This is IMHO false in that "-?" is >a valid option to display the usage string(s). "-?" is an invalid option that can be (ab)used to display the usage message. It is clearly invalid for the i4b programs because none of the i4b man pages document it :-). Documenting it in all man pages wouldn't be useful. getopt actually says that "-?" is an illegal option.
