Re: GtkAda for professional GUI-Application ?

[Frank Piron <frank.piron@konad.de>]

Thanks a lot for your complete analysis.
Alternative 3 is what I'd like to do, but our

I will take a serious look at Yudit and at rapid.
Alternative 2 may be an option for the future and
we plan to start a non-critical pilot.

Greetings from Germany, Frank
