Good news. However, I have some questions:

1. Upon issuing 'uci', this is what I see:

uci
id name ShenYu 2.0.0
id author Aaron Li
option name Hash type spin default 64 min 0 max 65536
option name hash type spin default 64 min 0 max 65536
option name Clear Hash type button
option name clear hash type button
uciok

Why is everything duplicated in lowercase?

2. Even if I set hash to 256 MB it occupies only 68 MB memory.

Hi Gabor -
1. That's something I forgot to remove. Both lowercase and uppercase work.
2. This looks like a uci parsing bug. My guess is that I forgot that setoption commands also require "value." (looks like this is exactly what happened.)

I'm putting out a patch that fixes these issues.

Fine, thanks. Now only the version number is wrong in the UCI id.

Very good. I can rename the exe myself if I wish so.
