PolyGlot can compile a pgn file into a binary PolyGlot book and furthermore
-it can merge two such binary books into a third one.
+it can merge two such binary books into a third one.
+.PP
+PolyGlot can also extract some useful information from PolyGlot books. The utility
+\&\*(L"dump\-book\*(R" dumps the \*(L"lines\*(R" in a book for a given color. By definition
+a line is a sequence of moves (from the starting position) in which
+the given color makes only book moves and the other color makes
+arbitrary moves (i.e. not necessarily book moves).
+.PP
+Since a PolyGlot book is built up from positions and not lines there
+may be (and there usually are) many positions in the book that are not
+on a \*(L"line\*(R" as defined in the previous paragraph. It is convenient
+to call such positions \*(L"isolated\*(R" positions. The utility \*(L"info\-book\*(R"
+counts such isolated positions.
+.PP
+Some of the isolated positions are provably unreachable and they
+could in principle be deleted from the book. For example if a book
+contains only the move \*(L"e4\*(R" in the starting position but also the
+position after \*(L"d4 d5\*(R" then this last position is provably unreachable
+since it requires white to make a non-book move when a book move is
+available. Such situations arise frequently from the priority rules
+in merging books.
+.PP
+Unfortunately not all isolated positions are provably unreachable and
+it is difficult to identify the latter. If invoked with \*(L"\-exact\*(R" the
+utility info-book will attempt to count the isolated positions which
+require a player to make a non-book move when a book move is available.
+Due to the possibility of transpositions this is not a fool proof method.
.Sh "Epd test mode"
.IX Subsection "Epd test mode"
In epd test mode, PolyGlot will search positions in an epd file and
words when a position occurs both in \*(L"in1\*(R" and \*(L"in2\*(R" only the
moves and weights from \*(L"in1\*(R" will be retained in \*(L"out\*(R".

\&\s-1NOTE:\s0 There can be spaces in option names or values. Do not use
quotes. Boolean values are written as \*(L"true\*(R" or \*(L"false\*(R".
.IX Item "ShowPonder (default: true)"
Show search information during engine pondering. Turning this off
might be better for interactive use in some interfaces.

+.IX Item "ScoreWhite (default: true)"
+Report score from white's point of view in xboard mode.
.IP "\fBKibitzMove\fR (default: false)" 4
.IX Item "KibitzMove (default: false)"
Whether to kibitz when playing a move.
How many seconds to wait before starting kibitzing. This has an
effect only if \*(L"KibitzPV\*(R" is selected, move kibitzes are always sent
regardless of the delay.
+.IP "\fBKibitzInterval\fR (default: 0)" 4
+.IX Item "KibitzInterval (default: 0)"
+This is another form of throttling. PolyGlot will usually wait this
+many seconds before doing the next kibitz.
.IP "\fB\s-1UCI\s0\fR (default: false)" 4
.IX Item "UCI (default: false)"
If true PolyGlot will not understand xboard commands.
.IX Subsection "Work arounds"
Work arounds are identical to options except that they should be used
only when necessary. Their purpose is to try to hide problems with
-various software (not just engines). The default value is always
-correct for bug-free software.

.PP
\&\s-1IMPORTANT:\s0 Any of these work arounds might be removed in future
versions of PolyGlot. You are strongly recommended to contact the
.IX Item "RepeatPV (default: true)"
When true, PolyGlot repeats the last pv string (which also contains
score,depth and time usage) it got from the engine. Some engines
-however do not send a new pv string just before sending the move and
-the now old pv string might confuse debugtools that parse the winboard
-debug files.
+however do not send a new pv string just before sending the move.
+In that case the output of PolyGlot would be inconsistent.
+When RepeatPV is false PolyGlot does not repeat the last pv string.
+Due to the way kibitzing is implemented, KibitzMove is disabled in that case.
+.IP "\fBWbWorkArounds\fR (default: true)" 4
+.IX Item "WbWorkArounds (default: true)"
+The intention of these options is to provide work arounds for
+xboard/winboard bugs should they arise. This one decapitalizes
+the word Draw in options that contain this word. Some versions of
+xboard/winboard contain a bug which causes such options to be
+interpreted as draw claims by the engine.
+.Sp
+Engines that send options with \*(L"Draw\*(R" in their name are Rybka and \s-1HIARCS\s0.
+.IP "\fBWbWorkArounds2\fR (default: false)" 4
+.IX Item "WbWorkArounds2 (default: false)"
+Old version of Winboard clear the engine output window at depth 1. With this
+work around \s-1PG\s0 will send info lines at depth >=2. This may or may not improve
+the display.
