        std::cout << zip.lastErrorText() << "\r\n";
        return;
    }

    entry.put_FileName("hw.pl");

    // Now unzip to the "test" subdirectory, under our current
    // working directory:
    int numFilesUnzipped = zip.Unzip("test");
    if (numFilesUnzipped < 0) {
        std::cout << zip.lastErrorText() << "\r\n";
        return;
    }

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