    var entry: CkoZipEntry? = zip.GetEntryByName("hamlet.xml")
    // Assume entry is non-null.  If GetEntryByName failed
    // to find the entry, it returns a null reference.
    entry.FileName = "hamlet2.xml"
    entry = nil

    entry = zip.GetEntryByName("helloWorld.pl")
    entry.FileName = "hw.pl"
    entry = nil

    // Now unzip to the "test" subdirectory, under our current
    // working directory:
    var numFilesUnzipped: Int = zip.Unzip("test").intValue
    if numFilesUnzipped < 0 {
        print("\(zip.LastErrorText)")
        return
    }

    // The filenames within the .zip are unchanged, but it unzipped
    // test/hw.pl and test/hamlet2.xm
