Thank you for considering the issues and asking for advice.

This seems to be more common now that command-line invocation is
becoming even more discouraged. When the upstream documentation
recommends ‘python3 -m foo.bar’ as the primary means of invoking the
command line functionality, that really blurs the line between
command-line application versus library.

There is a compounding tendency to disparage ‘python3 ./foo/bar.py’,
which is subject to weird hacks and incomplete workarounds like
<URL:https://www.python.org/dev/peps/pep-0366/>. I wish this trend could
be effectively reversed, because IMO this is a serious impediment to
considering Python a good choice for command-line scripting. But this is
all a digression, my apologies.

I don't understand this statement. If it is *only* useful as a library,
why install the command-line entry point?

Why not install the command by using the configuration files for
‘dh_install(1)’; that is, specify in ‘debian/slugify.install’ the files
to install.
