This is an addon for Anki (http://ankisrs.net/) to convert Vocabulary Builder flashcards from an Amazon Kindle into an Anki deck.
It is still very much a work in progress and a learning opportunity for me. Please don't hesitate to share your thoughts or advice.
It does require you to install the Wordnik api python client (for now).
To get wordnik-python just:
$ easy_install wordnik
$ pip install wordnik
