I started working on something like this as I'm currently not aware
that this functionality already exists (someone correct me if I'm
wrong). My goal was to create a PDF with a list of packets and all
licenses. The design I chose was creating something text based directly
out of yocto (markdown) and using something like pandoc to convert that
to a PDF. I've abandoned the project for the moment as other things
became more important.
This is what I have so far, it currently depends on python tabulate and
generally has some rough edges. I called it "credits.bbclass" and just
used "inherit credits" in my image task. If someone wants to continue
working on it, go for it.
