I tried to change to OCR-B or Inconsolata
but getting that to work with enscript is not easy, as you have to find and
install afm and pfb into the correct directories. This goes a lot deeper than
just installing packages provided by whatever disto you are using.
So I think that this would move the bar for a possible user of paperbackup.py
higher than I want to.

Can you recommend a tool to create a short checksum (crc32?) for each line?
Ideally it is a tool or combination of tools already deployed widely, like sed
and sort I used in paperrestore. This would make the checksums still usable
even when the source to paperbackup.py isn't available anymore.
