No way to visually group command line options in Gio::Application (g_application_add_option_group not wrapped)
Applications of a certain size have many command line options, so grouping them logically is necessary.
g_application_add_option_group for this, which allows to add a
GOptionGroup to the commandline handling of application and would achieve the desired result.
Unfortunately glibmm does not seem to wrap this function. If I understood the linked bug properly this was mainly to avoid having to deal with
However the required functionality seems to be missing because of this unless there is any recommendable possibility to implement this that I overlooked.
