descript: convert scripture decks to tunnel decks
usage: descript <deck file>

This prints to stdout so you can do something like

descript deck > deck2
diff deck deck2

and ensure that it worked

This script assumes TSV splitting - edit the $DELIM variable at the top
if you are using something else
