blocks/starter_block
*
* Block starter:
* Import a PDF page containing blocks and fill text and image
* blocks with some data. For each addressee of the simulated
* mailing a separate page with personalized information is
* generated.
* A real-world application would of course fill the blocks with data
* retrieved from some external data source.
*
* Required software: PPS 9
* Required data: input PDF, image
