    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\ (Windows) or /usr/share/egbb (Unix/Linux) but you can change this in the uci options. 
       The egbbdll.dll (Windows) or egbbso.so (Linux/Unix) 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 Sntges, Shaun Brewer for testing Beta Versions.
A big thank to Dieter Eberle for his setting.
Orlando Mouchel for bugfixes and new ideas.
Wilhelm Hudetz for the Logo.

Without their help i wouldnt be able to increase the playing strenght, compared to Fruit 2.1, by about 100 Elo.
