This library parses .b4u files, which are the native format of Before You Know It, a great flashcard application.
Many B4U files can be downloaded from http://www.byki.com/listcentral.html.
python readb4u.py [filename]
will read the file [filename] and create a KVTML (Parley) representation, with separate .OGG (sound) and .JPEG (image) files as available in the original .b4u file, in the folder output, with the name cards.kvtml.
To create HTML file look in the python code (last lines).
