  --skip-backup                                  Disables backing up the project. This is not recommended unless the
                                                 project is in source control since this tool will make large changes
                                                 to both the project and source files.

                                                 could be an ExtensionManifest.json file, a directory containing an
                                                 ExtensionManifest.json file, or a zip archive containing an extension.
                                                 This option can be specified multiple times.
