When you say 'tree', does that imply something like the 'tree' command output

Root
|_next_to_root
  |_next_to_next_to_root

Along those lines? Just a little clarification please... :-)

UPDATEAssuming above is about right... Took a moment to see what search might bring up...

Here is one result. Scroll down just a bit...

Hope that is helpful...
