Well, this is the wrong list for it but... tar should include
a protocal version number in its header so that you could
interchange files with different versions and be upwardly
compattible. But I shouldn't start that thread here - and
for all I know (and I know nothing about tar internals) it
already has a protocal number as part of its spec.
