Qtopia with qt embedded??

[Yayati.Ekbote]

I have to make an application in qt embedded. So i downloaded qt libraries 4.6.2 for embedded linux. On some googling i found that Qtopia is needed above qt embedded. On trolltech's website it is given that qtopia resides over qt-extended. Whats the difference between qt embedded and qt extended??? What should i do to make use of qtopia to make an application for embedded device?

The product Qtopia is discontinued. Who says that Qtopia is required and for solving which particular problem?
