pdfsandwich - Automatic OCR with text injection into PDFs

[Petter Reinholdtsen]

I just came across <URL: http://www.tobias-elze.de/pdfsandwich/ >, which
seem interesting to us:

  pdfsandwich generates "sandwich" OCR pdf files, i.e. pdf files which
  contain only images (no text) will be processed by optical character
  recognition (OCR) and the text will be added to each page invisibly
  "behind" the images.

I know some copier/scanner machines do this, but now we can do it in
batch. :)
