Foreign Language Education Software For Linux?

torinth asks: "Once upon a time, long, long, ago, I took some French classes in high school. I had to drop them, eventually, to provide more time for silly engineering courses, but now I want to get to back to learning the language a bit. Obviously, the best approach is to move up to Montreal or Paris for a bit and learn through immersion, but I really wouldn't mind getting a refresher first. There's a lot of Windows software for learning languages, but I just nuked my Windows partition, so now I'm wondering: Do any language educational programs exist for Linux?"
