The protocols for which it can mediate are UCI
(both the official standard, as well as the 'Cyclone dialect' that is commonly used
-by Chinese-Chess engines),
+by Chinese-Chess engines, and the 'Arena960 dialect' used by pre-standard Chess960 engines),
USI ('Universal Shogi Interface', used by some Shogi engines)
and UCCI ('Universal Chinese-Chess Interface').
When set to UCI, it automatically uses Cyclone dialect when playing xiangqi games.

-=item B<-c -s -x>
+=item B<-c -s -x -f>
The flag arguments B<-c> (default), B<-s> or B<-x> set uci2wb to use UCI, USI or UCCI, respectively.
If there is more than one character in the flag argument,
all characters but the first are ignored.
This can be used by passing uci2wb the full variant name ('shogi' or 'xiangqi') as a flag,
to make it automatically choose the appropriate protocol (USI or UCCI).
+Other values also select UCI, but the value B<-f> in addition implies uci2wb should announce
+it supports Chess960 even for UCI engines that don't have the standard UCI_Chess960 option,
+and in that case causes castlings to be sent to them as O-O or O-O-O
+instead of the standard KxR notation.

=item B<debug>
Some critical commands it sends to the engine
(such as the 'position-moves' and 'go' commands)
will be reported as well.
-
+This option can also be switched interactively,
+through the 'UCI2WB debug output' checkbox option appearing
+as additional engine option.
=item B<directory>
If a directory is specified, the engine is started
with that directory set as current directory.
+=item N<byoyomi work-arounds>
+
+Byoyomi is a mode of time control in USI not supported by CECP.
+Engines can be forced to run in this mode by letting the GUI use
+incremental or sudden-death TC,
+and ticking the interactive 'Floating Byoyomi' checkbox option
+that uci2wb pools with the engine options.
+An accompanying option 'Byoyomi (sec)' allows you to force a fixed
+value >= 0 for the byoyomi to be sent to the engine
+when 'Floating Byoyomi' is off.
