/**
 * Description
 * The GOption commandline parser is intended to be a simpler replacement for the
 * popt library. It supports short and long commandline options, as shown in the
 * following example:
 * testtreemodel -r 1 --max-size 20 --rand --display=:1.0 -vb -- file1 file2
 * The example demonstrates a number of features of the GOption commandline parser
 *  Options can be single letters, prefixed by a single dash. Multiple
 *  short options can be grouped behind a single dash.
 *  Long options are prefixed by two consecutive dashes.
 *  Options can have an extra argument, which can be a number, a string or a filename.
 *  For long options, the extra argument can be appended with an equals sign after the
 *  option name.
 *  Non-option arguments are returned to the application as rest arguments.
 *  An argument consisting solely of two dashes turns off further parsing, any remaining
 *  arguments (even those starting with a dash) are returned to the application as rest
 *  arguments.
 * Another important feature of GOption is that it can automatically generate nicely
 * formatted help output. Unless it is explicitly turned off with
 * g_option_context_set_help_enabled(), GOption will recognize the
 * --help, -?, --help-all
 * and --help-groupname options
 * (where groupname is the name of a GOptionGroup)
 * and write a text similar to the one shown in the following example to stdout.
 * Usage:
 *  testtreemodel [OPTION...] - test tree model performance
 * Help Options:
 *  -?, --help Show help options
 *  --help-all Show all help options
 *  --help-gtk Show GTK+ Options
 * Application Options:
 *  -r, --repeats=N Average over N repetitions
 *  -m, --max-size=M Test up to 2^M items
 *  --display=DISPLAY X display to use
 *  -v, --verbose Be verbose
 *  -b, --beep Beep when done
 *  --rand Randomize the data
 * GOption groups options in GOptionGroups, which makes it easy to
 * incorporate options from multiple sources. The intended use for this is
 * to let applications collect option groups from the libraries it uses,
 * add them to their GOptionContext, and parse all options by a single call
 * to g_option_context_parse(). See gtk_get_option_group() for an example.
 * If an option is declared to be of type string or filename, GOption takes
 * care of converting it to the right encoding; strings are returned in UTF-8,
 * filenames are returned in the GLib filename encoding.
 * Here is a complete example of setting up GOption to parse the example
 * commandline above and produce the example help output.
 * static gint repeats = 2;
 * static gint max_size = 8;
 * static gboolean verbose = FALSE;
 * static gboolean beep = FALSE;
 * static gboolean rand = FALSE;
 * static GOptionEntry entries[] =
 * {
         *  { "repeats", 'r', 0, G_OPTION_ARG_INT, repeats, "Average over N repetitions", "N" },
         *  { "max-size", 'm', 0, G_OPTION_ARG_INT, max_size, "Test up to 2^M items", "M" },
         *  { "verbose", 'v', 0, G_OPTION_ARG_NONE, verbose, "Be verbose", NULL },
         *  { "beep", 'b', 0, G_OPTION_ARG_NONE, beep, "Beep when done", NULL },
         *  { "rand", 0, 0, G_OPTION_ARG_NONE, rand, "Randomize the data", NULL },
 *  { NULL }
