// the fixtures have some weird stuff that is painful
// to include directly in the repo for various reasons.
//
// So, unpack the fixtures with the system tar first.
//
// This means, of course, that it'll only work if you
// already have a tar implementation, and some of them
// will not properly unpack the fixtures anyway.
//
// But, since usually those tests will fail on Windows
// and other systems with less capable filesystems anyway,
// at least this way we don't cause inconveniences by
// merely cloning the repo or installing the package.
