# Set up flash card sets in $HOME/.flashcards/filename
# where each filename defines an array called cards, like this:
# cards = [
#     [ "1", "one" ],
#     [ "2", "two" ],
# ]
# It will look for .flashcards/all as a default, or you can pass
# the filename as an argument, e.g. flashcard shortlist will
# use the cards defined in $HOME/.flashcard/shortlist.
