/* Note: Command-line argument parsing for Gtk+ applications has
* evolved. Gtk+-2.4 and before use the "popt" method. We use that
* here for compatibility. Gnome-2.4 has a way of wrapping the "popt"
* method (using GNOME_PARAM_POPT_CONTEXT). Its advantages are that
* it adds help messages for sound and the crash-dialog. Its
* disadvantages are that it prints a rather messy usage message
* with lots of '?v's and it doesn't allow us to describe the
* [DATAFILE] argument in the usage. Weighing those factors, we're
* just going to use popt directly.
*
* Glib-2.6 introduced GOptionContext and GOptionGroup, which are
* meant to replace popt usage. In Gnome-2.14, the popt usage is
* offically deprecated, and the GNOME_PARAM_GOPTION_CONTEXT can be
* used.
