something like this maybe?...
GOptionEntry options[] = {
{ "verbose", 0, 0, G_OPTION_ARG_NONE, &gbverbose, "Add verbose output to standard log", NULL },
{ "version", 0, 0, G_OPTION_ARG_NONE, &gbversion, "Print version information on standard output", NULL },
{ "parse", 0, 0, G_OPTION_ARG_NONE, &gcparse, "Parse the program, print errors on standard error", NULL },
{ "scan", 0, 0, G_OPTION_ARG_NONE, &gscan, "Scan the file", NULL }
{ "f", 0, 0, G_OPTION_ARG_FILENAME, &filename, "File name", NULL }
{ NULL }
};
or just skip the 'f' option and throw an error if either parse or scan
are used but no filename is given.
