You can remove the ".git" suffix.

This dance is not necessary. You can simply use
`emacs-substitute-variables', change the value, and keep the defcustom.
A defconst is not a constant in Elisp anyway.

You can remove the final full stop.

It may be clearer to also mention "Potassco" so as to understand better
the PASP acronym.

I suggest "Answer Set Programs", since this seems to be a very specific thing.

I didn't build it, but LGTM.
