@cindex recentEngines, option
Analyze mode by holding the Shift key down while entering a move.
When it is off, the Shift key will be ignored.
Default: False.
+@item -appendPV true|false
+@cindex appendPV, option
+When this option is on, right-clicking a PV in the Engine Output window
+will play the first move of that PV in Analyze mode,
+or as many moves as you walk through by moving the mouse.
+Default: False.
@item -absoluteAnalysisScores true|false
@cindex absoluteAnalysisScores, option
When true, scores on the Engine Output window during analysis
When true, scores will always be printed from the white point-of-view,
rather than the side-to-move point-of-view.
Default: False.
+@item -memoHeaders true|false
+@cindex memoHeaders, option
+When true, column headers will be displayed in the Engine Output window
+for the depth, score, time and nodes data.
+Right-clicking on these headers will hide or show the corresponding data.
+(Not intended for dynamic use, as already printed data of the current search
+will not be affected!)
+Defaul: False.

@node Adjudication Options
If this option is true, XBoard acts as a passive chessboard; it
does not start a chess engine at all. Turning on this option
also turns off clockMode. Default: false.
+@item -viewer
+@itemx -viewerOptions string
+@cindex viewer, option
+@cindex viewerOptions, option
+Presence of the volatile option @code{viewer} on the command line
+will cause the value of the persistent option @code{viewerOptions}
+as stored in the settings file to be appended to the command line.
+The @code{view} option will be used by desktop associations with
+game or position file types, so that @code{viewerOptions} can be
+used to configure the exact mode XBoard will start in when it
+should act on such a file (e.g. in -ncp mode, or analyzing
+with your favorite engine). The options are also automatically
+appended when Board is invoked with a single argument not being
+an option name, which is then assumed to be the name of a
+@code{loadGameFile} or (when the name ends in .fen) a
+@code{loadPositionFile}.
+Default: "-ncp -engineOutputUp false -saveSettingsOnExit false".
+@item -tourneyOptions string
+@cindex tourneyOptions, option
+When XBoard is invoked with a single argument that is a file
+with .trn extension, it will assume this argument to be the value
+of a @code{tourneyFile} option,
+and apped the value of the persistent option @code{tourneyOptions}
+as stored in the settings file to the command line.
+Thus the value of @code{tourneyOptions} can be
+used to configure XBoard to automatically start running a
+tournament when it should act on such a file.
+Default: "-ncp -mm -saveSettingsOnExit false".
@item -mode or -initialMode modename
@cindex mode, option
@cindex initalMode, option
knightmate King moves as Knight, and vice versa
super Superchess (shuffle variant with 4 exo-pieces)
makruk Thai Chess (shatranj-like, P promotes on 6th rank)
+asean ASEAN Chess (a modernized version of Makruk)
spartan Spartan Chess (black has unorthodox pieces)
fairy A catchall variant in which all piece types
known to XBoard can participate (8x8)
@itemx -delayAfterQuit number
@cindex delayBeforeQuit, option
@cindex delayAfterQuit, option
-These options specify how long XBoard has to wait before sending a termination signal to rogue engine processes, that do not want to react to the 'quit' command. The second one determines the pause after killing the engine, to make sure it dies.
+These options order pauses before and after sending the "quit" command to an engine that must be terminated.
+The pause between quit and the previous command is specified in milliseconds.
+The pause after quit is used to schedule a kill signal to be sent to the engine process after the
+number of specified seconds plus one.
+This signal is a different one as the terminiation signal described in the protocol specs
+which engines can suppress or ignore, and which is sent directly after the "quit" command.
+Setting @code{delayAfterQuit} to -1 will suppress sending of the kill signal.
+Default: 0
@item -searchMode n
@cindex searchMode, option
The integer n encodes the mode for the @samp{find position} function.
* Fairy-Max:: The Fairy-Max chess engine.
* HoiChess:: The HoiChess chess engine.
* Crafty:: The Crafty chess engine.

-
-The ``zic2xpm'' program is used to import chess sets from the ZIICS(*)
-program into XBoard. ``zic2xpm'' is part of the XBoard distribution.
-ZIICS is available from:
-
-ftp://ftp.freechess.org/pub/chess/DOS/ziics131.exe
-
-To import ZIICS pieces, do this:
-@table @asis
-@item 1. Unzip ziics131.exe into a directory:
-
-@example
-unzip -L ziics131.exe -d ~/ziics
-@end example
-@item 2. Use zic2xpm to convert a set of pieces to XBoard format.
-
-For example, let's say you want to use the
-FRITZ4 set. These files are named ``fritz4.*'' in the ZIICS distribution.
-
-@example
-mkdir ~/fritz4
-cd ~/fritz4
-zic2xpm ~/ziics/fritz4.*
-@end example
-@item 3. Give XBoard the ``-pixmap'' option when starting up, e.g.:
-
-@example
-xboard -pixmap ~/fritz4
-@end example
-@end table
