--- Comment #3 from Raphael Groner projects.rg@smart.ms ---
From the homepage:
A moderately strong chess engine is included: Dreamer. However, should this engine be too weak for you, then you can use any other XBoard-compatible chess engine, including the popular Crafty and GNU Chess.
Cause of that I am thinking about moving dreamer binary and manpage into separate subpackage(s). An user could use dreamchess with GNU chess only.
