Version 1703 was commited by steve on 2010-09-24 20:13:42 +0100 (Fri, 24 Sep 2010) Test that command line arguments are valid by comparing them with the ones that are documented in the help options. If you need to override the check (during development for example) you can give options with a leading 'x-'. So --x-family-id is exactly the same as --family-id except that the check that family-id is valid is not performed. Documented some options that were not. By the way, the option help file is a complete jumble and needs re-organising.
