Just compare how it was (kconf_update):

And how it looks now:

> parser->addVersionOption("1.1");
> parser->addHelpOption(QCoreApplication::translate("main", "KDE Tool 
> for updating user configuration files"));

It's really bad to make programmers write an excessive code like 
"QCommandLineOption(QStringList() <<".
It's even worse in uic and moc:
> QCommandLineOption dependenciesOption(QStringList() << 
> QStringLiteral("d") << QStringLiteral("dependencies"));
> dependenciesOption.setDescription(QStringLiteral("Display the 
> dependencies."));
> parser.addOption(dependenciesOption);

Why??? It must be like that: options.add("d").add("dependencies", 
QStringLiteral("Display the dependencies."));
I feel like I'm in a nightmare. What's the point to invent a bicycle 
that's worse than the existing one?
