prolog-el 1.25-2 (arm64 binary) in ubuntu yakkety

 This is a replacement for the standard emacs prolog mode. It comes
 with all the features you would expect, including syntax
 highlighting, auto indent, and full interaction with an inferior
 Prolog process.
 .
 This mode supports in principle any Prolog system, though it is
 primarily maintained for SWI Prolog. It also has some special tweaks
 for GNU Prolog and SICStus Prolog, and explicitly supports Prolog's
 close relatives Eclipse and Mercury.
