You can have various key combinations: $hash->{key1}{key2}.....
where key1 could be the root portion and key2 a subset,
etc
Just remember you need to be able to get your head around what
you do. You can even have arrays associated with the hash data, so it
can be very complex, but make sure that you know what you are after or
be able to ask the questions that will give you a good understanding of
what you need.
