I must say that Sun Bear is a bit odd looking, as if it has been open sourced one too many times, with multiple engineers adding the very best features without checking whether they work together or not... :-)
And here's a full description of Sun Bear. It eats fruit and lives in trees. Hmmm. Doesn't really fulfil my expectations of the concept "bear". Maybe this is post-modern bear, declawed and vegetarian.
Cheers!
