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".

-Lines starting with \*(L"#\*(R" are ignored.
+The characters \*(L"#\*(R" and \*(L";\*(R" serve as comment characters.
.PP
\&\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.
+.IP "\fBScoreWhite\fR (default: true)" 4
+.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 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.
