[LRUG] Quiz/questionnaire libraries?

[James Mead]

Can anyone recommend any good Ruby open-source libraries for quizzes/questionnaires? 

I haven't looked at it in detail, but the "Survey" Rails Engine [1] looks close to what I'm after. Has anyone used it?

I'd be particularly interested in anything that offers compatibility with any LMS/educational/e-Learning standards e.g. allowing importing of quizzes from other systems.

Cheers, James.
