple | KDBusService::NoExitOnFailure);
 * @endcode
