I need some further advise. I would go with either YAML or YAML::Store 
because then I'd get the manually editable file storage. However, I am 
searching the net for some examples but some have puzzled me even more 
(some use YAML.dump, others to_yaml and so on).

So I turned back to the pickaxe, which is a bit scarce for me regarding 
the YAML and I managed to get the objects stored in the .yml file, but I 
am not sure if I did it the right way to suite my purpose:

snipet:

#class definition above
card = Flashcard.new(name, source, target, part_of_speech, definition, 
example)

File.open("all_cards.yml", "a+") {|f| YAML.dump(card, f)}

This appends object after object. Here's the problem. How can I then 
access and display certain or all cards after loading the file:

card_file = YAML.load_file("all_cards.yml")

I've tried putsing the card_file with different parameters but I always 
get back the name of the first objec tin the storage.

Am I doing something wrong even when dumping objects?

And one last question, If I go with YAML and not YAML::Store can I 
delete certain card from the storage?

regards,
seba
