If you are the author of a commercial chess engine,
or, as "beta tester", related to an author of a
commercial chess engine, and want to use Toga based on
Fruit in automated or non-automated tests in order to
improve your own engine, then it would be very nice if
you send me one copy of your engine (current release)
for my own private testing purposes.

bitbases by Daniel Shawul (Scorpio)
A very big thank to Daniel for sharing his great
endgame bitbases and his dll.
EGBBs ----- Toga uses the Scorpio endgame bitbases
upto 5 pieces.
Installation ------------ First You have to download
the 5men bitbases from Leo Dijksman's WBEC site http://www.wbec-ridderkerk.nl
. The egbbs are 340mb in size. Then put them anywhere in
your computer. The default path is c:\egbb\ but you can
change this in the uci options. The egbbdll.dll must be
in the same folder as the bitbase files.
Thanks Fabien Letouzey for the great source code of
the program Fruit 2.1.
Special thanks to Dieter Eberle, Karl-Heinz Söntges,
Shaun Brewer for testing Beta Versions. A big thank to
Dieter Eberle for his setting. Orlando Mouchel for
bugfixes and new ideas. Raimund Heid for his new ideas.
Wilhelm Hudetz for the Logo.
Without their help i wouldn´t be able to increase the
playing strenght, compared to Fruit 2.1, by about 100
Elo.
