I think it would be surprising to have two GNU-style long options so I 
think we should pick one.  "--dir" seems okay to me and is consistent 
with the other the other JDK tools that extract to a directory (although 
those tools might not be well known). If you prefer "--directory" then I 
think we'll should add it to the other tools and hide "--dir" from the 
usage output.
