    .epilog '''
      Format of YAML file in case you want to update multiple pages (supports multidoc):

      ```yaml
      page: SOME:Page Title
      newBody: "new body"
      ---
      -
        page: 1234567
        title: "new title"
        version: 4          # current version
      -
        page: SOME:Page Title
        newBody: "<p>some body</p>"
      ```

      Page is always resolved to ID and missing fields are filled from the queried
      current version.  If you specify the version you are sure, that change will
      not be performed in case there was an edit in between to create a newer
      version.
