Body: <p>I converted my docx into a epub file using Calibre but Smashwords is saying that the META-INF/calibre_bookmarks.txt file is not listed in the manifest.</p>
  
  <p>Below is their full explanation. Does anyone know how to easily add this? </p>
  
  <pre><code>File 'META-INF/calibre_bookmarks.txt' in EPUB not listed in manifest!
  Your .epub file is missing one or more elements in its manifest. A complete manifest is required for distribution to Apple. Here's how Wikipedia (http://en.wikipedia.org/wiki/EPUB) defines "Manifest":"The manifest element lists all the files contained in the package. Each file is represented by an item element, and has the attributes id, href, media-type. All XHTML (content documents), stylesheets, images or other media, embedded fonts, and the NCX file should be listed here."
