The file 'gnuchess.ini' allows setting configuration options, but it is
ignored if the \fB\-\-uci\fR option is used. See 'info gnuchess' for details
about the options. The program will look for 'gnuchess.ini' in
$XDG_CONFIG_HOME/gnuchess/ and $HOME/.config/gnuchess/ in that order,
and it will use the first one it finds, if any.
