Personally I don't think that Toga is a new engine at all. It seems that Toga is
in fact Fruit with a modified eval function. Even the 'Author' of Toga says that
Toga is mainly based on Fruit. Maybe Toga should be renamed to something like
Fruit-Toga or something similar in order to give credit to the original creator
of Fruit. Otherwise we face the same problem as with Linux. Many people don't
know about GNU, GPL or FSF but are proudly using Linux.
Do I create a new car by modifying the steering wheel on my car? Do I create a
new car by changing/adding some parts to the engine of my car?

To use another analogy, what if I'm leading a marathon and shortly before I
reach the finish line another runner joins the race and runs just the last 100
meters. As he is fresh and relaxed he will pass the finish line in front of me,
of course. But can we really compare this 2 runners?

While the 'author' of Toga certainly has some good understanding of chess
programming he mainly did some fine tuning on the evaluation function and
therefore he shouldn't get as much credit as Fabien. So a modified version of
Fruit should also get a name that shows that the engine is based on it IMO.
