The front-end is. The back end (GCC) is in C, I believe. Janus/Ada is all 
Ada except for a snippet of assembler in the runtime.

Why do you say that? It's something I've thought about; I'd certainly do it 
if I decided to stop selling it. I don't think there is any business reason 
that it couldn't be open-sourced at this point (that wouldn't have been true 
10 years ago).
