I agree that at this point in time we have to move beyond descriptions and start looking at source and detailed functionality, because that is where the differences between Cargo and Metacello will manifest themselves ... they are both package managers after all:) Dale

So to summarise the great thing about NB is that it does assembly code with pharo syntax, the bad thing about NB is that it does assembly code with pharo syntax. Of course there are not that many people around to be sane enough to write assembly , so of course it will be removed at some point.
