+ GNU GENERAL PUBLIC LICENSE\r
+ Version 2, June 1991\r
+\r
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.\r
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA\r
+ Everyone is permitted to copy and distribute verbatim copies\r
+ of this license document, but changing it is not allowed.\r
+\r
+ Preamble\r
+\r
+ The licenses for most software are designed to take away your\r
+freedom to share and change it. By contrast, the GNU General Public\r
+License is intended to guarantee your freedom to share and change free\r
+software--to make sure the software is free for all its users. This\r
+General Public License applies to most of the Free Software\r
+Foundation's software and to any other program whose authors commit to\r
+using it. (Some other Free Software Foundation software is covered by\r
+the GNU Library General Public License instead.) You can apply it to\r
+your programs, too.\r
+\r
+ When we speak of free software, we are referring to freedom, not\r
+price. Our General Public Licenses are designed to make sure that you\r
+have the freedom to distribute copies of free software (and charge for\r
+this service if you wish), that you receive source code or can get it\r
+if you want it, that you can change the software or use pieces of it\r
+in new free programs; and that you know you can do these things.\r
+\r
+ To protect your rights, we need to make restrictions that forbid\r
+anyone to deny you these rights or to ask you to surrender the rights.\r
+These restrictions translate to certain responsibilities for you if you\r
+distribute copies of the software, or if you modify it.\r
+\r
+ For example, if you distribute copies of such a program, whether\r
+gratis or for a fee, you must give the recipients all the rights that\r
+you have. You must make sure that they, too, receive or can get the\r
+source code. And you must show them these terms so they know their\r
+rights.\r
+\r
+ We protect your rights with two steps: (1) copyright the software, and\r
+(2) offer you this license which gives you legal permission to copy,\r
+distribute and/or modify the software.\r
+\r
+ Also, for each author's protection and ours, we want to make certain\r
+that everyone understands that there is no warranty for this free\r
+software. If the software is modified by someone else and passed on, we\r
+want its recipients to know that what they have is not the original, so\r
+that any problems introduced by others will not reflect on the original\r
+authors' reputations.\r
+\r
+ Finally, any free program is threatened constantly by software\r
+patents. We wish to avoid the danger that redistributors of a free\r
+program will individually obtain patent licenses, in effect making the\r
+program proprietary. To prevent this, we have made it clear that any\r
+patent must be licensed for everyone's free use or not licensed at all.\r
+\r
+ The precise terms and conditions for copying, distribution and\r
+modification follow.\r
+\f\r
+ GNU GENERAL PUBLIC LICENSE\r
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
+\r
+ 0. This License applies to any program or other work which contains\r
+a notice placed by the copyright holder saying it may be distributed\r
+under the terms of this General Public License. The "Program", below,\r
+refers to any such program or work, and a "work based on the Program"\r
+means either the Program or any derivative work under copyright law:\r
+that is to say, a work containing the Program or a portion of it,\r
+either verbatim or with modifications and/or translated into another\r
+language. (Hereinafter, translation is included without limitation in\r
+the term "modification".) Each licensee is addressed as "you".\r
+\r
+Activities other than copying, distribution and modification are not\r
+covered by this License; they are outside its scope. The act of\r
+running the Program is not restricted, and the output from the Program\r
+is covered only if its contents constitute a work based on the\r
+Program (independent of having been made by running the Program).\r
+Whether that is true depends on what the Program does.\r
+\r
+ 1. You may copy and distribute verbatim copies of the Program's\r
+source code as you receive it, in any medium, provided that you\r
+conspicuously and appropriately publish on each copy an appropriate\r
+copyright notice and disclaimer of warranty; keep intact all the\r
+notices that refer to this License and to the absence of any warranty;\r
+and give any other recipients of the Program a copy of this License\r
+along with the Program.\r
+\r
+You may charge a fee for the physical act of transferring a copy, and\r
+you may at your option offer warranty protection in exchange for a fee.\r
+\r
+ 2. You may modify your copy or copies of the Program or any portion\r
+of it, thus forming a work based on the Program, and copy and\r
+distribute such modifications or work under the terms of Section 1\r
+above, provided that you also meet all of these conditions:\r
+\r
+ a) You must cause the modified files to carry prominent notices\r
+ stating that you changed the files and the date of any change.\r
+\r
+ b) You must cause any work that you distribute or publish, that in\r
+ whole or in part contains or is derived from the Program or any\r
+ part thereof, to be licensed as a whole at no charge to all third\r
+ parties under the terms of this License.\r
+\r
+ c) If the modified program normally reads commands interactively\r
+ when run, you must cause it, when started running for such\r
+ interactive use in the most ordinary way, to print or display an\r
+ announcement including an appropriate copyright notice and a\r
+ notice that there is no warranty (or else, saying that you provide\r
+ a warranty) and that users may redistribute the program under\r
+ these conditions, and telling the user how to view a copy of this\r
+ License. (Exception: if the Program itself is interactive but\r
+ does not normally print such an announcement, your work based on\r
+ the Program is not required to print an announcement.)\r
+\f\r
+These requirements apply to the modified work as a whole. If\r
+identifiable sections of that work are not derived from the Program,\r
+and can be reasonably considered independent and separate works in\r
+themselves, then this License, and its terms, do not apply to those\r
+sections when you distribute them as separate works. But when you\r
+distribute the same sections as part of a whole which is a work based\r
+on the Program, the distribution of the whole must be on the terms of\r
+this License, whose permissions for other licensees extend to the\r
+entire whole, and thus to each and every part regardless of who wrote it.\r
+\r
+Thus, it is not the intent of this section to claim rights or contest\r
+your rights to work written entirely by you; rather, the intent is to\r
+exercise the right to control the distribution of derivative or\r
+collective works based on the Program.\r
+\r
+In addition, mere aggregation of another work not based on the Program\r
+with the Program (or with a work based on the Program) on a volume of\r
+a storage or distribution medium does not bring the other work under\r
+the scope of this License.\r
+\r
+ 3. You may copy and distribute the Program (or a work based on it,\r
+under Section 2) in object code or executable form under the terms of\r
+Sections 1 and 2 above provided that you also do one of the following:\r
+\r
+ a) Accompany it with the complete corresponding machine-readable\r
+ source code, which must be distributed under the terms of Sections\r
+ 1 and 2 above on a medium customarily used for software interchange; or,\r
+\r
+ b) Accompany it with a written offer, valid for at least three\r
+ years, to give any third party, for a charge no more than your\r
+ cost of physically performing source distribution, a complete\r
+ machine-readable copy of the corresponding source code, to be\r
+ distributed under the terms of Sections 1 and 2 above on a medium\r
+ customarily used for software interchange; or,\r
+\r
+ c) Accompany it with the information you received as to the offer\r
+ to distribute corresponding source code. (This alternative is\r
+ allowed only for noncommercial distribution and only if you\r
+ received the program in object code or executable form with such\r
+ an offer, in accord with Subsection b above.)\r
+\r
+The source code for a work means the preferred form of the work for\r
+making modifications to it. For an executable work, complete source\r
+code means all the source code for all modules it contains, plus any\r
+associated interface definition files, plus the scripts used to\r
+control compilation and installation of the executable. However, as a\r
+special exception, the source code distributed need not include\r
+anything that is normally distributed (in either source or binary\r
+form) with the major components (compiler, kernel, and so on) of the\r
+operating system on which the executable runs, unless that component\r
+itself accompanies the executable.\r
+\r
+If distribution of executable or object code is made by offering\r
+access to copy from a designated place, then offering equivalent\r
+access to copy the source code from the same place counts as\r
+distribution of the source code, even though third parties are not\r
+compelled to copy the source along with the object code.\r
+\f\r
+ 4. You may not copy, modify, sublicense, or distribute the Program\r
+except as expressly provided under this License. Any attempt\r
+otherwise to copy, modify, sublicense or distribute the Program is\r
+void, and will automatically terminate your rights under this License.\r
+However, parties who have received copies, or rights, from you under\r
+this License will not have their licenses terminated so long as such\r
+parties remain in full compliance.\r
+\r
+ 5. You are not required to accept this License, since you have not\r
+signed it. However, nothing else grants you permission to modify or\r
+distribute the Program or its derivative works. These actions are\r
+prohibited by law if you do not accept this License. Therefore, by\r
+modifying or distributing the Program (or any work based on the\r
+Program), you indicate your acceptance of this License to do so, and\r
+all its terms and conditions for copying, distributing or modifying\r
+the Program or works based on it.\r
+\r
+ 6. Each time you redistribute the Program (or any work based on the\r
+Program), the recipient automatically receives a license from the\r
+original licensor to copy, distribute or modify the Program subject to\r
+these terms and conditions. You may not impose any further\r
+restrictions on the recipients' exercise of the rights granted herein.\r
+You are not responsible for enforcing compliance by third parties to\r
+this License.\r
+\r
+ 7. If, as a consequence of a court judgment or allegation of patent\r
+infringement or for any other reason (not limited to patent issues),\r
+conditions are imposed on you (whether by court order, agreement or\r
+otherwise) that contradict the conditions of this License, they do not\r
+excuse you from the conditions of this License. If you cannot\r
+distribute so as to satisfy simultaneously your obligations under this\r
+License and any other pertinent obligations, then as a consequence you\r
+may not distribute the Program at all. For example, if a patent\r
+license would not permit royalty-free redistribution of the Program by\r
+all those who receive copies directly or indirectly through you, then\r
+the only way you could satisfy both it and this License would be to\r
+refrain entirely from distribution of the Program.\r
+\r
+If any portion of this section is held invalid or unenforceable under\r
+any particular circumstance, the balance of the section is intended to\r
+apply and the section as a whole is intended to apply in other\r
+circumstances.\r
+\r
+It is not the purpose of this section to induce you to infringe any\r
+patents or other property right claims or to contest validity of any\r
+such claims; this section has the sole purpose of protecting the\r
+integrity of the free software distribution system, which is\r
+implemented by public license practices. Many people have made\r
+generous contributions to the wide range of software distributed\r
+through that system in reliance on consistent application of that\r
+system; it is up to the author/donor to decide if he or she is willing\r
+to distribute software through any other system and a licensee cannot\r
+impose that choice.\r
+\r
+This section is intended to make thoroughly clear what is believed to\r
+be a consequence of the rest of this License.\r
+\f\r
+ 8. If the distribution and/or use of the Program is restricted in\r
+certain countries either by patents or by copyrighted interfaces, the\r
+original copyright holder who places the Program under this License\r
+may add an explicit geographical distribution limitation excluding\r
+those countries, so that distribution is permitted only in or among\r
+countries not thus excluded. In such case, this License incorporates\r
+the limitation as if written in the body of this License.\r
+\r
+ 9. The Free Software Foundation may publish revised and/or new versions\r
+of the General Public License from time to time. Such new versions will\r
+be similar in spirit to the present version, but may differ in detail to\r
+address new problems or concerns.\r
+\r
+Each version is given a distinguishing version number. If the Program\r
+specifies a version number of this License which applies to it and "any\r
+later version", you have the option of following the terms and conditions\r
+either of that version or of any later version published by the Free\r
+Software Foundation. If the Program does not specify a version number of\r
+this License, you may choose any version ever published by the Free Software\r
+Foundation.\r
+\r
+ 10. If you wish to incorporate parts of the Program into other free\r
+programs whose distribution conditions are different, write to the author\r
+to ask for permission. For software which is copyrighted by the Free\r
+Software Foundation, write to the Free Software Foundation; we sometimes\r
+make exceptions for this. Our decision will be guided by the two goals\r
+of preserving the free status of all derivatives of our free software and\r
+of promoting the sharing and reuse of software generally.\r
+\r
+ NO WARRANTY\r
+\r
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\r
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\r
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\r
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\r
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\r
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\r
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\r
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\r
+REPAIR OR CORRECTION.\r
+\r
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\r
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\r
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\r
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\r
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\r
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\r
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\r
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\r
+POSSIBILITY OF SUCH DAMAGES.\r
+\r
+ END OF TERMS AND CONDITIONS\r
+\f\r
+ How to Apply These Terms to Your New Programs\r
+\r
+ If you develop a new program, and you want it to be of the greatest\r
+possible use to the public, the best way to achieve this is to make it\r
+free software which everyone can redistribute and change under these terms.\r
+\r
+ To do so, attach the following notices to the program. It is safest\r
+to attach them to the start of each source file to most effectively\r
+convey the exclusion of warranty; and each file should have at least\r
+the "copyright" line and a pointer to where the full notice is found.\r
+\r
+ <one line to give the program's name and a brief idea of what it does.>\r
+ Copyright (C) <year> <name of author>\r
+\r
+ This program is free software; you can redistribute it and/or modify\r
+ it under the terms of the GNU General Public License as published by\r
+ the Free Software Foundation; either version 2 of the License, or\r
+ (at your option) any later version.\r
+\r
+ This program is distributed in the hope that it will be useful,\r
+ but WITHOUT ANY WARRANTY; without even the implied warranty of\r
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\r
+ GNU General Public License for more details.\r
+\r
+ You should have received a copy of the GNU General Public License\r
+ along with this program; if not, write to the Free Software\r
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA\r
+\r
+\r
+Also add information on how to contact you by electronic and paper mail.\r
+\r
+If the program is interactive, make it output a short notice like this\r
+when it starts in an interactive mode:\r
+\r
+ Gnomovision version 69, Copyright (C) year name of author\r
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\r
+ This is free software, and you are welcome to redistribute it\r
+ under certain conditions; type `show c' for details.\r
+\r
+The hypothetical commands `show w' and `show c' should show the appropriate\r
+parts of the General Public License. Of course, the commands you use may\r
+be called something other than `show w' and `show c'; they could even be\r
+mouse-clicks or menu items--whatever suits your program.\r
+\r
+You should also get your employer (if you work as a programmer) or your\r
+school, if any, to sign a "copyright disclaimer" for the program, if\r
+necessary. Here is a sample; alter the names:\r
+\r
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program\r
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.\r
+\r
+ <signature of Ty Coon>, 1 April 1989\r
+ Ty Coon, President of Vice\r
+\r
+This General Public License does not permit incorporating your program into\r
+proprietary programs. If your program is a subroutine library, you may\r
+consider it more useful to permit linking proprietary applications with the\r
+library. If this is what you want to do, use the GNU Library General\r
+Public License instead of this License.\r

+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 6. Often, you can also type `make uninstall' to remove the installed
+ files again.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+
+DESCRIPTION
+ PolyGlot as adapter and book engine
+
+ PolyGlot is a "UCI adapter". It connects a GUI interface (such as
+ XBoard, Winboard, Arena or Chessbase) to a UCI chess engine.
+
+ By specifying an opening book (in PolyGlot book format) chess engines
+ can transparently use such books.
+
+ PolyGlot understands the two main GUI protocols: UCI and xboard. Nor-
+ mally the protocol will be auto detected but this can be overridden in
+ the configuration file.
+
+ In xboard mode PolyGlot fully translates between the xboard and UCI
+ protocols. In addition it tries to solve known problems with other
+ adapters. For instance, it detects and reports draws by fifty-move
+ rule, repetition, etc ... It also supports Chess960.
+
+ When in UCI mode PolyGlot mostly passes commands from the GUI to the
+ engine and vice versa, except that it will play book moves on behalf of
+ the engine when the occasion arises.
+
+ Book making utilities
+
+ PolyGlot supports the "PolyGlot opening book format". This is the
+ defacto standard non-proprietary opening book format. It is fully docu-
+ mented here
+
+ http://alpha.uhasselt.be/Research/Algebra/Toga/book_format.html
+
+ Roughly speaking a PolyGlot opening book is a collection of triples
+ (position, move, weight). A "position" is represented by a 64-bit
+ Zobrist hash key. The weight is proportional to the probability the
+ move should be played.
+
+ Other opening book formats such as ChessBase's .ctg format and Arena's
+ .abk format are undocumented and proprietary. They can only be used by
+ their own GUIs.
+
+ PolyGlot can compile a pgn file into a binary PolyGlot book and fur-
+ thermore it can merge two such binary books into a third one.
+
+ Epd test mode
+
+ In epd test mode, PolyGlot will search positions in an epd file and
+ record the number of times the right best move was found. The argu-
+ ments specify when to stop the search in any given position.
+
+ Perft counts
+
+ A perft count is the number of legal move sequence in a given position
+ up to a given depth. PolyGlot can perform such perft counts. It is how-
+ ever much slower than other more dedicated programs.
+
+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 invoked as
+
+ polyglot make-book
+
+ PolyGlot supports the following options
+
+ -pgn (default: "book.pgn")
+ Input file in pgn format.
+
+ -bin (default: "book.bin")
+ Output file in PolyGlot format.
+
+ -max-ply (default: 1024)
+ Specifies the maximum ply-depth of lines included in the book.
+
+ -min-game (default: 3)
+ Specifies the minimum number of games that have to contain this
+ move for it to be included in the book.
+
+ -min-score (default: 0.0)
+ Specifies the minimum score (or weight) this move should have
+ received for it to be included in the book. The score is
+ 2*(wins)+(draws), globally scaled to fit into 16 bits.
+
+ -only-white
+ Include only moves for white in the book.
+
+ -only-black
+ Include only moves for black in the book.
+
+ -uniform
+ Set all weights to 1. In other words, all moves will be selected
+ with equal probability.
+
+ When invoked as
+
+ polyglot merge-book
+
+ PolyGlot supports the following options
+
+ -in1
+ First input file (in PolyGlot book format).
+
+ -in2
+ Second input file (in PolyGlot book format).
+
+ -out (default: out.bin)
+ Output file (in PolyGlot book format).
+
+ Input files are not symmetrical, "in1" has priority over "in2". In
+ other words when a position occurs both in "in1" and "in2" only the
+ moves and weights from "in1" will be retained in "out".
+
+ When invoked as
+
+ polyglot epd-test
+
+ (possibly with a config file as first argument) PolyGlot supports the
+ following options
+
+ -max-depth (default: 63)
+ Unconditionally stop the search when this depth has been reached.
+
+ -max-time (default: 5.0)
+ Unconditionally stop the seach after this amount of time.
+
+ -depth-delta (default: 3)
+ Stop the search if the best move has been constant for this many
+ depths, on condition that the mininal depth and minimal time have
+ been reached.
+
+ -min-depth (default: 8)
+ Minimal search depth when the search is stopped using
+ "-depth-delta".
+
+ -min-time (default: 1.0)
+ Minimal search time when the search is stopped using
+ "-depth-delta".
+
+ When invoked as
+
+ polyglot perft
+
+ PolyGlot supports the following options
+
+ -fen (default: starting position)
+ Fen at which to start searching.
+
+ -max-depth (default: 1)
+ Maximum depth to search.
+
+CONFIG FILE FORMAT
+ There should be a different config file for each engine.
+
+ The config file is in the traditional INI format.
+
+ [PolyGLot]
+ option = value
+ ...
+ [Engine]
+ option = value
+ ...
+
+ Lines starting with "#" are ignored.
+
+ NOTE: There can be spaces in option names or values. Do not use
+ quotes. Boolean values are written as "true" or "false".
+
+ [PolyGlot] section
+
+ This section is used by PolyGlot only. The engine is unaware of these
+ options. The list of available options is detailed below.
+
+ EngineName (default: UCI name)
+ This is the name that will appear in the GUI. It is cosmetic only.
+ You can use different names for tweaked versions of the same
+ engine.
+
+ EngineDir (default: ".")
+ Full path of the directory where the engine is installed. You can
+ use "." (without the quotes) if you know that PolyGlot will be
+ launched in the engine directory or the engine is in the "path" and
+ does not need any data file.
+
+ EngineCommand
+ Put here the name of the engine executable file. You can also add
+ command-line arguments. Path searching is used and the current
+ directory will be "EngineDir".
+
+ Log (default: false)
+ Whether PolyGlot should log all transactions with the interface and
+ the engine. This should be necessary only to locate problems.
+
+ LogFile (default: polyglot.log)
+ The name of the log file. Note that it is put where PolyGlot was
+ launched from, not into the engine directory.
+
+ WARNING: Log files are not cleared between sessions, and can become
+ very large. It is safe to remove them though.
+
+ Resign (default: false)
+ Set this to "true" if you want PolyGlot to resign on behalf of the
+ engine.
+
+ NOTE: Some engines display buggy scores from time to time although
+ the best move is correct. Use this option only if you know what
+ you are doing (e.g. you always check the final position of games).
+
+ ResignMoves (default: 3)
+ Number of consecutive moves with "resign" score (see below) before
+ PolyGlot resigns for the engine. Positions with only one legal
+ move are ignored.
+
+ ResignScore (default: 600)
+ This is the score in centipawns that will trigger resign "count-
+ ing".
+
+ ShowPonder (default: true)
+ Show search information during engine pondering. Turning this off
+ might be better for interactive use in some interfaces.
+
+ KibitzMove (default: false)
+ Whether to kibitz when playing a move.
+
+ KibitzPV (default: false)
+ Whether to kibitz when the PV is changed (new iteration or new best
+ move).
+
+ KibitzCommand (default: "tellall")
+ xboard command to use for kibitzing, normally "tellall" for kibitz-
+ ing or "tellothers" for whispering.
+
+ KibitzDelay (default: 5)
+ How many seconds to wait before starting kibitzing. This has an
+ effect only if "KibitzPV" is selected, move kibitzes are always
+ sent regardless of the delay.
+
+ UCI (default: false)
+ If true PolyGlot will not understand xboard commands.
+
+ Book (default: false)
+ Indicates whether a PolyGlot book should be used. This has no
+ effect on the engine own book (which can be controlled with the UCI
+ option "OwnBook" in the [Engine] section). In particular, it is
+ possible to use both a PolyGlot book and an engine book. In that
+ case, the engine book will be used whenever PolyGlot is out of
+ book. Remember that PolyGlot is unaware of whether the engine is
+ itself using a book or not.
+
+ Chess960 (default: false)
+ Play Chess960 (also called Fischer Random Chess or FRC),
+
+ MateScore (default: 10000)
+ Mate score reported to GUI when in xboard mode.
+
+ BookFile (default: book.bin)
+ The name of the (binary) book file. Note that PolyGlot will look
+ for it in the directory it was launched from, not in the engine
+ directory. Of course, full path can be used in which case the cur-
+ rent directory does not matter.
+
+ NOTE: When using PolyGlot with a UCI GUI this parameter can be set
+ via the UCI option "Polyglot BookFile".
+
+ BookRandom (default: true)
+ Select moves according to their weights in the book. If false the
+ move with the highest weight is selected.
+
+ BookLearn (default: false)
+ Record learning information in the opening book. Naturally this
+ requires the opening book to be writable.
+
+ UseNice (default: false)
+ Run the engine at nice level 5, or "NiceValue" if it set. On some
+ operating systems it may be necessary to run the engine at lower
+ priority for it to be responsive to commands from PolyGlot while
+ searching.
+
+ NiceValue (default: 5)
+ Nice levels go from -20 to 20 with 20 being the lowest priority.
+ On Unix only root can set negative nice levels. On Windows the
+ standard Win32 priority levels are mapped in a sensible way to Unix
+ nice levels.
+
+ Affinity (default: -1)
+ 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.
+
+ 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 cor-
+ rect for bug-free software.
+
+ IMPORTANT: Any of these work arounds might be removed in future ver-
+ sions of PolyGlot. You are strongly recommended to contact the author
+ of faulty software and truly fix the problem.
+
+ PolyGlot supports the following work arounds:
+
+ UCIVersion (default: 2)
+ The default value of 2 corresponds to UCI+. Use 1 to select plain
+ UCI for engines that have problems with UCI+.
+
+ CanPonder (default: false)
+ PolyGlot now conforms to the documented UCI behaviour: the engine
+ will be allowed to ponder only if it (the engine) declares the
+ "Ponder" UCI option. However some engines which can actually pon-
+ der do not declare the option. This work around lets PolyGlot know
+ that they can ponder.
+
+ SyncStop (default: false)
+ When a ponder miss occurs, Polyglot interrupts the engine and IMME-
+ DIATELY launches a new search. While there should be no problem
+ with this, some engines seem confused and corrupt their search
+ board. "SyncStop" forces PolyGlot to wait for the (now useless)
+ ponder search to finish before launching the new search.
+
+ PromoteWorkAround (default: false)
+ Some engines do not specify a promotion piece, e.g. they send
+ "e7e8" instead of the correct "e7e8q". This work around enables
+ the incorrect form (and of course promotes into a queen).
+
+ 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.
+
+ [Engine] section
+
+ This section contains engine UCI options. PolyGlot does not understand
+ them, but sends the information to the engine at startup (converted to
+ UCI form). You can add any UCI option that makes sense to the engine
+ (not just the common options about hash-table size and tablebases).
+
+ NOTE: use INI syntax, not UCI. For example "OwnBook = true" is cor-
+ rect. It will be replaced by PolyGlot with "setoption name OwnBook
+ value true" at engine startup.
+
+ Standard UCI options are
+
+ Hash
+ NalimovPath
+ NalimovCache
+ OwnBook
+
+ Hidden options like "Ponder" or "UCI_xxx" are automatic and should not
+ be put in an INI file.
+
+ The other options are engine-specific. Check their name using a UCI
+ GUI or launch the engine in a console and type "uci".
+

+\r
+General\r
+-------\r
+\r
+PolyGlot 1.3 (2005/06/03).\r
+\r
+PolyGlot is a "UCI adapter". It connects a UCI chess engine to an\r
+xboard interface such as WinBoard. UCI2WB is another such adapter\r
+(for Windows).\r
+\r
+PolyGlot tries to solve known problems with other adapters. For\r
+instance, it detects and reports draws by fifty-move rule, repetition,\r
+etc ...\r
+\r
+\r
+Official distribution URL\r
+-------------------------\r
+\r
+The official distribution web site is Leo Dijksman's WBEC Ridderkerk:\r
+http://wbec-ridderkerk.nl/ This is where you should be looking for\r
+PolyGlot updates in the future.\r
+\r
+\r
+Install\r
+-------\r
+\r
+PolyGlot should have its own directory. The INI files for engines\r
+should also be put there. Dirtier solutions are needed when\r
+BookThinker is used though.\r
+\r
+On Windows the files "polyglot.exe" and "cygwin1.dll" (which you can\r
+download from http://wbec-ridderkerk.nl/) are needed. On Linux and\r
+Mac OS X only the file "polyglot_linux" or "polyglot_mac" is required.\r
+\r
+\r
+Compiling\r
+---------\r
+\r
+The distribution comes up with Windows, Linux and Mac OS X binaries.\r
+Compiling is therefore not necessary on those systems unless you want\r
+to make a change in the program. In any case this section describes\r
+the compiling procedure, it is safe to skip it.\r
+\r
+PolyGlot is a POSIX application (Unix compatible), and was developed\r
+on Linux using g++ (the GNU C++ compiler).\r
+\r
+1) Unix\r
+\r
+You should be able to compile it on any POSIX-compliant operating\r
+system (*not* Windows) with the following command line (or similar):\r
+\r
+> g++ -O2 -o polyglot *.cpp\r
+\r
+IMPORTANT: In "io.cpp", the variable "UseCR" should be set to "false".\r
+\r
+A Makefile is provided but might not work on your system ...\r
+\r
+2) Windows\r
+\r
+On Windows, you *must* use Cygnus GCC to compile PolyGlot.\r
+\r
+IMPORTANT: In "io.cpp", the variable "UseCR" should be set to "true".\r
+\r
+\r
+Usage\r
+-----\r
+\r
+PolyGlot acts as an xboard engine. There should be no difference with\r
+a normal chess program as far as the interface (e.g. WinBoard) is\r
+concerned.\r
+\r
+PolyGlot is invoked using "polyglot <INI file>". Note that PolyGlot\r
+will look for the INI file in the current directory. If no <INI file>\r
+is given, "polyglot.ini" is selected.\r
+\r
+To use PolyGlot with XBoard, you would type something like this:\r
+> xboard -fd 'polyglot_dir' -fcp 'polyglot engine.ini'\r
+\r
+Quotes are important when there is a space in the argument.\r
+\r
+\r
+INI file\r
+--------\r
+\r
+There should be a different INI file for each engine. Sections are\r
+composed of "variable = value" lines. See the sample INI files in the\r
+"example" directory.\r
+\r
+NOTE: There can be spaces in variable names or values. Do not use\r
+quotes.\r
+\r
+1) [PolyGlot] section\r
+\r
+This section is used by PolyGlot only. The engine is unaware of these\r
+options. The list of available options is detailed below in this\r
+document.\r
+\r
+2) [Engine] section\r
+\r
+This section contains engine UCI options. PolyGlot does not\r
+understand them, but sends the information to the engine at startup\r
+(converted to UCI form). You can add any UCI option that makes sense\r
+to the engine (not just the common options about hash-table size and\r
+tablebases).\r
+\r
+NOTE: use INI syntax, not UCI. For example "OwnBook = true" is\r
+correct. It will be replaced by PolyGlot with "setoption name OwnBook\r
+value true" at engine startup.\r
+\r
+Standard UCI options are "Hash", "NalimovPath", "NalimovCache" and\r
+"OwnBook". Hidden options like "Ponder" or "UCI_xxx" are automatic\r
+and should not be put in an INI file.\r
+\r
+The other options are engine-specific. Check their name using a UCI\r
+GUI or launch the engine in a console and type "uci".\r
+\r
+\r
+Options\r
+-------\r
+\r
+These should be put in the [PolyGlot] section.\r
+\r
+- "EngineName" (default: UCI name)\r
+\r
+This is the name that will appear in the xboard interface. It is\r
+cosmetic only. You can use different names for tweaked versions of\r
+the same engine.\r
+\r
+If no "Engine Name" is given, the UCI name will be used.\r
+\r
+- "EngineDir" (default: ".")\r
+\r
+Full path of the directory where the engine is installed. You can use\r
+"." (without the quotes) if you know that PolyGlot will be launched in\r
+the engine directory or the engine is in the "path" and does not need\r
+any data file.\r
+\r
+- "EngineCommand"\r
+\r
+Put here the name of the engine executable file. You can also add\r
+command-line arguments. Path searching is used and the current\r
+directory will be "EngineDir".\r
+\r
+NOTE: Unix users are recommended to prepend "./"; this is required on\r
+some secure systems.\r
+\r
+- "Log" (default: false)\r
+\r
+Whether PolyGlot should log all transactions with the interface and\r
+the engine. This should be necessary only to locate problems.\r
+\r
+- "LogFile"\r
+\r
+The name of the log file. Note that it is put where PolyGlot was\r
+launched from, not into the engine directory.\r
+\r
+WARNING: Log files are not cleared between sessions, and can become\r
+very large. It is safe to remove them though.\r
+\r
+- "Resign" (default: false)\r
+\r
+Set this to "true" if you want PolyGlot to resign on behalf of the\r
+engine.\r
+\r
+NOTE: Some engines display buggy scores from time to time although the\r
+best move is correct. Use this option only if you know what you are\r
+doing (e.g. you always check the final position of games).\r
+\r
+- "ResignMoves" (default: 3)\r
+\r
+Number of consecutive moves with "resign" score (see below) before\r
+PolyGlot resigns for the engine. Positions with only one legal move\r
+are ignored.\r
+\r
+- "ResignScore" (default: 600)\r
+\r
+This is the score in centipawns that will trigger resign "counting".\r
+\r
+- "ShowPonder" (*** NEW ***, default: true)\r
+\r
+Show search information during engine pondering. Turning this off\r
+might be better for interactive use in some interfaces.\r
+\r
+- "KibitzMove" (*** NEW ***, default: false)\r
+\r
+Whether to kibitz when playing a move.\r
+\r
+- "KibitzPV" (*** NEW ***, default: false)\r
+\r
+Whether to kibitz when the PV is changed (new iteration or new best move).\r
+\r
+- "KibitzCommand" (*** NEW ***, default: "tellall")\r
+\r
+xboard command to use for kibitzing, normally "tellall" for kibitzing\r
+or "tellothers" for whispering.\r
+\r
+- "KibitzDelay" (*** NEW ***, default: 5)\r
+\r
+How many seconds to wait before starting kibitzing. This has an\r
+affect only if "KibitzPV" is selected, move kibitzes are always sent\r
+regardless of the delay.\r
+\r
+\r
+Work arounds\r
+------------\r
+\r
+Work arounds are identical to options except that they should be used\r
+only when necessary. Their purpose is to try to hide problems with\r
+various software (not just engines). The default value is always\r
+correct for bug-free software.\r
+\r
+IMPORTANT: Any of these work arounds might be removed in future\r
+versions of PolyGlot. You are strongly recommended to contact the\r
+author of faulty software and truly fix the problem.\r
+\r
+In PolyGlot 1.3 there is only one optional work around:\r
+\r
+- "UCIVersion" (default: 2)\r
+\r
+The default value of 2 corresponds to UCI+. Use 1 to select plain\r
+UCI for engines that have problems with UCI+.\r
+\r
+\r
+Opening Book\r
+------------\r
+\r
+*** NEW ***\r
+\r
+PolyGlot 1.3 provides a minimal opening-book implementation.\r
+\r
+New options can be added to the [PolyGlot] section:\r
+\r
+- "Book" (default: false)\r
+\r
+Indicates whether a PolyGlot book should be used. This has no effect\r
+on the engine own book (which can be controlled with the UCI option\r
+"OwnBook" in the [Engine] section). In particular, it is possible to\r
+use both a PolyGlot book and an engine book. In that case, the engine\r
+book will be used whenever PolyGlot is out of book. Remember that\r
+PolyGlot is unaware of whether the engine is itself using a book or\r
+not.\r
+\r
+- "BookFile"\r
+\r
+The name of the (binary) book file. Note that PolyGlot will look for\r
+it in the directory it was launched from, not in the engine directory.\r
+Of course, full path can be used in which case the current directory\r
+does not matter.\r
+\r
+Note that there is no option to control book usage. All parameters\r
+are fixed when compiling a PGN file into a binary book (see below).\r
+This is purposeful and is not likely to change.\r
+\r
+Using a book does not require any additional memory, this can be\r
+important for memory-limited tournaments.\r
+\r
+A default book "fruit.bin" is provided in the archive. Note that this\r
+book is very small and should probably not be used in serious games.\r
+I hope that users will make other books available in the future.\r
+\r
+\r
+Book Making\r
+-----------\r
+\r
+*** NEW ***\r
+\r
+You can compile a PGN file into a binary book using PolyGlot on the\r
+command line. At the moment, only a main (random) book is provided.\r
+It is not yet possible to control opening lines manually. I am\r
+working on it though.\r
+\r
+Usage: "polyglot make-book <options>".\r
+\r
+"make-book" options are:\r
+\r
+- "-pgn"\r
+\r
+Name of the input PGN file. PolyGlot should support any\r
+standard-conforming file. Let me know if you encounter a problem.\r
+\r
+- "-bin"\r
+\r
+Name of the output binary file. I suggest ".bin" as the extension but\r
+in fact PolyGlot does not care.\r
+\r
+- "-max-ply" (default: infinite)\r
+\r
+How many plies (half moves) to read for each game. E.g. if set to\r
+"20", only the first 10 full moves of each game will be scanned.\r
+\r
+- "-min-game" (default: 3)\r
+\r
+How many times must a move be played to be kept in the book. In other\r
+words, moves that were played too rarely will be left out. If you\r
+scan full games "2" seems a minimum, but if you selected lines\r
+manually "1" will make sense.\r
+\r
+Example: "polyglot make-book -pgn games.pgn -bin book.bin -max-ply 30".\r
+\r
+Building a book is usually very fast (a few minutes at most). Note\r
+however that a lot of memory may be required. To reduce memory usage,\r
+select a ply limit.\r
+\r
+\r

+\r
+\r
+Known bugs\r
+----------\r
+\r
+*** IMPORTANT ***\r
+\r
+There is a bug (!) in the xboard automaton. The bug is related to\r
+searching in draw positions (e.g. 50-move rule or repetition). I had\r
+only been able to make PolyGlot crash by using analysis mode and\r
+performing manual takebacks. I believe that this bug can only happen\r
+in highly-interactive use (e.g. manual analysis). It is present in\r
+all versions of PolyGlot, including this one.\r
+\r
+I attempted a work around in February. I vaguely remember the change\r
+prevents crashing (not sure) but it is possible that PolyGlot now gets\r
+stuck in some rare case, i.e. it refuses to produce a move. In any\r
+case, the bug cannot occur silently, e.g. in a game that terminated\r
+normally.\r
+\r
+Because of the small expected impact (nobody ever reported it to me)\r
+and because fixing the bug would require a whole redesign of the\r
+xboard module, I have no intention of working on it at the moment (!).\r
+\r
+Make sure to let me know if it appeared in any circounstance, thanks!\r
+In particular if the bug ever occurs during a non-interactive session\r
+(e.g. engine vs. engine game), then I will do something.\r
+\r

+General
+-------
+
+PolyGlot 1.4 (2006/01/16).
+
+PolyGlot is a "UCI adapter". It connects a UCI chess engine to an
+xboard interface such as WinBoard. UCI2WB is another such adapter
+(for Windows).
+
+PolyGlot tries to solve known problems with other adapters. For
+instance, it detects and reports draws by fifty-move rule, repetition,
+etc ...
+
+
+Official distribution URL
+-------------------------
+
+The official distribution web site is Leo Dijksman's WBEC Ridderkerk:
+http://wbec-ridderkerk.nl/ This is where you should be looking for
+PolyGlot updates in the future.
+
+
+Install
+-------
+
+PolyGlot can be placed in its own directory, or anywhere it can access
+the DLL file from (on Windows).
+
+On Windows the files "polyglot.exe" and "cygwin1.dll" (which you can
+download from http://wbec-ridderkerk.nl/) are needed. On Linux and
+Mac OS X only the file "polyglot_linux" or "polyglot_mac" is required.
+
+
+Compiling
+---------
+
+The distribution comes up with Windows, Linux and Mac OS X binaries.
+Compiling should therefore not be necessary on those systems unless
+you want to make a change in the program. In any case this section
+describes the compiling procedure, it is safe to skip it.
+
+PolyGlot is a POSIX application (Unix compatible), and was developed
+on Linux using g++ (the GNU C++ compiler).
+
+1) Unix
+
+You should be able to compile it on any POSIX-compliant operating
+system (*not* Windows) with the following command line (or similar):
+
+> g++ -O2 -o polyglot *.cpp
+
+IMPORTANT: In "io.cpp", the variable "UseCR" should be set to "false".
+
+A Makefile is provided but might not work on your system ...
+
+2) Windows
+
+On Windows, you *must* use Cygnus GCC to compile PolyGlot.
+
+IMPORTANT: In "io.cpp", the variable "UseCR" should be set to "true".
+
+
+Usage
+-----
+
+PolyGlot acts as an xboard engine. There should be no difference with
+a normal chess program as far as the interface (e.g. WinBoard) is
+concerned.
+
+PolyGlot is invoked using "polyglot ". Note that PolyGlot
+will look for the INI file in the current directory. If no
+is given, "polyglot.ini" is selected.
+
+To use PolyGlot with XBoard, you would type something like this:
+> xboard -fd 'ini_dir' -fcp 'polyglot engine.ini'
+
+Quotes are important when there is a space in the argument.
+
+IMPORTANT: some users seem confused by the concept of "current
+directory". PolyGlot needs to know where to read (INI file) and write
+(log file) files. Although it's possible to specify the full path to
+each file, a better solution is to provide a directory when launching
+PolyGlot, e.g. with the "-fd" XBoard option above. The directory
+should be where the INI file is.
+
+
+INI file
+--------
+
+There should be a different INI file for each engine. Sections are
+composed of "variable = value" lines. See the sample INI files in the
+"example" directory.
+
+NOTE: There can be spaces in variable names or values. Do not use
+quotes.
+
+1) [PolyGlot] section
+
+This section is used by PolyGlot only. The engine is unaware of these
+options. The list of available options is detailed below in this
+document.
+
+2) [Engine] section
+
+This section contains engine UCI options. PolyGlot does not
+understand them, but sends the information to the engine at startup
+(converted to UCI form). You can add any UCI option that makes sense
+to the engine (not just the common options about hash-table size and
+tablebases).
+
+NOTE: use INI syntax, not UCI. For example "OwnBook = true" is
+correct. It will be replaced by PolyGlot with "setoption name OwnBook
+value true" at engine startup.
+
+Standard UCI options are "Hash", "NalimovPath", "NalimovCache" and
+"OwnBook". Hidden options like "Ponder" or "UCI_xxx" are automatic
+and should not be put in an INI file.
+
+The other options are engine-specific. Check their name using a UCI
+GUI or launch the engine in a console and type "uci".
+
+
+Options
+-------
+
+These should be put in the [PolyGlot] section.
+
+- "EngineName" (default: UCI name)
+
+This is the name that will appear in the xboard interface. It is
+cosmetic only. You can use different names for tweaked versions of
+the same engine.
+
+If no "Engine Name" is given, the UCI name will be used.
+
+- "EngineDir" (default: ".")
+
+Full path of the directory where the engine is installed. You can use
+"." (without the quotes) if you know that PolyGlot will be launched in
+the engine directory or the engine is in the "path" and does not need
+any data file.
+
+- "EngineCommand"
+
+Put here the name of the engine executable file. You can also add
+command-line arguments. Path searching is used and the current
+directory will be "EngineDir".
+
+NOTE: Unix users are recommended to prepend "./"; this is required on
+some secure systems.
+
+- "Log" (default: false)
+
+Whether PolyGlot should log all transactions with the interface and
+the engine. This should be necessary only to locate problems.
+
+- "LogFile"
+
+The name of the log file. Note that it is put where PolyGlot was
+launched from, not into the engine directory.
+
+WARNING: Log files are not cleared between sessions, and can become
+very large. It is safe to remove them though.
+
+- "Resign" (default: false)
+
+Set this to "true" if you want PolyGlot to resign on behalf of the
+engine.
+
+NOTE: Some engines display buggy scores from time to time although the
+best move is correct. Use this option only if you know what you are
+doing (e.g. you always check the final position of games).
+
+- "ResignMoves" (default: 3)
+
+Number of consecutive moves with "resign" score (see below) before
+PolyGlot resigns for the engine. Positions with only one legal move
+are ignored.
+
+- "ResignScore" (default: 600)
+
+This is the score in centipawns that will trigger resign "counting".
+
+- "ShowPonder" (default: true)
+
+Show search information during engine pondering. Turning this off
+might be better for interactive use in some interfaces.
+
+- "KibitzMove" (default: false)
+
+Whether to kibitz when playing a move.
+
+- "KibitzPV" (default: false)
+
+Whether to kibitz when the PV is changed (new iteration or new best move).
+
+- "KibitzCommand" (default: "tellall")
+
+xboard command to use for kibitzing, normally "tellall" for kibitzing
+or "tellothers" for whispering.
+
+
+- "KibitzDelay" (default: 5)
+
+How many seconds to wait before starting kibitzing. This has an
+affect only if "KibitzPV" is selected, move kibitzes are always sent
+regardless of the delay.
+
+
+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.
+
+IMPORTANT: Any of these work arounds might be removed in future
+versions of PolyGlot. You are strongly recommended to contact the
+author of faulty software and truly fix the problem.
+
+PolyGlot 1.4 supports the following work arounds:
+
+- "UCIVersion" (default: 2)
+
+The default value of 2 corresponds to UCI+. Use 1 to select plain
+UCI for engines that have problems with UCI+.
+
+- "CanPonder" (*** NEW ***, default: false)
+
+PolyGlot now conforms to the documented UCI behaviour: the engine will
+be allowed to ponder only if it (the engine) declares the "Ponder" UCI
+option. However some engines which can actually ponder do not declare
+the option. This work around lets PolyGlot know that they can ponder.
+
+- "SyncStop" (*** NEW ***, default: false)
+
+When a ponder miss occurs, Polyglot interrupts the engine and
+IMMEDIATELY launches a new search. While there should be no problem
+with this, some engines seem confused and corrupt their search board.
+"SyncStop" forces PolyGlot to wait for the (now useless) ponder search
+to finish before launching the new search.
+
+- "PromoteWorkAround" (*** NEW ***, default: false)
+
+Some engines do not specify a promotion piece, e.g. they send "e7e8"
+instead of the correct "e7e8q". This work around enables the
+incorrect form (and of course promotes into a queen).
+
+
+Opening Book
+------------
+
+PolyGlot 1.4 provides a simplistic opening-book implementation.
+
+The following options can be added to the [PolyGlot] section:
+
+- "Book" (default: false)
+
+Indicates whether a PolyGlot book should be used. This has no effect
+on the engine own book (which can be controlled with the UCI option
+"OwnBook" in the [Engine] section). In particular, it is possible to
+use both a PolyGlot book and an engine book. In that case, the engine
+book will be used whenever PolyGlot is out of book. Remember that
+PolyGlot is unaware of whether the engine is itself using a book or
+not.
+
+- "BookFile"
+
+The name of the (binary) book file. Note that PolyGlot will look for
+it in the directory it was launched from, not in the engine directory.
+Of course, full path can be used in which case the current directory
+does not matter.
+
+Note that there is no option to control book usage. All parameters
+are fixed when compiling a PGN file into a binary book (see below).
+This is purposeful and is not likely to change.
+
+Using a book does not require any additional memory, this can be
+important for memory-limited tournaments.
+
+A default book "fruit.bin" is provided in the archive. Note that this
+book is very small and should probably not be used in serious games.
+I hope that users will make other books available in the future.
+
+
+Book Making
+-----------
+
+You can compile a PGN file into a binary book using PolyGlot on the
+command line. At the moment, only a main (random) book is provided.
+It is not yet possible to control opening lines manually. I am
+working on it though.
+
+Usage: "polyglot make-book ".
+
+"make-book" options are:
+
+- "-pgn"
+
+Name of the input PGN file. PolyGlot should support any
+standard-conforming file. Let me know if you encounter a problem.
+
+- "-bin"
+
+Name of the output binary file. I suggest ".bin" as the extension but
+in fact PolyGlot does not care.
+
+- "-max-ply" (default: infinite)
+
+How many plies (half moves) to read for each game. E.g. if set to
+"20", only the first 10 full moves of each game will be scanned.
+
+- "-min-game" (default: 3)
+
+How many times must a move be played to be kept in the book. In other
+words, moves that were played too rarely will be left out. If you
+scan full games "2" seems a minimum, but if you selected lines
+manually "1" will make sense.
+
+- "-only-white" *** NEW ***
+
+Save only white moves. This allows to use different parameters for
+white and black books, and merge them into a single file with the
+"merge-book" command, see below.
+
+- "-only-black" *** NEW ***
+
+Same for black moves.
+
+- "-uniform" *** NEW ***
+
+By default, a probability is calculated by PolyGlot for each move
+depending on how popular it is (how often it was playing in the
+provided PGN file) and how much it "scored". This option bypasses the
+default mechanism and affects equal probability to all moves. This
+allows more variety of play.
+
+This option is normally used only with hand-selected lines (e.g. "user
+books").
+
+---
+
+Example: "polyglot make-book -pgn games.pgn -bin book.bin -max-ply 30".
+
+Building a book is usually very fast (a few minutes at most). Note
+however that a lot of memory may be required. To reduce memory usage,
+select a ply limit.
+
+
+Book Merging
+------------
+
+*** NEW ***
+
+Usage: "polyglot merge-book -in1 -in2 -out "
+
+Merge two bin files into a single one. has "priority"; this
+means that if a position is present in both input books, data from
+ will be ignored for this position.
+
+The two main applications are:
+
+1) combine a white book and a black book (in which case priority does
+ not matter)
+
+2) combine a "user book" of manually-selected lines with a broader one
+ from a large game set
+
+What follows is an admitedly complicated example of how this can be
+used. DO NOT MAILBOMB ME IF YOU DO NOT UNDERSTAND!
+
+My hope is that at least one advanced user will get what I mean and
+writes a better explanation on a web page or forum thread (yes, that's
+YOU, thanks by the way) ...
+
+---
+
+Imagine that we've got 4 PGN files as follows:
+
+w1.pgn: fixed white lines, all moves manually checked
+w2.pgn: selected games (for random book as with PolyGlot 1.3)
+
+b1.pgn and b2.pgn: same for black
+
+The first step is to build 4 .bin files with appropriate options.
+Lines starting with "> " indicate what is typed on the command line.
+
+> polyglot make-book -min-game 1 -uniform -only-white -pgn w1.pgn -bin w1.bin
+
+I added "-uniform" because it allows randomness in the fixed lines
+(e.g. d4+e4 at 50%). It has no effect if lines are deterministic
+(only one move for a given position).
+
+"-min-game 1" is characteristic for user books. All moves are supposed
+to be safe so there is no reason to filter them with other heuristics.
+
+> polyglot make-book -min-score 50 -only-white -pgn w2.pgn -bin w2.bin
+
+This shows how min-score can actually be different for white and black
+(as with multiple books). I don't use "max-ply" because "min-game"
+default value of 3 will limit depth somewhat. You are of course free
+to use it.
+
+Same for black:
+
+> polyglot make-book -min-game 1 -uniform -only-black -pgn b1.pgn -bin b1.bin
+> polyglot make-book -min-score 40 -only-black -pgn b2.pgn -bin b2.bin
+
+At this point we have 4 .bin files. Notice that different parameters
+were used for white and for black (not to mention that different PGN
+files can be used).
+
+---
+
+Let's now merge the white books.
+
+> polyglot merge-book -in1 w1.bin -in2 w2.bin -out w.bin
+
+Input files are not symmetrical, "in1" has priority over "in2".
+
+"skipped xxx entries." message from PolyGlot means there were some
+position conflicts. This is normal since we want to overwrite some
+random moves with fixed lines instead.
+
+Same for black:
+
+> polyglot merge-book -in1 b1.bin -in2 b2.bin -out b.bin
+
+Now we can finally merge the white and black books.
+
+> polyglot merge-book -in1 w.bin -in2 b.bin -out book.bin
+
+It's important to check that there are no conflicts, otherwise
+something went wrong.
+
+Note that this last operation was only made possible thanks to colour
+filtering, otherwise nearly all positions would lead to conflicts.
+For this reason, it does not make much sense to mix old .bin files
+(which contain moves for both colours).
+
+All these command lines might seem numerous and complicated but they
+can be put together into batch files.
+
+
+Chess 960
+---------
+
+*** NEW ***
+
+PolyGlot now supports Chess 960.
+
+However note that most xboard interfaces like WinBoard do not (except
+perhaps on an Internet chess server)!
+
+Here are pointers to modified XBoard/WinBoard versions that are known
+to work with PolyGlot in Chess960 mode:
+
+http://www.ascotti.org/programming/chess/winboard_x.htm (Windows)
+http://www.glaurungchess.com/xboard-960.tar.bz2 (Unix)
+http://www.milix.net/aice (?)
+
+It is also possible that PolyGlot is useful in combination with
+Arena(!): Arena Chess960 works correctly in xboard mode but it seems
+not compatible with the official UCI standard. With PolyGlot it is
+possible to include Chess960 UCI engines by using the xboard protocol
+instead.
+
+
+History
+-------
+
+2004/04/30: PolyGlot 1.0
+
+- first public release.
+
+2004/10/01: PolyGlot 1.1
+
+- added "StartupWait" and "PonderWorkAround" ("AutoQuit" was available
+ in version 1.0 but not documented).
+
+- fixed a minor bug that could prevent "AutoQuit" from working with
+ some engines.
+
+2005/01/29: PolyGlot 1.2
+
+- rewrote engine initialisation and UCI parsing to increase
+ UCI-standard compliance
+
+- added multi-move resign
+
+- added an internal work around for engines hanging with WinBoard
+
+2005/06/03: PolyGlot 1.3
+
+- added opening book
+
+- added kibitzing
+
+- added "ShowPonder" option
+
+2006/01/16: PolyGlot 1.4
+
+- added Chess960 (requires "fischerandom" xboard variant)
+
+- added "-only-white", "-only-black" and "-uniform" book-making
+ options
+
+- added "merge-book" command
+
+- added "CanPonder", "SyncStop" and "PromoteWorkAround" work arounds
+
+- fixed "Move Now" (the engine was interrupted but the move was
+ ignored)
+
+- fixed an UCI+draw problem that could occur with some engines after a
+ draw by 50 moves or repetition
+
+- fixed pondering behaviour: the engine will ponder only if it
+ declares the "Ponder" UCI option
+
+
+Known problems
+--------------
+
+The addition of Chess960 support lead to a change in internal-move
+representation for castling. This slightly affected the opening-book
+format. I recommend that you recompile books with this version.
+
+Fruit 2.2 and above handle both book formats though.
+
+---
+
+Several users reported engines losing on time. The playing conditions
+always mixed playing on an Internet server with pondering. Early
+log-file analysis did not reveal any misbehaviour by PolyGlot, but I
+have others to study.
+
+It is not yet clear what the source of the problem is, but let me
+state one more time that there is a forever incompatibility between
+the xboard and UCI protocol regarding a complex
+pondering/remaining-time relation. I suspect this might be related to
+the problem described above and if so, it is possible that there is no
+clean solution to it!
+
+In any case I have other log file to study that might reveal
+something, stay tuned!

+Description
+===========
+
+This is an enhanced version of Polyglot 1.4w10 which can be used as a book
+engine for Polyglot books on UCI GUIs. It also has some additional features
+(see below).
+
+Some GUIs like ChessBase do not support Winboard engines at all. Other
+GUIs do support the Winboard protocol (like Arena) but you still lose
+the convenience of setting UCI options through the GUI.
+
+This new version of Polyglot is fully backward compatible and will in
+fact under normal circumstances autodetect the protocol.
+
+The following is a minimal polyglot.ini file to make an engine use
+Polyglot books.
+
+[Polyglot]
+EngineCommand = <path to engine>
+[Engine]
+
+By default this does not use any book but you can set the Polyglot book
+in the GUI through the exported UCI option "Polyglot BookFile".
+
+Any normal polyglot.ini file can be used with this version. The UCI
+options you set in the [Engine] section will be honored and the
+results will be shown in the GUI as "defaults".
+
+If you want to override the protocol autodetection (which should
+normally not be necessary) you can put
+
+UCI = true
+
+in the [Polyglot] section.
+
+Just like 1.4w10, this version of Polyglot compiles both under Linux
+and Windows.
+
+Some notes on Arena
+===================
+
+Up to version 1.99b5 Arena contained a bug with drive letters in UCI
+options. This bug has been fixed in 2.00.
+
+If you let Arena autodetect the engine type then it will use Polyglot
+in Winboard mode. So either configure the Polyglot adapter explicitly
+as a UCI engine in the Arena GUI, or else put UCI = true in the
+[Polyglot] section of polyglot.ini.
+
+
--- /dev/null
+Better check for legality of arguments (i.e. stuff after [configfile]).
+Implementation of new wb/xb options
+GUI mode
+Allow buttons in UCI mode
+Set book [none] instead of nothing as it is now.

+# Of course, Automake must honor this variable whenever it calls a

+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since

+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir

+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+<h1>Polyglot book format</h1>
+The following description of the Polyglot book format is obtained
+by inspecting the freely available source code of Polyglot.
+<h2>A note on copyright</h2> I believe that the algorithm described
+below may be freely implemented by all GUIs, adapters and engines,
+including closed source ones. Polyglot itself is GPL but the GPL only
+covers actual code and not algorithms.
+<p>
+The array of 781 random numbers is of course taken from the Polyglot
+source code but I am pretty sure that a table of random numbers
+cannot be covered by copyright.
+<p>
+Look below for some sample code which is released
+in the public domain.
+<p>
+At the end of this document we discuss an extension of the Polyglot
+opening book format for Chess960. This extension is implemented in
+upcoming versions of xboard/winboard.
+<h2>Outline</h2>
+A Polyglot book is a series of "entries" of 16 bytes
+<p>
+<pre>
+key uint64
+move uint16
+weight uint16
+learn uint32
+</pre>
+<p>
+All integers are stored highest byte first (regardless of size)
+<p>
+The entries are ordered according to key. Lowest key first.
+<p>
+<h2>key</h2>
+"key" is a 64 bit hash of a board position. Its computation
+is explained below.
+<p>
+The starting point is given by the following declaration
+
+<pre>

+The array Random64 is in fact a concatenation of four subarrays
+<pre>
+RandomPiece (offset: 0, length: 768)
+RandomCastle (offset: 768, length: 4)
+RandomEnPassant (offset: 772, length: 8)
+RandomTurn (offset: 780, length: 1)
+</pre>
+"key" is a so-called "Zobrist hash function". In other words it is
+the <b>exclusive or</b> of entries taken from each of the
+subarrays described above.
+
+Thus we have
+<pre>
+key=piece^castle^enpassant^turn;
+</pre>
+
+<h3>piece</h3>
+"piece" is the exclusive or of entries from
+RandomPiece, one for each piece on the board. The offset of the entry
+in RandomPiece corresponding to a piece is computed as follows.
+<pre>
+offset_piece=64*kind_of_piece+8*row+file;
+</pre>
+"row" and "file" are counted from 0 to 7. With this convention one has
+<pre>
+square file row
+======================
+a1 0 0
+h1 7 0
+a8 0 7
+h8 7 7
+</pre>
+
+"kind_of_piece" is encoded as follows
+<pre>
+black pawn 0
+white pawn 1
+black knight 2
+white knight 3
+black bishop 4
+white bishop 5
+black rook 6
+white rook 7
+black queen 8
+white queen 9
+black king 10
+white king 11
+</pre>
+
+<h3>castle</h3>
+"castle" is the exclusive or of entries from
+RandomCastle. The offsets are computed as follows.
+<pre>
+white can castle short 0
+white can castle long 1
+black can castle short 2
+black can castle long 3
+</pre>
+If none of these flags apply then castle=0.
+<p>
+Note that these flags represent "potential future castling" as in the
+FEN standard even if such castling is currently not possible due to blocking
+pieces or enemy attacks.
+<p>
+In other words these flags are all true in the starting position and are
+only updated after the appropriate king, rook or castling moves.
+
+
+
+<h3>enpassent</h3> If the opponent has performed a double pawn push
+and there is now a pawn next to it belonging to the player to move then
+"enpassant" is the entry from RandomEnPassant whose offset is the file
+of the pushed pawn (counted from 0(=a) to 7(=h)). If this does not
+apply then enpassant=0.
+<p>
+Note that this is <b>different from the FEN standard</b>. In the FEN standard
+the presence of an "en passant target square" after a double pawn push
+is unconditional.
+<p> Also note that it is irrelevant if the potential en passant
+capturing move is legal or not (examples where it would not be legal are
+when the capturing pawn is pinned or when the double pawn push was a
+discovered check).
+
+
+<h3>turn</h3>
+If white is to move then "turn" is the sole entry of RandomTurn.
+If not then "turn" is zero.
+
+<h3>Test data</h3>
+Here are some test keys. They were computed using Toga II
+and checked using the algorithm described above.

+<h2>move</h2>
+"move" is a bit field with the following meaning (bit 0 is the least
+significant bit)
+<pre>
+bits meaning
+===================================
+0,1,2 to file
+3,4,5 to row
+6,7,8 from file
+9,10,11 from row
+12,13,14 promotion piece
+</pre>
+"promotion piece" is encoded as follows
+<pre>
+none 0
+knight 1
+bishop 2
+rook 3
+queen 4
+</pre>
+If the move is "0" (a1a1) then it should simply be ignored. It seems to me that
+in that case one might as well delete the entry from the book.
+
+<h3>Castling moves</h3> Castling moves are represented somewhat
+unconventially as follows (this convention is related to Chess960, see
+below).
+<pre>
+white short e1h1
+white long e1a1
+black short e8h8
+black long e8a8
+</pre>
+It is technically possible that these moves are legal non-castling
+moves. So before deciding that these are really castling moves the
+implementation may for example verify that there is really a king
+present on e1/e8.
+<h2>weight</h2>
+In the Polyglot source code this field is called "count" but it is in fact
+a measure for the quality of the move. <b>It should be at least one.</b>
+<p>
+The Polyglot book generator sets it to 2*(wins)+(draws), globally
+scaled to fit into 16 bits. A move with a weight of zero is deleted
+from the book. This is just a convention and book authors
+are free to set this field according to their taste (as long as it is at least one).
+<p>
+If random play is enabled in Polyglot then the probability that
+a move is selected is its weight divided by the sum of the weights
+of all the moves in the given position.
+<h3>A note on zero weights</h3>
+Polyglot assumes that weights are at least one since a zero
+weight means the move should not be played, and hence you might as
+well delete the entry from the book (which the Polyglot book generator does).
+
+Nonetheless, if you really insist, an entry with zero weight can be
+approximated by giving it very low probability. This is what Scid does.
+
+<h2>learn</h2> "learn" is set to zero by the Polyglot book generator.
+If you set "BookLearn=true" in polyglot.ini then this field
+is used to record learning information. However I do not know of any
+program that uses this information. Also this means the Polyglot should
+have write access to the opening book which on Unix systems will probably
+not be the case if the book has been installed centrally.
+<p>
+<h2>Sample code</h2>
+The following sample code is released in the public domain.
+<ul>
+<li>
+<a href=pg_key.c>pg_key.c</a>: This little utility computes the PG key
+of a FEN. Note that it does ZERO error checking on the legality
+of the FEN and hence will segfault if something is wrong.
+</li>
+<li>
+<a href=pg_show.c>pg_show.c</a>: This utility looks up a PG key in a PG book
+and prints out the moves and their (relative) weights.
+</li>
+</ul>
+<h2>Utilities</h2>
+Here are a few utilities: <a href=pg_utils-0.2.tar.gz>pg_utils-0.2.tar.gz</a>. They are released under the FreeBSD license.
+<H2>Extension to Chess960</H2>
+We assume that the reader is familar
+with the rules of Chess960 (also called Fisher Random Chess or
+FRC). See e.g.
+<a href=http://en.wikipedia.org/wiki/Fischer_Random_Chess>http://en.wikipedia.org/wiki/Fischer_Random_Chess</a>.
+<p>
+The Zobrist hash function used in Polyglot does not keep track of
+which rook has castling rights if there are multiple rooks present on
+the same side of the king. However it is rather unlikely that this
+situation would occur in the opening. So the ambiguity can be resolved
+in a satisfactory way by making the following convention.
+<p>
+<b> Positions in which a rook has castling rights which is not an outer
+rook (closest to a or h file) should not be included in the book. </b>
+<p>
+Nonetheless this is an unsatisfactory situation. Therefore the
+upcoming versions of xboard/winboard extend the Polyglot hash function
+in such a way that it takes into account the full castling rights in
+Chess960, therefore
+<b>removing the need of the above disambiguating convention</b>. This is done in a backward compatible way. I.e. ordinary
+chess positions or Chess960 positions in which there is no castling
+ambiguity will keep their old hash key.
+<p>
+The above declaration of RandomCastle is replaced by
+<pre>
+const uint64 RandomCastle[16]={
+< to be filled in >
+}
+</pre>
+In this case "castle" will be the exclusive or of entries taken from
+RandomCastle, one for each rook that has castling rights (so at most
+four offsets).
+
+The offset for a rook that has castling rights is computed as follows.
+<ul>
+<li> If the rook is an outer rook (i.e. closest to the a or h file) then
+the offset is
+<pre>
+0 if the rook is white and on the king side
+1 if the rook is white and on the queen side
+2 if the rook is black and on the king side
+3 if the rook is black and on the queen side
+</pre>
+(this is like in ordinary chess)
+</li>
+<li> If the rook is not an outer rook then the offset is
+<pre>
+3+file if the rook is white
+9+file if the rook is black
+</pre>
+where "file" denotes the file the rook is on, encoded in the usual way, i.e.
+b=1,c=2,d=3,e=4,f=5,g=6.
+</li>
+</ul>
+<h3>Encoding of moves</h3> A castling move is encoded as a usual move
+(see above) in which the "from square" is the position of the king and
+the "to square" is the position of the rook. This is to maintain
+compatibility with various Fruit derivatives.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+=head1 DESCRIPTION
+
+=head2 PolyGlot as adapter and book engine
+
+PolyGlot is a "UCI adapter". It connects a GUI interface (such as
+XBoard, Winboard, Arena or Chessbase) to a UCI chess engine.
+
+By specifying an opening book (in PolyGlot book format) chess engines can
+transparently use such books.
+
+PolyGlot understands the two main GUI protocols: UCI and
+xboard. Normally the protocol will be auto detected but this can be
+overridden in the configuration file.
+
+In xboard mode PolyGlot fully translates between the xboard and UCI protocols.
+In addition it tries to solve known problems with other adapters.
+For instance, it detects and reports draws by fifty-move rule,
+repetition, etc ... It also supports Chess960.
+
+When in UCI mode PolyGlot mostly passes commands from the GUI
+to the engine and vice versa, except that it will play book moves on
+behalf of the engine when the occasion arises.
+
+=head2 Book making utilities
+
+PolyGlot supports the "PolyGlot opening book format". This is the
+defacto standard non-proprietary opening book format. It is fully documented
+here
+
+http://alpha.uhasselt.be/Research/Algebra/Toga/book_format.html
+
+Roughly speaking a PolyGlot opening book is a collection of triples
+(position, move, weight). A "position" is represented by a 64-bit
+Zobrist hash key. The weight is proportional to the probability the move should
+be played.
+
+Other opening book formats such as ChessBase's .ctg format and Arena's
+.abk format are undocumented and proprietary. They can only be used
+by their own GUIs.
+
+PolyGlot can compile a pgn file into a binary PolyGlot book and furthermore
+it can merge two such binary books into a third one.
+
+=head2 Epd test mode
+
+In epd test mode, PolyGlot will search positions in an epd file and
+record the number of times the right best move was found. The
+arguments specify when to stop the search in any given position.
+
+=head2 Perft counts
+
+A perft count is the number of legal move sequence in a given position
+up to a given depth. PolyGlot can perform such perft counts. It
+is however much slower than other more dedicated programs.

+doing (e.g. you always check the final position of games).
+
+=item B<ResignMoves> (default: 3)
+
+Number of consecutive moves with "resign" score (see below) before
+PolyGlot resigns for the engine. Positions with only one legal move
+are ignored.
+
+=item B<ResignScore> (default: 600)
+
+This is the score in centipawns that will trigger resign "counting".
+
+=item B<ShowPonder> (default: true)
+
+Show search information during engine pondering. Turning this off
+might be better for interactive use in some interfaces.
+
+=item B<KibitzMove> (default: false)
+
+Whether to kibitz when playing a move.
+
+=item B<KibitzPV> (default: false)
+
+Whether to kibitz when the PV is changed (new iteration or new best move).
+
+=item B<KibitzCommand> (default: "tellall")
+
+xboard command to use for kibitzing, normally "tellall" for kibitzing
+or "tellothers" for whispering.
+
+
+=item B<KibitzDelay> (default: 5)
+
+How many seconds to wait before starting kibitzing. This has an
+effect only if "KibitzPV" is selected, move kibitzes are always sent
+regardless of the delay.
+
+=item B<UCI> (default: false)
+
+If true PolyGlot will not understand xboard commands.
+
+=item B<Book> (default: false)
+
+Indicates whether a PolyGlot book should be used. This has no effect
+on the engine own book (which can be controlled with the UCI option
+"OwnBook" in the [Engine] section). In particular, it is possible to
+use both a PolyGlot book and an engine book. In that case, the engine
+book will be used whenever PolyGlot is out of book. Remember that
+PolyGlot is unaware of whether the engine is itself using a book or
+not.
+
+=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.
+
+=item B<BookFile> (default: book.bin)
+
+The name of the (binary) book file. Note that PolyGlot will look for
+it in the directory it was launched from, not in the engine directory.
+Of course, full path can be used in which case the current directory
+does not matter.
+
+NOTE: When using PolyGlot with a UCI GUI this parameter can be set
+via the UCI option "Polyglot BookFile".
+
+=item B<BookRandom> (default: true)
+
+Select moves according to their weights in the book. If false the move
+with the highest weight is selected.
+
+=item B<BookLearn> (default: false)
+
+Record learning information in the opening book. Naturally this requires
+the opening book to be writable.
+
+=item B<UseNice> (default: false)
+
+Run the engine at nice level 5, or "NiceValue" if it set. On some
+operating systems it may be necessary to run the engine at lower
+priority for it to be responsive to commands from PolyGlot while
+searching.
+
+=item B<NiceValue> (default: 5)
+
+Nice levels go from -20 to 20 with 20 being the lowest priority.
+On Unix only root can set negative nice levels. On Windows the standard
+Win32 priority levels are mapped in a sensible way to Unix nice levels.
+
+
+=item B<Affinity> (default: -1)
+
+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.
+
+
+=back
+
+=head2 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.
+
+IMPORTANT: Any of these work arounds might be removed in future
+versions of PolyGlot. You are strongly recommended to contact the
+author of faulty software and truly fix the problem.
+
+PolyGlot supports the following work arounds:
+
+=over 4
+
+=item B<UCIVersion> (default: 2)
+
+The default value of 2 corresponds to UCI+. Use 1 to select plain
+UCI for engines that have problems with UCI+.
+
+=item B<CanPonder> (default: false)
+
+PolyGlot now conforms to the documented UCI behaviour: the engine will
+be allowed to ponder only if it (the engine) declares the "Ponder" UCI
+option. However some engines which can actually ponder do not declare
+the option. This work around lets PolyGlot know that they can ponder.
+
+=item B<SyncStop> (default: false)
+
+When a ponder miss occurs, Polyglot interrupts the engine and
+IMMEDIATELY launches a new search. While there should be no problem
+with this, some engines seem confused and corrupt their search board.
+"SyncStop" forces PolyGlot to wait for the (now useless) ponder search
+to finish before launching the new search.
+
+=item B<PromoteWorkAround> (default: false)
+
+Some engines do not specify a promotion piece, e.g. they send "e7e8"
+instead of the correct "e7e8q". This work around enables the
+incorrect form (and of course promotes into a queen).
+
+=item B<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.
+
+
+=back
+
+
+=head2 [Engine] section
+
+This section contains engine UCI options. PolyGlot does not
+understand them, but sends the information to the engine at startup
+(converted to UCI form). You can add any UCI option that makes sense
+to the engine (not just the common options about hash-table size and
+tablebases).
+
+NOTE: use INI syntax, not UCI. For example "OwnBook = true" is
+correct. It will be replaced by PolyGlot with "setoption name OwnBook
+value true" at engine startup.
+
+Standard UCI options are
+
+ Hash
+ NalimovPath
+ NalimovCache
+ OwnBook
+
+Hidden options like "Ponder" or "UCI_xxx" are automatic
+and should not be put in an INI file.
+
+The other options are engine-specific. Check their name using a UCI
+GUI or launch the engine in a console and type "uci".
+
+=head1 EXAMPLES
+
+Compile "games.pgn" into a book "book.bin" retaining all lines of at
+most 30 plies.
+
+ polyglot make-book -pgn games.pgn -bin book.bin -max-ply 30
+
+Merge books "in1.bin" and "in2.bin" into a book "out.bin".
+
+ polyglot merge-book -in1 w1.bin -in2 w2.bin -out w.bin
+
+
+Here is a minimal config file
+
+ [PolyGlot]
+ EngineCommand = fruit
+ [Engine]
+
+
+=head1 EXIT STATUS
+
+PolyGlot always returns 0 on exit.
