I'd rather put `exit 1' right in invalid option case, instead of jumping to help. Because help output is huge, and it is often difficult to see the error message. At max, at the error case, the script can output something like, `for a list of valid options, run $0 --help'. Here and for qemu-img case. Do you not agree? Thanks, /mjt
