Actually, the oggz-comment.c on my computer has
void help() {
printf("Usage: oggz-comment filename [options] tagname=tagvalue
...\n");
printf("Options:\n");
printf("\t-h, --help\t\tDisplay this message\n");
printf("\t-v, --version\t\tOutput version information\n");
printf("\t-c, --clear\t\tClear comments before editing\n");
printf("\t-o [output file]\tcreate new copy with edited
comments\n");
printf("\t-t [content type]\tedit comments for this content type
only\n");
printf("\t-s [serial number]\tedit comments for this serial number
only\n");
printf("\t-a\t\t\tedit comments for all bitstreams\n\n");
}
It definitely needs some serious revision, since, compared to other
things in liboggz, this one sticks out like a swollen, festering sore
thumb. Sorry 'bout that.
