ar isn't too commonly used for things like distributions because it doesn't
have the same format in all versions of UNIX. For example, in 4.2BSD, (perhaps
somewhat earlier) ar was changed to be completey ascii rather than part binary
so that mailers could handle it. However, not everyone has 4.2, so shar was
invented since all you need to unpack it is the Bourne shell, which every UNIX
site has.
