I've been looking at this package, you can see its review status at https://dfsg-new-queue.debian.org/reviews/python-notobuilder
This package depends on at least 3 package not currently in Debian: python3-chevron, python3-diffenator2, python3-gftools-, python3-ufomerge. Why is that? Are those dependencies an oversight or intentional? Note that python3-gftools- looks suspicious, can you please clarify why that is? I note that the debian/ packaging is under a different license than the actual package. Usually the packaging follows the usptream license for simpliciy. What's the reason for diverging here? Thanks, -rt
