Subject: Make debug output optional
X-Git-Tag: v2.0~49
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=5a5534346fd682f786f70694ab3e77d0ea653e3d;p=uci2wb.git

Make debug output optional

The debug output sent by UCI2WB to the GUI is made subject to an option
"UCI2WB debug output", which by default is set to false. A command-line
argument "debug" can set it to true from the beginning, so that you will
also be able to see the option handshaking.
