    - This release by PFIG -> update source URL
    - Package upstream's LICENSE file
    - Update dependencies as per upstream
    - Exclude s3cl script for now as we can't satisfy its dependencies
    - Drop %defattr, redundant since rpm 4.4
    - Use %{_fixperms} macro rather than our own chmod incantation
    - Allow for a future in which we might ship manpages compressed with something
      other than gzip
