    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 Sntges, Shaun Brewer for testing Beta Versions.
A big thank to Dieter Eberle for his setting.
