%description
Crafty is a chess program written by Bob Hyatt <hyatt at cis.uab.edu>.
It is a direct descendent of Cray Blitz, the World Computer Champion
from 1983 to 1989.

It comes with a text interface like gnuchess do. If you want a graphical
interface, you can install GUI chessboards such as xboard and eboard.

Crafty is based on the classic BITMAP approach to representing the chess
board, but uses a unique methodology called "rotated bitmaps" to
significantly improve the performance of the chess engine.
