=item B<-var <variant>>
Forces uci2wb to announce to the GUI it supports (only) the specified variant.
-There is no standardized way for UxI engines to announce what they can play,
-so if these are not the standard variants implied by the protocol choice,
+Although a UCI_Variant option has been proposed as a way for UxI engines to announce what they can play,
+(and is supported by uci2wb), not many engines implement this.
+So if these are not the standard variants implied by the protocol choice,
(but, f.e. seirawan or 6x6+6_shogi) it has to be configured on the
uci2wb command line through this option.
