Well, either this or Noah's method has the disadvantage that not
everyone will get the benefit of the tests, and that those who wish to
get that benefit must install more stuff. But, all three of the
computers I have within arm's reach (yeah, I might have a problem)
have Archive::Tar installed, so maybe it's not a big concern in
practice. I am slightly inclined to think that the perl package
approach might be better than shell commands because perhaps it is
more likely to work on Windows, but I'm not positive.
