Will users of the command line scripts (e.g. rdfpipe, csv2rdf, etc.) care
whether it's Python 2 or Python 3? For most such projects, it doesn't matter,
in which case, I would say that the /usr/bin scripts should be the Python 3
version, all else being equal. In which case, you can probably just discard
the Python 2 shebanged versions.
If it still makes sense to have both Python 2 and Python 3 versions of the
libraries, then you might indeed want to have a separate binary package for
the /usr/bin scripts, but they'd only contain the Python 3 version. Having
the -tools package (or -bin or -cli or -scripts or whatever ;) just contain
symlinks from /usr/bin into /usr/share/python3-rdflib/tools might make sense.
