This sounds great! Hey, while you're at it, I would love a dia to CORBA IDL transform... Is that on your agenda?
If not I may try to implement one myself. I want to preserve packages
and translate them to CORBA modules. Would it be tricky to work out
whether a class/interface sits on top of a package, so that it generates
the code with a module { ... } construct around it?
Cheers,
Dominic Gamble.
