API HAC has Argument, Argument_Count and Set_Exit_Status, and the result
can be piped.

However, I do not state HAC is production ready for GNATStudio... But
HAC is well written and easily hackable (I speak for Gautier ;)

You're right. That is the best way to handle it. But Emmanuel says that
the need for GNATStudio Python is mandatory anyway...

Freedom choice. I agree. But I guess Adacore ressources are limited and
this is like reinventing the wheel.

The free software way could be to fork GNATStudio, simplify it and fully
change the build process. Personnaly, I've either nor the time and the
skills to go this way...

The biggest complaint I had about GNATStudio was its instability. I
think that Adacore has made great progress now. It's now a pleasure to
work with.
