I agree with RMS (<E1odDGZ-0005aw-79@fencepost.gnu.org>) that it might
be nice to have a more indicative name, or at least something that
includes "Prolog". Mor eso because "sweep" makes me think of something
that cleans.

The main advantage I see would be that anyone who uses `prolog-mode'
could inherit their customisations when using sweep. And it shouldn't
be an issue if sweep-mode overrides most of what `prolog-mode' defines.

Is the error self-explanatory, in the sense that a user would be able to
understand that SWI Prolog is outdated? There are some packages that
build software themselves (e.g. pdf-tools), but I don't think that issue
has ever been solved in a clean and robust way.
