Magician is a commercial closed source product, and it is therefor a proprietary product ( -> GNU ).

It has a nice documentation. People who has switched from Magician to GL4Java,
because its Magician's proprietary approach, missed nothing, but the open source standard.

Well, I gave Magician no try, because of the license - thats it.

Ron Cemer, a GL4Java participant, just stated about the Magician approach,
that he is not willing to spend time and energy in bug finding for an closed and proprietary product.
So do I.
