Offline chess engine with FEN process

Hi,

I am working on a chess GUI as a hobby project and I am looking for a (preferably lightweight) command line chess engine which accepts FEN position as an input an preferably outputs the recommended move in algebratic notation.

(worst case I can live with algebratic input, but I would really prefer FEN)

Please help me out.
Thanks,
Istvan

Try crafty chess engine. It can output it's analysis in SAN and it can take a FEN input.

Arasan can also do it too I think.

Why don't you use Stockfish?
(site: http://stockfishchess.org/download/)
(a bit of commands: http://support.stockfishchess.org/kb/advanced-topics/engine-parameters

Stockfish does not output in SAN, but uses a kind of long algebraic notation from UCI protocol.
