No, there is no better way. There is a bunch of overloaded 
Gio::Application::add_main_option_entry() methods that take all the 
necessary parameters for creating a new Glib::OptionEntry. But there are 
no corresponding Glib::OptionGroup methods, and no Glib::OptionEntry 
constructor that takes all the necessary parameters (long_name, 
short_name, etc.).
