=head1 OPTIONS
-When invoked without options or with a config file as argument PolyGlot
-acts as an adapter. The config file format is documented below. The
-default config file is "polyglot.ini".
+When PolyGlot is invoked as an adapter of in epd-test mode it gets its
+options from a config file and then from the command line. The
+default config file is "polyglot.ini" but an alternative one may be
+optionally included as first argument. The config file format is
+described below.
-When invoked as
+The following engine options may be specified on the command line.

+Do not use a config file, even if one was specified on the command line.

+
+The argument is a string of the form <name>=<value>. This option will
+set the Polyglot option <name> to <value>.

+The argument is a string of the form <name>=<value>. This option will

-PolyGlot simply starts "engine" and acts as an adapter. No config file
-is used and thus it is expected that all properties will be set by the
-GUI.

The characters "#" and ";" serve as comment characters.
-NOTE: There can be spaces in option names or values. Do not use
-quotes. Boolean values are written as "true" or "false".
+Initial and final white space is stripped from option names and
+values. If you need to use characters which have a special meaning to
+PolyGlot (these are ';#[]=\') you should quote them by preceding them
+with '\'. "Quoting" other characters in this way has no effect. In
+particular the use of '\' as a path separator in windows should
+normally not affected.

command-line arguments. Path searching is used and the current

+to wordexp so that shell quoting rules and expansions are applied.
+On Windows the EngineCommand is simply passed to CreateProcess which
+does its own shell like processing.

+=item B<SettingsDir> (default: $HOME/.polyglot on Linux; ".\_PG" on Windows)
+
+The directory where ini files are stored for engines that are started with
+-noini. Such ini files may be created by pushing the "Save" button in the
+Engine settings dialog in WB/XB 4.4.0 and higher. As a special exception
+(for WB/XB 4.4.0 compatibility) this directory is also used in case
+PolyGlot is started with config files named "polyglot_1st.ini" or
+"polyglot_2nd.ini".
=item B<Log> (default: false)
If true PolyGlot will not understand xboard commands.
-=item B<Chess960> (default: false)
-
-Play Chess960 (also called Fischer Random Chess or FRC),

=item B<MateScore> (default: 10000)
-Mate score reported to GUI when in xboard mode.
+Mate score reported to GUI when in xboard mode.
=item B<Book> (default: false)
=item B<BookLearn> (default: false)
-Record learning information in the opening book. Naturally this requires
-the opening book to be writable.
+This is a noop.
+
+=item B<BookDepth> (default: 256)
+
+Stop using the book after this number of moves.
+
+=item B<BookTreshold> (default: 5)
+
+Do not play moves with a weight (probability) lower than this (in per mil).
=item B<UseNice> (default: false)
This a bit vector in which each bit represents the processors that a
process is allowed to run on. This option works only on Windows.
+=item B<STFudge> (default: 20)
+
+PolyGlot will translate "st x" as "go movetime 1000*x-STFudge".
+The rationale is that in the UCI specification the argument of movetime
+is defined as the exact search time whereas the argument of the
+st command is only an upperbound.
+
+=item B<OnlyWbOptions> (default: true)
+
+If true then PolyGlot restricts the options it sends to those that
+are potentially useful for WinBoard.

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.

+An explicit command line for using the UCI engine "fruit" with logging enabled (this works also with older versions of xboard).
