hi, i 'm trying to write a cards game in nothing but scheme. i found the very useful games/cards package, which allows to shuffle, drag and drop cards,... the problem is that i have to redefine the cards (the cards game doesn't use the normal 52 cards, but my own, new defined, cards).
does anyone has an idea, if i can make some changes in this games/cards thing? for the moment, i even can't find this package on my computer!
