I understand the issue. I definitely HAVE TO learn Guile. During the internship -and now- I am able to understand what the code is doing and change it a little bit, or set the configuration of the distro for instance, but I don't know to write from scratch :/ While writing this I am opening a tutorial :) Regards :) Laura
