eract provides the transparent OCR fallback support, if the document
      is a simple scan, and the file doesn't contain any embedded text.

      Because documents need to be in PDF format before any metadata, text,
      or images are extracted, it's faster to use <tt>docsplit pdf</tt>
      to convert it up front, if you're planning to run more than one extraction.
      Otherwise Docsplit will write out the PDF version to a temporary file before
      proceeding with each command.
