## Leo-Anki.js
/**
 * This bookmarklet makes it possible to transfer words from Leo Trainer to Anki.
 * It is configured for fr-de (French to German) translations, but can easily be
 * adapted to other languages.
 *
 * Prerequisites:
 * - a Leo account (http://www.leo.org/) with a few words saved in the trainer
 * - an Anki account (https://ankiweb.net/account/register)
 *
 * 1. Crunch the following code and add it to your bookmarks
 *    (see http://ted.mielczarek.org/code/mozilla/bookmarklet.html)
 * 2. Run the bookmarklet
 *    (you might have to run it twice, as the first run will lead you to the correct Leo page)
 * 3. Import the downloaded file in Anki using \t as field separator and allowing HTML in fields
