In gtk/gnome programs there are many built-in options provided bny those
libraries ; for example v1.02 says with "--help" something like this:

$ ghemical --help
Usage: ghemical [OPTION...]

GNOME options
  --disable-sound             Disable sound server usage
  --enable-sound              Enable sound server usage
  --espeaker=HOSTNAME:PORT    Host:port on which the sound server to use is
                              running
  --version

Help options
  -?, --help                  Show this help message
  --usage                     Display brief usage message

GTK options
  --gdk-debug=FLAGS           Gdk debugging flags to set
  --gdk-no-debug=FLAGS        Gdk debugging flags to unset
  --display=DISPLAY           X display to use
  --sync                      Make X calls synchronous
  --no-xshm                   Don't use X shared memory extension
  --name=NAME                 Program name as used by the window manager
  --class=CLASS               Program class as used by the window manager
  --gxid_host=HOST
  --gxid_port=PORT
  --xim-preedit=STYLE
  --xim-status=STYLE
  --gtk-debug=FLAGS           Gtk+ debugging flags to set
  --gtk-no-debug=FLAGS        Gtk+ debugging flags to unset
  --g-fatal-warnings          Make all warnings fatal
  --gtk-module=MODULE         Load an additional Gtk module

GNOME GUI options
  --disable-crash-dialog

Session management options
  --sm-client-id=ID           Specify session management ID
  --sm-config-prefix=PREFIX   Specify prefix of saved configuration
  --sm-disable                Disable connection to session manager

ghemical options
  -f, --file=filename         open file
  -i, --import=filename       import file as gpr

So I think it is OK to make the arguments a bit specific like this. Also
one can separate "open file" and "import file" using -f and -i (if
needed).

In v1.0x the arguments are added using "popt-gnome" or something like
that. The same stuff can be copied in v1.5x but does anyone know how it's
done with GTK2? Is the library still called "popt"?
