   Dogelog Player is a Prolog system that is written   
   in 100% Prolog. Formerly Jekejeke Prolog was a   
   Prolog system that was written in 100% Java. We   
   created a new version of Jekejeke Prolog that   
   has 50% Prolog from Dogelog Player and is   
   still multi-threaded.   
      
   We trashed everything beyond the core of Jekejeke   
   Prolog and adopted the Dogelog Player libraries   
   and top-level, even library(markup) works! The   
   new Jekejeke Prolog is significantly slower than   
   Dogelog Player, almost a factor two. But it can still   
   serve for some cherry picking.
