It would be nice if it can also warn users that a given combination is incompatible. E.g. the Apache License version 2 and the GPL version 1/2 are not compatible. The current comparison suggests that they are.
This site was discussed 3 months ago: <a href="http://news.ycombinator.com/item?id=4193152" rel="nofollow">http://news.ycombinator.com/item?id=4193152</a><p>This "combine" feature seems new though.<p>I don't understand how it works.
