  * This class is used to store information about a person or developer.
  * It can store the person's name, a task, an email address and a
  * link to a home page. This class is intended for use in the
  * KAboutData class, but it can be used elsewhere as well.
  * Normally you should at least define the person's name.
  * Creating a KAboutPerson object by yourself is relatively useless,
  * but the KAboutData methods KAboutData::authors() and KAboutData::credits()
  * return lists of KAboutPerson data objects which you can examine.
  *
  * Example usage within a main(), retrieving the list of people involved
  * with a program and re-using data from one of them:
  *
  * @code
  * KAboutData about("khello", i18n("KHello"), "0.1",
  *                   i18n("A KDE version of Hello, world!"),
  *                   KAboutLicense::LGPL,
  *                   i18n("Copyright (C) 2014 Developer"));
  *
  * about.addAuthor(i18n("Joe Developer"), i18n("developer"), "joe@host.com", 0);
  * QList<KAboutPerson> people = about.authors();
  * about.addCredit(people[0].name(), people[0].task());

  *
  * 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);

      * @note If your program should work as a D-Bus activatable service, the base name
      * of the D-Bus service description file or of the desktop file you install must match
      * the D-Bus "well-known name" for which the program will register.
      * For example, KDBusService will use a name created from the reversed organization domain
      * with the component name attached, so for an organization domain "bar.org" and a
      * component name "foo" the name of an installed D-Bus service file needs to be
      * "org.bar.foo.service" or the name of the installed desktop file "org.bar.foo.desktop"
      * (and the desktopFileName property accordingly set to "org.bar.foo").
      * For still supporting the deprecated start of services via KToolInvocation,
      * the desktop file needs to have an entry with the key "X-DBUS-ServiceName"
      * and a value which matches the used D-Bus "well-known name" as just described,
      * so with the above used values it needs a line "X-DBUS-ServiceName=org.bar.foo"
