I agree with Hartmut. I also found this confusing. I've attached a patch to try clarifying it. What do you think? If the Guix manual had told me that the repository's root directory will basically be added to the Guile load path, I would have understood the expected file structure immediately. The Guile manual clearly describes the requirements for making modules available via the load path. Maybe the existing text was clear enough for some. I read it but still wasn't sure exactly how Guix expected me to lay out my channel's files. -- Chris
