Fafis is free software which can be used as an engine in interfaces
supporting the Winboard/UCI protocol, and I distribute it without any
warranty. Commercial use is prohibited. Only can be distributed if you
have my authorization in writing and as long as the content
of the ZIP-archives is unchanged. I take no responsibility for
any effect it has on your system, also as Fafis is free is your 
own choice use it or not. Any questions, suggestions,
optimized engine parameters or extended books are welcome.

Have fun!
