              The file 'gnuchess.ini' allows setting config options if --uci
              is not used. See 'info gnuchess' for details. The file is looked
              for in three locations according to this precedence: current
              directory, the directory pointed to by environment variable
              GNUCHESS_PKGDATADIR, or the package data directory stated at
              configure time.
