#This Script is in the public domain
#Feedback welcome
#
#This script creates a pdf file with pdflatex
#for creating a memory-game. 
#Put the images with extension .jpg in a directory called images
#For each image create .txt file (foo.jpg --> foo.txt) containing
#a short description.
#The script creates a memory-card for each image.
#Print it twice, cut the cards, stick them on thick paper.
#A nice present for you grandmother
#The text for images in portait format need to start with "x"
