I recently saw https://lintian.debian.org/tags/binary-without-manpage.html and it shows around 14k manpages which are missing.
This means it's more than likely that some of the binary packages (not libraries) have missing manpages. How do I get a list of installed binary packages/applications (NOT libraries) which don't have manpages? I might know some and start contributing a bit towards that.
