Wrong, Keith. This isn't the sort of claim you want to make while attempting to become a respected writer on software topics, although you are in good company with many technical journalists. With the exception of pure-BSD purists (who reject the patent clauses) AL can be mixed with any code to come out with the more restrictive of the licenses. AL + BSD == AL AL + MPL == MPL AL + GPL == GPL The following are not possible; AL + BSD != BSD AL + MPL != MPL AL + GPL != AL So the input AL code can be combined as a donor to any effort and result in an appropriate license to the finished effort. The converse cannot be said of GPL, which explicitly prohibits additional terms or conditions on the resulting license. GPL is type AB+, as it can not produce other outcome. Perhaps your ignorance comes from medical science, though? You supposedly learned this in 6th grade, but I wouldn't brag about your report card. --------------------------------------------------------------------- To unsubscribe, e-mail: general-unsubscr...@incubator.apache.org For additional commands, e-mail: general-h...@incubator.apache.org
