(Swift 3,4,5...) Create TAR BZ2 Compressed Archive (.tar.bz2, .tbz, .tbz2, .tb2)

Demonstrates how to create a compressed TAR archive containing an entire directory tree. This example creates a compressed archive using BZip2 compression. The typical file extensions used are .tar.bz2, .tbz2, .tbz, or .tb2.

    let tar = CkoTar()!

    // The TAR component will produce a  GNU tar 1.13.x format
    // archive by default.
    // It is also possible to create PAX -- POSIX 1003.1-2001 format
    // or USTAR -- POSIX 1003.1-1988 format.
    // Set the WriteFormat property to "gnu", "pax", or "ustar" to
    // choose the output TAR format:
    tar.writeFormat = "gnu"

    // Add a directory tree to be included in the output TAR archive:
    var success: Bool = tar.addDirRoot("/Users/chilkat/temp/abc123")
    if success != true {
        print("\(tar.lastErrorText!)")
        return
    }

    // Create the compressed TAR archive using BZip2.
    // Note: You may use UNC paths, absolute, or relative paths.
    success = tar.writeBz2("/Users/chilkat/testData/tar/abc123.tar.bz2")
    if success != true {
        print("\(tar.lastErrorText!)")
        return
    }

    print("Success.")
