It will be hard to automate the translation from existing spec to a template form, but I can eventually look at it. Adding ucrt64 packages is still optional, and can be done manually anyway. Templating is optional too, obviously. Also I don't know what are Daniel Berrange plans to have native and cross packages built from the same spec. We might end up with a very different solution then. -- Marc-André Lureau
