Simple flashcard perl script

I think my friend Dan gave me a perl script a long time ago that was for Spanish flashcards. I have no idea where that is nowadays, but I decided to whip out a simple script. I think it is way simpler than Dan's version. There is no "grading" in this script. That is, there is no comparison with the answer you provide and the answer in the file. All you need to do to use this is to create a flashcard file. Each row contains the question and answer separated by a pipe.
