Offline Mode Design

* UPDATE: 18-April-2005

  We cannot take the approach outlined below of detecting which remote
  repositories are "really" offline, since offline mode is more of a behavior,
  and this will lead to counter-intuitive results. A different feature may exist
  unimplemented, which is to detect when the network is down and provide better
  feedback for that case. However, when offline mode is declared, nothing

                        try (InputStream in = Files.newInputStream(metadata.getPath())) {
                            versioning =
                                    new MetadataStaxReader().read(in, false).getVersioning();
