Draco is very much a research project. It is not off-the-shelf software. If you intend to use it, you'll have to do some "development" work in writing new Draco procedures, primitives and implementations. We'll assist you as much as we can in this.
We're still very much interested in this project and welcome comments, suggestions, etc. Please send email to miller@stsci.edu. Even if you don't download Draco, your opinions and experiences with automating scientific data reduction and analysis are of interest.
