+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.

+<h2>Change History</h2>
+<ul>
+    <li>10th August 2022: Bug fix with -z for failure to match the final position and not
+    necessarily marking the first match in a game when there are multiple matches.
+
+    <li>7th August 2022: Bug fix for -z when only one side's pieces are listed.
+
+    <li>27th June 2022: --firstgame and --gamelimit added. Suggested by Peter Stein.
+
+    <li>23rd June 2022: Regular expressions added to tag matching via -t. Suggested by Peter
+    Stein.
+
+    <li>18th May 2022: --seventyfive added.
+
+    <li>17th May 2022: --repetition5 added.
+
+    <li>16th May 2022: Multiple numeric matches of a single tag with -t now
+    require all matches to be true. This allows selection of ranges of values
+    via &lt; and &gt; operators, for instance.
+    Floating-point numerical values are accepted.
+
+    <li>3rd May 2022: Bug fix for failure to clear a pointer to freed memory.
+
+    <li>27th Mar 2022: Relational operator (>, <, etc.) may be used to match
+    any wholly numeric tag values via the -t flag.
+
+    <li>23rd Feb 2022: Bug fix for material matches where games involve promotion.
+
+    <li>17th Feb 2022: Added recognition of some en passant indicators in the input. They are deleted
+    in the output version.
+
+    <li>26th Jan 2022: Added recognition of single-line comments. I have no idea why these escaped my
+    attention over the past 27 years!
+    <br>Fixed inconsistent conversion of polyglot hashcodes shorter than 16 digits, and output hashcodes
+    with leading zeros where appropriate. The fix affected correct operation of the -H option.
+    <br>Replaced nonsense Result tags with *.
+    <br>Fixed incorrect TotalPlyCount when --totalplycount and --splitvariants are used together.
+    <br>Thanks for Robert Gamble for highlighting these issues.
+
+    <li>18th Jan 2022: Bug fix to --evaluation that counted illegal ep moves in the Shannon evaluation.
+
+    <li>28 Dec 2021: Edits to the index to make it a little more structured.
+
+    <li>24th Nov 2021: Added -Wfen.
+
+    <li>16th July 2021: Added --deletesamesetup.
+
+    <li>25th June 2021: Extended matching of TimeControl to include the formats
+    of sudden death and sandclock.
+
+    <li>19th June 2021: Added --addfencastling following a suggestion from
+    David Barlow.
+
+    <li>4th Apr 2021: Added --detag following a suggestion by Gabriele Battaglia.
+
+    <li>2nd Mar 2021: Make duplicate suppression work with input from stdin. Added --minply, --maxply,
+    --minmoves, --maxmoves as clearer alternatives to -p and -b.
+
+    <li>27th Jan 2021: Bug fix to --fixtagstrings.
+
+    <li>3rd Jan 2021: Added --linenumbers following a suggestion by Ejner Borgbjerg.
+
+    <li>8th Nov 2020: Added --fixtagstrings.
+
+    <li>7th Nov 2020: Date matches with -t and -T extended to match on month and day as well as year.
+
+    <li>7th Oct 2020: Added --wtm and --btm.
+
+    <li>25th Jul 2020: Added limited relational TimeControl matching with -t following
+    a suggestion by Erwin Wouterson.
+
+    <li>2nd Jul 2020: Added missing 'ep' for en passant moves with -Wxlalg and -Wxolalg.
+
+    <li>12th Feb 2020: Bug fix to eliminate illegal pawn moves in long algebraic notation.
+
+    <li>13th Oct 2019: Suppressed repeated error message with malformed dates when matching a Date tag with a relational operator.
+
+    <li>31st Jul 2019: Added --startply.
+
+    <li>21st Jun 2019: Added --fenpattern, --fenpatterni, --materialy and --materialz as command-line arguments.
+
+    <li>9th May 2019: Delete NAGs appearing before the first move of a game. $220 is
+    sometimes used (e.g., by ChessPad) as a print-board indicator.
+
+    <li>22nd Apr 2019: Improved --repetition so that it does not give false positives when
+    castling rights or who is to move are different.
+    <p>Retain next move number rather than resetting to 1 with --dropply and --dropbefore.
+
+    <li>14th Apr 2019: Fixed a memory error in v18-10 that occurred when a positional match was found but the moves of the game were invalid.
+
+    <li>28th Mar 2019: Added --xroster to suppress tags that are not required with -R.
+
+    <li>13th Nov 2018: Missing SetUp tags no longer elicit an error message as this contravention of the standard is so common.
+
+    <li>28th Oct 2018: Negative value accepted with --dropply to indicates plies to be
+    retained at the end of the game.
+
+    <li>18th Oct 2018: open game files in binary mode to cope with the Ctrl
+    characters that appear in some.
+
+    <li>17th Oct 2018: Accept Z0 as an alternative to --.</li>
+
+    <li>13th Oct 2018: Added --dropbefore as a result of a suggestion by Josip Salai.
+    Fixed missing SetUp tag with --dropply.
+    Fixed -H to work with 32-bit Windows.</li>
+
+    <li>7th Oct 2018: Added -y.</li>
+
+    <li>19th Aug 2018: Fixed a memory leak with -z.</li>
+
+    <li>11th July 2018: Added the MatchLabel tag and FENPatternI matching
+    with -t after a suggestion by Hedinn Steingrimsson.
+    In addition, significantly improved the efficiency of FENPattern
+    matches.</li>
+
+    <li>3rd July 2018: Added the MaterialMatch tag with -z after a suggestion
+    by Hedinn Steingrimsson.</li>
+
+    <li>23rd Apr 2018: With -R, include tags in the output that are not explicitly
+    listed in the roster order. This aligns the behaviour with the documentation.</li>
+
+    <li>9th Feb 2018: Suppress warning for null moves when --allownullmoves is used.
+        With --fixresulttags, prefer the terminating result if either it or the result
+        tag is "*".</li>
+
+    <li>29th Dec 2017: Corrected failure to OR rather than AND the pseudo Elo
+    tag used with -t.</li>
+
+    <li>17th Dec 2017: Accepted multiple NAG comment pairs after a move.
+    If NAGs are suppressed then the associated comments are retained.</li>
+        
+    <li>30th Nov 2017: Added --nestedcomments.</li>
+        
+    <li>12th Nov 2017: Added --dropply after a suggestion by Heiko Bruns.</li>
+        
+    <li>5th Oct 2017: Only require "960" in Variant tag strings for
+    Chess960 games.</li>
+
+    <li>23rd Sep 2017: Added the previously documented, but
+    unimplemented --underpromotion.</li>
+
+    <li>3rd Sep 2017: Bug fix for zero-move games which were not being
+    followed by a blank line.</li>
+    
+    <li>26th July 2017: --matchplylimit added following a suggestion by James Ward.</li>
+
+    <li>23rd July 2017: Bug fix for --splitvariants.</li>
+
+    <li>21st July 2017: Added --nobadresults to suppress games with inconsistent
+    result indications.
+
+    Fixed failure to correct terminating result with --fixresulttags.
+
+    Added --allownullmoves.</li>
+
+    <li>15th July 2017: Added -Tf for FEN pattern matching.</li>
+
+    <li>8th July 2017: Added --plycount. With -z, use a FEN tag (if present) to count
+    the number of pieces.</li>
+
+    <li>6th July 2017: Adjusted -z to work correctly with a position stability value of 0.
+    Implemented the suggestion of Josip Salai that that FEN as the marker with --markmatches
+    should be interpreted as a request to output the FEN encoding of the match position.</li>
+
+    <li>28th June 2017: Added a c1 comment to -Wepd output to record the game's result.
+    Added the requirement that the Variant tag contain the string "chess 960" to be
+    considered as Chess960 games on output. This primarily affects encoding of castling
+    moves in long-algebraic notation.</li>
+
+    <li>6th June 2017: Added a second number to the -# flag to control file numbering.</li>
+        
+    <li>4th June 2017: Chess960 long algebraic castling notation accommodated
+    on both input and output. This is where castling is indicated by specifying
+    the Rook's column as the destination for the King.</li>
+
+    <li>2nd June 2017: With --fixresulttags don't report inconsistent results that
+    can be fixed.</li>
+
+    <li>21st May 2017: Added --commentlines after a suggestion
+    by Gabriele Battaglia.</li>
+
+    <li>21st April 2017: Optional limiting depth added to --splitvariants.</li>
+
+    <li>7th April 2017: License updated to version 3 of the GPL.</li>
+        
+    <li>31st March 2017: Added --splitvariants after a suggestion by Vladimir Volovich
+    to add functionality found in pgnsplit.</li>
+
+    <li>19th February 2017: Extended --selectonly and added --skipmatching after
+        a suggestion by Folkert van Heusden.</li>
+
+    <li>16th February 2017: Fixed runtime failure when -x and -n were used together.
+    Added missing SetUp tag when a FEN tag is present.
+    Correct "1/2" in a Result tag to "1/2-1/2".
+    Added explicit Q promotion when unspecified.
+    Fixed lack of output with -W (i.e., output as source).</li>
+
+    <li>29th January 2017: Added --hashcomments to add a comment containing 
+        a polyglot hash code after each move. Added -H for Zobrist polyglot hash
+        matches.</li>
+        
+    <li>Added text after -F for FEN-position output at arbitrary positions and not simply
+    at the end of a game. Suggested by Josip Salai.</li>
+    
+    <li>22nd January 2017: Added --stopafter.</li>
+        
+    <li>20th January 2017: Added --nosetuptags and --onlysetuptags following a 
+        discussion with Mike Crockett. Added -p[elu] for finer control of game
+        length matching than provided by -b.</li>
+        
+    <li>14th January 2017: Fixed --fuzzydepth.</li>
+        
+    <li>9th January 2017: Improved the efficiency of (lack of) stalemate detection.</li>

+        <li>FEN tags with the -t flag are used as positional matches
+        (equivalent to -x matches).
+        <li>Non-standard tags are now retained in game output.
+      </ul></li>
+
+    <li>12th January 2000
+    C compiler with Red Hat Linux 6 was no longer happy with

+    Added a little more error recovery.</li>
+
+    <li>15th November 1996
+    Added -Z.</li>
+
+    <li>23rd Sep 1996
+    It is no longer necessary to omit move numbers from the variations
+    files (-v and -x). This makes it easier to cut and paste games
+    of interest into these files.</li>
+
+    <li>28th Jun 1996
+    It is no longer necessary to terminate the tag file (-t).
+    Relational operators added in the tag file (-t).
+    Added -E flag.</li>
+
+    <li>7th May 1996
+    Corrected failure to make ECO classification when combined with -x.

+      <ul>
+        <li>Added ECO classification with -e.

+        variation move Nc6 is now no longer matched by game move c6.
+      </ul></li>
+
+    <li>22nd Mar 1995:
+    Made permutation matching with -v the default and added -P
+    to suppress it.</li>

+    earlier unreleased version.
+        <li>Added -d flag.
+      </ul></li>
+
+    <li>8th Jul 1994:
+      <ul>
+        <li>Added -o flag.
+        <li>Discarded writing to standard output in DOS version because of
+        extensive problems trying to make this work with redirected

+<h2>Overview</h2>
+<p>This page documents the free, open-source program 
+    <a href="https://www.cs.kent.ac.uk/~djb/pgn-extract">pgn-extract</a>, 
+    which is a <em>command-line</em> program for searching, manipulating and formatting
+chess games recorded in the Portable Game Notation (PGN) or something close. It
+is capable of handling files containing millions of games.
+It also recognises Chess960 encodings.
+<p>There are several ways to specify the criteria on
+which to extract; for instance: textual move sequences, the position reached after a
+sequence of moves, information in the tag fields, and material balance
+in the ending.
+Full ANSI C source and a 32-bit Windows binary for the program are available
+under the terms of the <a href="#license">GNU General Public License</a>.
+The program includes a semantic analyser which will
+report errors in game scores and it is also able to detect duplicate
+games found in one or more of its input files.
+
+<p>The range of input move formats accepted is fairly wide and includes
+recognition of lower-case piece letters for English and upper-case
+piece letters for Dutch and German.
+The default output is in English Standard
+Algebraic Notation (SAN), although there is some support for output
+in different notations.
+
+<p>Extracted games may be written out either including or excluding
+comments, NAGs, and variations. Games may be given ECO classifications
+derived from the accompanying file eco.pgn, or a customised version
+provided by the user.
+
+<p>Plus, lots of other useful features that have gradually found their
+way into what was once a relatively simple program!
+
+<h2>Getting-started video for Windows users</h2>
+<p>For Windows users who are really only interested in getting
+the binary working, there is <a href="https://www.cs.kent.ac.uk/~djb/pgn-extract/intro.mp4">a short introductory video</a>.

+However, you are strongly advised to read the remainder
+of this page before attempting to use pgn-extract in earnest.
+<ul>
+      <li>-7 - output only the seven tag roster for each game. Other tags (apart
+            from FEN and possibly ECO/Opening/Variation) are discarded
+	    (See <a href="#-e">-e</a>).

+
+<h2 id="usage">Usage and flags/command-line arguments</h2>
+<p>pgn-extract takes an arbitrary number of game scores as input and outputs
+zero or more of these games, typically in English Standard Algebraic
+Notation (SAN). Which of the input games are output, and the style
+of the output, depend upon the particular set of command line flags
+passed to pgn-extract.
+The general form for calling pgn-extract is as follows:
+<pre>
+pgn-extract [flags] [input-game-files]
+</pre>
+
+<p>In its simplest form, calling pgn-extract with no arguments will cause
+it to read games from its standard input, check them and reproduce those
+without errors in SAN notation on its standard output.
+
+<h2 id="input">Game input format</h2>
+<p>This program's principle aim is to be able to read PGN files and output
+games of interest. It follows that the input should look reasonably like PGN to
+start with but it does not require the move text be in
+Standard Algebraic Notation (SAN).  It will accept quite a few common
+formats including:
+<ul>
+    <li>Algebraic
+    <li>Long Algebraic
+    <li>various commonly-used intervening characters, such as : - x
+    <li>Dutch and German upper case piece letters.
+    (Support for Russian piece letters is in prototype.)
+    <li> lower-case English piece characters (except that it will always prefer
+    'b' to mean a pawn move rather than a Bishop move).
+</ul>
+<p>It does not
+require that there be any move numbers or PGN headers preceding a game,
+as long as the move text is terminated by a valid result designation:
+*, 1-0, 0-1, 1/2-1/2 (1/2 is also accepted).
+This makes the program reasonably suitable for entering raw game text and
+having it reformatted in proper SAN with a full set of headers.
+
+<h2 id="-f">File of PGN files (-f)</h2>
+<p>Normally, the input files from which games are to be extracted are listed on the
+command line:
+<pre>
+pgn-extract file1.pgn [file2.pgn ...]
+</pre>
+
+<p>An alternative to listing the game files on the command line is to list
+their names, one per line, in a file which is then given after the -f flag:
+<pre>
+pgn-extract -ffile_list
+</pre>
+
+<p>In order to save the output in a file rather than standard output,
+use <a href="#output">-o, --output, -a, --append</a> to indicate the output
+file name, for instance:
+<pre>
+pgn-extract -oall.pgn file1.pgn file2.pgn file3.pgn
+pgn-extract --output all.pgn file1.pgn file2.pgn file3.pgn
+</pre>
+
+<p>While pgn-extract can be used simply to check and reformat all the input games,
+it is more usual to use it to select subsets of the input games.
+Several different criteria are available on
+which to extract: <a href="#variations">move variations</a>,
+<a href="#-t">information in the tag fields</a>, and
+<a href="#-z">material balance in the ending</a>, for instance.
+All of these criteria are described in detail below.
+
+<h2 id="output">Output files (-o, --output, -a, --append)</h2>
+<p>In order to output all matched games to a single new file, the -o flag is used:
+<pre>
+pgn-extract -onew.pgn file1.pgn file2.pgn
+</pre>
+<p>This has the effect of creating new.pgn from the contents of file1.pgn
+and file2.pgn.
+The games
+in both source files are checked and rewritten, if necessary, into SAN.
+Any previous contents of new.pgn will be lost with the -o flag. In order to
+avoid this and append to an existing file, use the -a flag:
+<pre>
+pgn-extract -anew.pgn file1.pgn file2.pgn
+</pre>
+<p>Note that there must be no space between either -o or -a and the output file name.
+
+<p>The long-form --output and --append are provided as alternatives to -o and -a,
+respectively. In these cases, there must be a space between the
+flag and the output filename. For instance:
+<pre>
+pgn-extract --output new.pgn file1.pgn file2.pgn
+pgn-extract --append new.pgn file1.pgn file2.pgn
+</pre>
+
+<h2 id="-r">Check for errors (-r)</h2>
+<p>Check the input files for errors but do not output any matched games.
+Useful for cleaning up files of games before proper processing.
+<pre>
+pgn-extract -r file.pgn
+</pre>
+<p>Useful with -s (silent mode) for checking a big file of games without
+having progress reported and just seeing the errors.
+
+<h2 id="keepbroken">Retaining games with errors</h2>
+<p>Normally, pgn-extract reports games with errors but does not output them.
+Games with errors may be output with the --keepbroken argument.
+The errors are still reported but the
+moves from the point where the error was detected onwards are placed in a comment rather
+than being retained as part of the game.
+
+<h2 id="allownullmoves">Allow NULL moves in the main line (--allownullmoves)</h2>
+<p>Null moves (--) are not normally allowed in the main line. The --allownullmoves 
+option retains games that include them and does not issue a warning.
+
+<h2 id="-l">Log files (-l, -L)</h2>
+<p>Error messages and verbose reporting is done to the standard error
+output unless the -l or -L flag is used.
+Both are immediately followed by the name of a file to which a log
+should be written.
+The -l flag creates a new log file, while -L appends to an existing log file:
+<pre>
+pgn-extract -llog.txt file.pgn
+pgn-extract -Llog.txt file.pgn
+</pre>
+<p>This option is useful in combination with <a href="#-r">-r</a> (report)
+to generate diagnostic information without outputting games while game
+data is being checked and cleaned.
+<p>A log file will contain only error reports if the <a href="#-s">-s</a> 
+(silent) flag is used.
+
+<h2 id="variations">Variations (-v, -x and -P)</h2>
+<p>There are two distinct ways to specify variations of interest;
+positional variations (the <a href="#-x">-x</a> flag) and
+textual variations (the <a href="#-v">-v</a> flag).
+The major difference between the two is that positional variations
+specify a complete move sequence whose end position is the primary
+point of interest, whereas textual variations allow incomplete and
+fuzzy move sequence matches on the text of a game to select games.
+Whilst it is possible to use both
+flags together, this would be unusual as a game must match with both to
+be extracted.
+
+<ul>
+<li id="-x"><p>Positional Variations (-x)<br />
+<p>The variations in which you are interested should be placed in a file
+whose name is supplied with the -x flag. For instance:
+<pre>
+pgn-extract -xvars
+</pre>
+<p>where each variation is
+listed on a single line in the file vars (the filename is immaterial).
+The following set of moves:
+<pre>
+e4 c5 Nf3 d6 d4 cxd4 Nxd4 Nf6 Nc3 a6
+</pre>
+<p>indicates that you wish to pick up all games reaching the Najdorf
+variation position of the Sicilian Defence.
+Games reaching the end position of this sequence are
+selected regardless of the route that was taken to reach it.  This
+allows various transpositional sequences to be specified by quoting
+just one line to reach the required point.  Therefore, games employing
+the following move order will be picked up by quoting the line above.
+<pre>
+e4 c5 Nc3 d6 Nge2 Nf6 d4 cxd4 Nxd4 a6
+</pre>
+<p>A position is considered to match a required variation if it generates
+the same board hash value. In the interests of reasonable efficiency,
+no attempt is made to actually examine the state
+of the board. There is, therefore, the potential for false hits but in
+my usage of pgn-extract I have not found this to be a problem.
+
+<p>With this option, games are only searched to a depth approximately equal
+to the length of the longest positional variation, in order to make
+processing of large data sets faster than with a search of the whole
+game.
+
+<p>A comment line may be placed in a variation file by using a '%' as the
+first character of the line. Move numbers are optional within the
+list of moves.
+
+<p>Positional matches are also available using a FEN description of the
+desired position.
+See the description of the <a href="#-t">-t flag</a>
+for how to specify a FEN position,
+and <a href="#-F">the -F flag</a>
+for a simple way to generate a FEN description from
+a game score.
+
+<li id="-H"><p>Polyglot hashcode matches (-H)<br />
+Positional matches are available by using a polyglot hashcode to specify
+the desired position.
+The hashcode immediately follows the -H, for instance:
+<pre>
+pgn-extract -H19b4aea499e0ba7c --markmatches match games.pgn
+</pre>
+See <a href="#hashcomments">--hashcomments</a> for how
+to generate polyglot hashes.
+
+<li id="-v"><p>Textual Variations (-v) <br />
+<p>With this option, the matching is purely textual in nature,
+in contrast to the <a href="#-x">-x</a> flag.  The -v flag works by
+string matching on the input text of moves,
+so there is no facility for picking up transpositions automatically.
+The variations in which you are interested should be placed in a file
+whose name is supplied with the -v flag. For instance:
+<pre>
+pgn-extract -vvars
+</pre>
+<p>Each variation should be listed on a single line
+in the file vars (the filename is immaterial).
+The move sequence:
+<pre>
+e4 c5 Nf3 d6 d4 cxd4 Nxd4 Nf6 Nc3 a6
+</pre>
+<p>indicates that you wish to pick up all games following the normal move
+order of the Najdorf variation of the Sicilian Defence, and
+<pre>
+d4 Nf6 c4 e6 Nc3 Bb4
+</pre>
+<p>that you are interested in Nimzo-Indian games.
+The order in which the moves are played by either White or Black
+is immaterial. All combinations are tried, so the ordering:
+<pre>
+c4 e6 Nc3 Bb4 d4 Nf6
+</pre>
+<p>will produce the same set of matches as the previous ordering of the
+Nimzo-Indian moves (see <a href="#-P">the -P flag</a> for how
+to prevent this).
+
+<p>A comment line may be placed in a variation file by using a '%' as the
+first character of the line. Move numbers are optional within the
+list of moves.
+
+<p>As transpositions are not picked up automatically with this flag,
+if you also wanted to
+recognise the following as a Najdorf, you would have to add this line
+to the variations file in addition to that given above:
+<pre>
+e4 c5 Nc3 d6 Nge2 Nf6 d4 cxd4 Nxd4 a6
+</pre>
+<p>However, because of the way in which the matching is done, it is
+possible to specify slight alternatives on the way in which individual
+moves are written.  Notational alternatives for a single move are just
+written separated from each other with a non-move character.  This
+variation specifies both the shorter and longer ways of writing the
+captures in a Najdorf:
+<pre>
+e4 c5 Nf3 d6 d4 cxd4|cd Nxd4|Nd4 Nf6 Nc3 a6
+</pre>
+<p>However, given the variety of possible ways of writing various moves in
+non-SAN format, e.g.
+<pre>
+cxd4|cd|c5d4|c5-d4
+</pre>
+<p>variation lists can get quite messy and I believe that this approach is
+best avoided by ensuring that the input is proper SAN and only using
+SAN notation in the variations file. In this way, the alternative-separator
+can then be used purely for indicating genuine alternative moves at
+that point, e.g.
+<pre>
+e4 c5 Nf3 d6 d4|d3
+</pre>
+<p>An important point when listing moves is that check and mate indicators
+should be included where appropriate, otherwise moves incorporating
+these characters in games to be searched will fail to match.
+
+<p>There is little point in using the -v flag in preference to
+the <a href="#-x">-x</a> flag
+if you are only interested in finding games that reach a particular
+position.  The real use for -v is when you wish to pick up games
+in a more general way.  For instance, the character '*' may be used in
+place of any move to indicate that you don't care what was played at
+that point.  So the following:
+<pre>
+* b6
+</pre>
+<p>means that you are interested in all games in which Black replied
+1 ... b6 regardless of White's first move.
+The sequence:
+<pre>
+d4 * c4 * Nc3 *
+</pre>
+<p>will pick up Nimzo-Indian, Grunfeld, King's Indian, etc. defences.
+This notation is not possible with <a href="#-x">positional variations</a>.
+
+<p>In addition, the character '!' may be used in front of any move to
+indicate that you wish to disallow particular moves from matching at
+this point.  For instance, if you want to find Sicilian games where
+White did not reply with Nf3 at move 2 you would specify:
+<pre>
+e4 c5 !Nf3
+</pre>
+<p>If you wished to disallow 2.Ne2 as well then
+<pre>
+e4 c5 !Nf3|Ne2
+</pre>
+<p>does the job.  (Adding parentheses makes no difference as the '!' is
+applied to all of the following move string.)
+
+<p>Care should be taken combining '!', '*' and variation permutations (see <a
+href="#-P">the -P flag</a>).
+Disallowed moves take precedence over '*' moves.  If a single
+disallowed move is found in a game within the length of the variation,
+that game is excluded.  This was the most sensible interpretation that
+I could find to place on this usage.
+
+<li id="-P"><p>Textual Variation Permutations (-P)<br />
+<p>Normally, all permutations of a textual variation (see <a href=
+"#-v">the -v flag</a>) are tried against the
+moves of a game.  This cuts down on the number of separate
+transpositional orderings that it is necessary to list, at the cost of
+slower matching of each game.  If the following were used to look for
+Nimzo-Indian games:
+<pre>
+d4 Nf6 c4 e6 Nf6 Nc3 Bb4
+</pre>
+<p>a side-effect would be that it will also pick up games which start as:
+<pre>
+1. c4 Nf6 2. Nc3 e6 3. d4 Bb4
+</pre>
+<p>for instance.
+The -P flag requests that textual variations are matched against the
+moves of the game strictly in the order in which they are listed,
+without trying different orders.  So, if you want to find only those
+games that follow a particular move order, use this flag to suppress
+permutations.
+</ul>
+
+<h2 id="matchplylimit">Limit the ply depth to which matches are sought</h2>
+<p>The --matchplylimit option limits the number of ply to which matches are sought.
+This allows hashcode (<a href="#-H">-H</a>) and FENPattern matches
+(<a href="#FENPattern-t">-Tf</a>) to be
+limited to the start of a game, for instance.
+For instance:
+<pre>
+pgn-extract -Hcdd6cd2d4e4045e --matchplylimit 12 games.pgn
+</pre>
+<p>would search a maximum of 12 ply in each game for a position corresponding
+to the specified hashcode.
+<p>Note that usage of the <a href="#-x">-x</a> flag also limits the search depth.
+
+<h2 id="startply">Only start matching after N ply (N &gt;= 1)</h2>
+<p>The --startply argument defers match attempts until the move at the given ply is played.
+A value of 1 would start matching from the first move of the game, whereas a value of 3 would
+only attempt matches after both players had played their first moves.
+
+<h2 id="duplicates">Duplicate games (-d, --duplicates and -D or --noduplicates, --deletesamesetup, plus -Z)</h2>
+<p>If either the -d, --duplicates or -D flag is used, pgn-extract
+attempts to recognise duplicate extracted games.
+Using the -d or --duplicates flag indicates that you wish copies of the
+duplicate
+games to be written to the indicated file:
+<pre>
+pgn-extract -ddupes.pgn -ounique.pgn file.pgn
+pgn-extract --duplicates dupes.pgn --output unique.pgn file.pgn
+</pre>
+<p>will both extract from file.pgn the unique set of games into unique.pgn and
+the duplicates (i.e., the second and subsequent copies of a game)
+to dupes.pgn.
+A comment identifying in which file a
+duplicate was found precedes the first duplicate found in that file and
+each duplicate game has a prefix comment indicating the file in which
+the first version was found.
+Note that there must be no space between <code>-d</code> and the filename
+but a space between if <code>--duplicates</code> is used.
+
+<p>With the -D flag duplicate games are suppressed
+from the output. These two flags are mutually exclusive, therefore.
+
+<p>Duplicates are identified by comparing a hash value for the board of
+the end positions of extracted games and an additional cumulative hash
+value generated from the move sequence.
+If these both values match then games are considered to be
+duplicates.
+This is not guaranteed to be exact but it gives a good approximation.
+If the position of the pieces is important but the move sequence is not then use
+<a href="#fuzzydepth">--fuzzydepth</a>.
+
+<p>You should note that games are only considered to be duplicates on the
+basis of the moves played.  It may be that a game considered to be a
+duplicate contains annotations and variations not present in the one
+found earlier, so it might be necessary to do some swapping around to
+obtain those you really wish to retain. You should, therefore, use the
+-D flag with caution if you are trying to reorganise your master
+collection rather than selecting out specific games for examination.
+(See also <a href="#-U">the -U flag</a>.)
+
+<p>Detecting duplicates requires memory for the storage of a hash table
+containing information on each game.
+Large databases can result in a MallocOrDie error.
+If this is the case, try using the -Z flag which
+forces pgn-extract to store its hash table externally, in a file called
+virtual.tmp. Each game requires 16 bytes of file space. Clearly, if a
+very large database is being processed, there is a risk of filling up
+the available file space if there is insufficient available.
+
+<p>The --deletesamesetup option examines the starting position of games and
+suppresses those with the same starting position as games already seen,
+regardless of the games' moves.
+This is intended to filter files containing games with SetUp/FEN tags in order to
+isolate the unique starting positions.
+If applied to a file of games all starting from the standard game setup, only the first
+game would be retained.
+
+<h2 id="fuzzydepth">Positional duplicates match</h2>
+<p>This flag allows a match on the basis of board position at the
+indicated number of plies or the end of the game.
+The flag is followed by the ply depth at which matches are to be
+considered. The value 0 is used to request matching at the end of
+games. It should always be used in combination with at least
+one of: <a href="#duplicates">-d/--duplicates, -D/--noduplicates</a>, <a href="#-U">-U</a>.
+
+<p>In contrast to the <a href="#duplicates">--duplicates</a> matching,
+the match does not consider the move sequence used to reach the
+match position.
+
+<p>For example:
+<pre>
+pgn-extract --fuzzydepth 40 -D games.pgn
+</pre>
+<p>would suppress from the output multiple copies of games reaching 
+identical board positions after 40 ply. Note that en-passant and castling
+rights are not checked.
+
+<p>The following example would suppress the unique games and
+store the games considered to be duplicate at their final
+position in dupes.pgn:
+<pre>
+pgn-extract --fuzzydepth 0 -U -ddupes.pgn games.pgn
+</pre>
+
+<h2 id="-U">Suppression of unique games (-U or --nounique)</h2>
+<p>The -U flag suppresses output of the first occurrence of a particular
+game.  This is useful when combined with <a href="#duplicates">the -d flag</a>
+as a means of
+identifying just those games that are duplicated in a list of multiple
+files.  As the duplicate games are commented with the file in which
+they were located, it then becomes possible to prune a set of files
+containing common games.  For instance, suppose oldfile.pgn contains a
+set of games without duplicates, and you wish to know which games in
+newfile.pgn already occur in oldfile.pgn:
+<pre>
+pgn-extract -U -ddupes.pgn oldfile.pgn newfile.pgn
+</pre>
+<p>will write to dupes.pgn the duplicate games so that you can go through
+newfile.pgn and remove them.  Of course, if you simply want to hold the
+combined set of unique games in a single file you would use something like:
+<pre>
+pgn-extract -D -onewset.pgn oldfile.pgn newfile.pgn
+</pre>
+<p>See <a href="#duplicates">Duplicate Games</a> for dealing
+with MallocOrDie errors.
+
+<h2 id="-c">Check files for duplicates (-c, --checkfile)</h2>
+<p>Check files contain games that are to be used in duplicate detection,
+but not to form part of the output. If the filename appended to the
+argument has a .pgn/.PGN suffix it is assumed to be a single file of
+games. If it does not have this suffix then it is assumed to be a file
+containing a list of the names of PGN game files, one per line, to be
+used as check files.
+
+<p>A typical use for this is to select new games of
+interest from a file that probably contains games that exist elsewhere.
+In the following example, we wish to select Nimzo-Indian games from
+newfile.pgn that don't already occur in the master file nimzo.pgn:
+<pre>
+pgn-extract -cnimzo.pgn -vnimzo.var -D -onewnimzo.pgn newfile.pgn
+</pre>
+<p>The games in nimzo.pgn act as the source for duplicate detection so
+duplicates of these will be suppressed (<a href="#duplicates">the -D flag</a>).
+Only those games from
+newfile.pgn that are not in nimzo.pgn will be output to newnimzo.pgn.
+Contrast this behaviour with the following, which would create a new
+master file of games from the combination of nimzo.pgn and
+newfile.pgn:
+<pre>
+pgn-extract -vnimzo.var -D -onewnimzo.pgn nimzo.pgn newfile.pgn
+</pre>
+
+<p>--checkfile is available as an alternative to -c and must be followed
+by a space before the filename, e.g.:
+<pre>
+pgn-extract --checkfile nimzo.pgn -vnimzo.var -D -onewnimzo.pgn newfile.pgn
+</pre>
+
+<h2 id="-t">Matching on tag criteria (-t)</h2>
+<li id="text-t"><p>Textual Tag Matching with -t<br />
+<p>There are two ways to specify that you wish to use information in the
+tag fields as extraction criteria: the -t flag and
+<a href="#-T">the -T flag</a>.  The -t flag takes a file name
+argument and is the preferred method because of its ease of use and
+greater flexibility. The -T flag has fewer options and tag-matching syntax
+does not fit well with command-line usage.
+<p>For most situations, use -t with a file of the criteria to be matched:
+<pre>
+pgn-extract -t tags games.pgn
+</pre>
+<p>where <code>tags</code> is an arbitrary file name - you can use whatever name you wish.
+In the file are listed tag name and value pairs
+corresponding to the extraction criteria you wish to use.
+For textual matching, each line of this file should be of the form:
+<pre>
+PGN-Tag-name Tag-string
+</pre>
+<p>for instance:
+<pre>
+White "Tal"
+</pre>
+<p>(note the need to include double quotes around the tag value).
+This requests that only those games where Tal had the White pieces are
+to be considered for extraction.
+
+<p>Tag matching may be either textual or numeric.
+Here we cover textual matching. For matching of numeric tags see <a href=#date-t">Date and Elo Matching</a>,
+<a href=#time-t">Time Control Matching</a> and <a href="#numeric-t">Numeric Tag Matching</a>.
+
+<p>By default, prefix matching on tag values is done so that a criterion should be a prefix
+of the complete Tag string.
+Thus,
+<pre>
+Player "Karpov"
+</pre>  
+<p>would match:
+<pre>
+[White "Karpov"]
+[White "Karpov, A"]
+[White "Karpov, An"]
+[White "Karpov, Alexander"]
+</pre>
+<p>but not
+<pre>
+[White "Anatoli Karpov"]
+</pre>
+<p id="tagsubstr">To match anywhere within a tag include the --tagsubstr flag in the program's arguments.
+In this case, a match for "Karpov" would now match
+<pre>
+[White "Anatoli Karpov"]
+</pre>
+
+<p>If you wish to limit the year in
+which those games were played you might list:
+<pre>
+White "Tal"
+Date "1962"
+</pre>
+<p>This is a purely textual prefix match rather than a numeric one.
+
+<p>Multiple pairs with the same tag name are or-ed together so:
+<pre>
+% Find games in the period 1960-1962.
+Date "1960"
+Date "1961"
+Date "1962"
+</pre>
+<p>will select all games whose Date tags start with the three listed years.
+Note from this example that comments may be included in the tag file by using an initial '%' character on a line..
+
+<p>In general, tags names that differ are and-ed together, so:
+<pre>
+White "Tal"
+Black "Fischer"
+Date "1962"
+Result "1-0"
+</pre>
+<p>selects only those games that Tal won with the White pieces against
+Fischer in 1962.
+
+<p>It is important to note that:
+<pre>
+White "Tal"
+Black "Tal"
+</pre>
+<p>does not find all games played by Tal, but only those that he played
+against himself.  In order to overcome this, the pseudo-tag Player
+may be used
+<pre>
+Player "Tal"
+Date "1962"
+</pre>
+<p>finds all games from 1962 in which Tal had either the White pieces or
+the Black.  In effect, the White and Black player lists are or-ed
+together rather than and-ed using this pseudo-tag.
+
+<p>See the <a href="#-S">-S</a> flag for a soundex facility with tag matching.
+
+<p>All tag criteria except ECO classification are checked before the moves
+of the game in the interests of efficiency (tag checking is relatively
+fast whereas positional checking of the game is not). Only once the
+game has been processed is it checked to see whether an ECO tag match
+has been requested.  The consequence of this is that using <a href="#-e">the
+-e flag</a>
+in combination with ECO tag criteria you can search for games in
+particular ECO lines without an ECO tag having been present in the
+input form.
+
+<li id="date-t"><p>Date and Elo Matching with -t<br />
+<p>From a <a href="#-t">-t tag file</a>,
+more complex matching of dates and Elo values may be performed by
+placing an operator between the tag name and the tag string to be
+matched.
+For date matches:
+<pre>
+Date &lt; "1962"
+</pre>
+<p>would only match games played before 1962. Month and day values may also be
+included for additional granularity; e.g.:
+<pre>
+Date &gt; "2020.03.31"
+</pre>
+<p>Elo matches use a similar syntax:
+<pre>
+WhiteElo &gt;= "2500"
+</pre>
+<p>only matches games where White is a strong player. Probably of more
+general use is another pseudo-tag that I have introduced purely for
+this purpose: Elo.
+<pre>
+Elo &gt;= "2500"
+</pre>
+<p>matches games in which either player has an Elo tag matching that
+relationship.
+The operators allowed are &gt;, &gt;=, &lt;, &lt;=, =, and &lt;&gt; (not
+equal to).
+
+<li id="time-t"><p>TimeControl Matching with -t<br />
+<p>The -t option also supports very limited relational matching of two formats of the
+TimeControl tag: <em>time+increment</em> and <em>moves+time</em>.
+In both cases it is the <em>time</em> value of the control that is compared
+against a numerical value.
+For instance,
+<pre>
+TimeControl &gt;= "3600"
+</pre>
+<p>would match games with a TimeControl tag in which the <em>time</em> value
+is greater-than or equal to 3600 seconds. 
+For instance,
+<pre>
+[TimeControl "4500+60"]
+</pre>
+<p>and
+<pre>
+[TimeControl "40/9000"]
+</pre>
+<p>The operators allowed are &gt;, &gt;=, &lt;, &lt;=, =, and &lt;&gt; (not equal to).
+<p>Only the first descriptor in a tag value is compared.
+</ul>
+
+<li id="numeric-t"><p>Numeric Tag Matching with -t<br />
+<p>Matching of tags with numeric values may be performed with -t and a file of tag criteria.
+All of the relational operators are available: &lt;, &lt;=, &gt;, &gt;=, = and &lt;&gt; (not equal to).
+In the tag file associated with -t flag the value to be compared against a tag value is
+inserted between the name of the tag and the value against which a game's value is to be compared.
+For instance, given a pseudo-tag Difficulty, the following would find all games in which
+the value of the Difficulty tag was greater-than or equal-to 3:
+<pre>
+Difficulty >= "3"
+</pre>
+<p>Note that quotes are required around the numeric value.
+
+<p>Multiple relational matches of a single tag are and-ed rather than
+or-ed. That means that games may be selected based on a range for a particular tag.
+For instance:
+<pre>
+Difficulty >= "3"
+Difficulty <= "6"
+</pre>
+<p>would find only games with Difficulty tag values of 3, 4, 5 or 6.
+
+<li id="regex-t"><p>Regular Expression Tag Matching with -t<br />
+<p>The operator <code>=~</code> may be used to compare a tag value with a <em>regular expression</em> (details to be added).
+For instance:
+<pre>
+White =~ "^F.*r$"
+</pre>
+would match all games in which the White tag starts with 'F' and ends with 'r'.
+
+<li id="fen-t"><p>FEN positional matches with -t<br />
+<p>Use of a FEN tag with the -t flag has
+a special meaning. Rather than using this to match FEN tags in 
+the header of a game, a FEN description is used to indicate a search
+for a positional match (similar to use of the <a href="#-x">-x</a> flag).
+If a FEN description is provided with the -t flag, the indicated
+position is searched for in each game processed, and only those
+games that reach the indicated position are output.
+A FEN tag-pair for the starting position would be described by:
+<pre>
+FEN "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1"
+</pre>
+<p>The position after the two moves e4 c5 would be:
+<pre>
+FEN "rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq c6 0 2"
+</pre>
+<p>However, note that it is only the board position that is relevant for the match.
+Castling rights are not considered in the determination of equality.
+<p>The <code>--btm</code> and <code>--wtm</code> flags can be used to constrain the match
+by whether it is 'black to move' or 'white to move'. Otherwise, the player to
+move information is ignored.
+<p>See details of <a href="#-F">the -F flag</a> for a simple way to generate a FEN
+description from a game score.
+
+<p id="FENPattern-t">There is a variation on use of a FEN with -t flag
+and <a href="#FEN-T">-Tf flag</a>..
+The pseudo tag FENPattern takes a FEN-like description of a board
+containing meta characters that allow a fuzzy board match.
+In addition to the standard FEN characters having their usual
+meaning (1, 2, ... 8, R, N, B, etc.), the following
+meta characters are used:
+
+<ul>
+  <li>? - match any square. The square may be occupied or unoccupied.
+  <li>! - match any occupied square. The square may be occupied by a piece of any type and colour.
+  <li>A - match a single White piece.
+  <li>a - match a single Black piece.
+<!-- <li>m - match anything that is not a pawn. Equivalent to <code>[^Pp]</code>. -->
+  <li>* - match zero or more squares, occupied or unoccupied.
+  <li>[<em>xyz</em>] - match any of <em>xyz</em>, where <em>xyz</em> represents
+  any of the English piece-letter names (KQRNBPkqrnbp) and is case-sensitive.
+  In addition, 'A' and 'a' (as defined above) are available.
+  For instance: [Qq] matches either a White or Black queen;
+  [BbNn] matches any White or Black bishop or knight;
+  [Ar] matches any White piece or a Black rook.
+  <li>[^<em>xyz</em>] If the first character inside the square brackets
+  is '^' then the match is inverted; i.e., match any piece that is <em>not</em>
+  listed. For instance, [^BbNn] matches any piece that is not
+  a White or Black bishop or knight.
+</ul>
+<p>Ranks within the pattern are separated with a '/' character, as usual,
+but there should be no characters other than the board position.
+<p>
+For instance:
+<pre>
+FENPattern "rnbqkbnr/*/*/*/*/*/*/RNBQKBNR"
+</pre>
+<p>would match any board in which at least every non-pawn piece is 
+on its starting square.
+<pre>
+FENPattern "?????rk?/?????aaa/*/*/*/8/P[BP]P*/??KR????"
+</pre>
+<p>would match a board in which Black has a Kingside castled position behind three
+Black pieces (not necessarily pawns),
+White has a Queenside castled position with
+either a White pawn or bishop on b2 and the third rank is empty.
+<p>The pattern may be optionally followed by arbitrary text to serve as a pattern
+    identification. If used with the <code>--addlabeltag</code> program argument then
+    a <code>MatchLabel</code> tag will be added to the game containing the corresponding label.
+    For instance:
+<pre>
+FENPattern "?????rk?/?????pbp/*p?/*/*/8/PPP*/??KR????" castled
+</pre>
+<p>would add the tag pair:
+<pre>
+[MatchLabel "castled"]
+</pre>
+<p>for a match against Black kingside castled behind a fianchetto and White queenside
+    castled.
+<p><code>FENPatternI</code> is a variation of <code>FENPattern</code> that will
+    attempt two possible matches of a pattern: as written and inverted to swap
+    the colours. This is useful if you are interested in finding games with structural
+    properties for either side. If the pattern has an associated label and 
+    <code>--addlabeltag</code> is used then a match of the inverted version of
+    the pattern will add the suffix 'I' to the label. For instance:
+<pre>
+FENPatternI "?????rk?/?????pbp/*p?/*/*/8/PPP*/??KR????" castled
+</pre>
+<p>would add the tag pair:
+<pre>
+[MatchLabel "castledI"]
+</pre>
+<p>if the inverted match finds a game in which White has castled kingside behind
+a fianchetto and Black has castled queenside.
+<p>See also <a href="#FEN-T">-Tf</a> for a simpler command-line version of FEN pattern matching.
+
+<li id="fenpattern"><p>--fenpattern and --fenpatterni: Match games reaching a position matching the associated FEN pattern<br />
+<p>The --fenpattern and --fenpatterni command-line arguments are followed by a single string containing
+a FEN pattern to be matched. These arguments may appear multiple times.
+See <a href="#FENPattern-t">-t with FENPattern</a> for details of the patterns.
+
+<h2 id="-T">Tag criteria on the command line (-T)</h2>
+<p>An alternative to the <a href="#-t">-t flag</a> is the
+-T flag, for use where command line arguments are
+more convenient - perhaps where pgn-extract is being invoked from another
+program.  The tag coverage is not as extensive as with a tag file, and
+the syntax is rather cumbersome.  It is used as follows: after the -T
+comes a single letter from the limited set [abdeprw] to select string
+prefixes of the tag fields of a game.  For instance:
+<ul>
+  <li>-TaAnnotator - Extract games Annotated by Annotator.
+  <li>-TbPlayer - Extract games where Player has the Black pieces.
+  <li>-TdDate   - Extract games played on Date.
+  <li>-TeEco - Extract games with ECO designation Eco.
+  <li>-TfFENPattern - Extract games matching the given FEN pattern.
+  <li>-ThHashCode - Extract games with HashCode designation HashCode.
+  <li>-TpPlayer - Extract games where Player has either colour.
+  <li>-TrResult - Extract games with result Result (1-0, 0-1 or 1/2).
+  <li>-TwPlayer - Extract games where Player has the White pieces.
+</ul>
+<p>For example,
+<pre>
+pgn-extract -TwTal -TbFischer file.pgn
+</pre>
+<p>would extract games from file.pgn in which Tal had the White pieces and
+Fischer the Black.
+
+<p>Criteria of the same tag type are or-ed together, so
+<pre>
+pgn-extract -Tr1-0 -Tr0-1 file.pgn
+</pre>
+<p>extracts only decisive games.
+
+<p>Criteria of different tag types are and-ed together so
+<pre>
+pgn-extract -TwTal -Td1962 -Tr1-0 file.pgn
+</pre>
+<p>would extract only those games in which Tal played with the White
+pieces in 1962 and won.
+
+<p>The ECO classification (see <a href="#-e">the -e flag</a>)
+is performed before attempting to match an ECO tag, so:
+<pre>
+pgn-extract -TeA01 -e file.pgn
+</pre>
+<p>will perform ECO classification on the input file and extract games
+with ECO classification A01 (Nimzo-Larsen attack), for instance.
+
+<ul>
+<li id="date-T"><p>Date Matching with -T<br />
+<p>A simple form of relational date matching is available.
+A date may be prefixed with either 'b' or 'a' in order
+to match games played either before or after the specified date. This
+assumes that the date is stored in the game's date tag string in the
+normal form: YYYY.MM.DD and the day or month/day values are optional.
+
+<p>So,
+<pre>
+pgn-extract -Tdb1962.01 file.pgn
+</pre>
+<p>will look for games played before 1st January 1962.
+A fuller capability is available in tag files with <a href="#-t">the -t flag</a>.
+
+<li id="FEN-T">FEN Pattern matches with -T<br />
+<p>The -Tf flag allows a form of position matching similar to that
+available with <a href="#FENPattern-t">-t with FENPattern</a>.
+A FEN board position will be used as a position to be matched.
+Note that castling rights and who is to move should not be included.
+The syntax of the pattern allows for wildcard character,
+<a href="#FENPattern-t">documented below</a>. For instance:
+<pre>
+pgn-extract -Tf"*/*/*/*/???PP???/*/*/*"
+</pre>
+<p>would match any position on which White occupies both e4 and d4
+with pawns, regardless of the position of anything else.
+Note that the use of wildcard characters will almost certainly require the use
+of double-quote characters around the FEN pattern to escape them
+from interpretation by the operating system's command-line interpreter.
+</ul>
+
+<h2 id="-A">Argument descriptions in a file (-A)</h2>
+<p>It can be inconvenient to repeatedly type long argument lists
+on the command line. The -A flag makes it possible to list
+arguments in a file, rather than on a command line.  Each
+argument line within the file must be immediately preceded by
+a ':' (colon) character. Consider selecting games by Tal from
+a file caro.pgn and writing them to talgames.pgn. Using
+command line arguments, this would have the following form:
+<pre>
+pgn-extract -TpTal -otalgames.pgn caro.pgn
+</pre>
+<p>We can do the same job placing the argument list in the file args:
+<pre>
+% Select games by Tal.
+:-TpTal
+% Where to output the matched games.
+:-otalgames.pgn
+</pre>
+<p>and the same selection made with:
+<pre>
+pgn-extract -Aargs caro.pgn
+</pre>
+<p>Note that comments may be included using a '%' character.
+
+<p>Each argument should be listed on its own line, and all the
+arguments are available in this way.
+The PGN source files may also be listed in the argument file.
+They must be listed one per line, with a preceding colon
+character. So an alternative for the above would be:
+<pre>
+% Select games by Tal.
+:-TpTal
+% Where to output the matched games.
+:-otalgames.pgn
+% The game files to be read.
+:caro.pgn
+</pre>
+<p>and the command invoked as simply:
+<pre>
+pgn-extract -Aargs
+</pre>
+
+<p>The <a href="#-t">-t</a>, <a href="#-v">-v</a>, <a href="#-x">-x</a>,
+<a href="#-z">-y, -z</a>, and <a href="#-R">-R</a>
+flags have slightly special treatment in an argument file.
+Where the tags, variations, positions, endings and/or roster ordering
+are to be read from
+files of those names, say, then the format of these arguments in the
+argument file might be as you would expect:
+<pre>
+:-ttags
+:-vvariations
+:-xpositions
+:-zendings
+:-Rroster
+</pre>
+<p>However, within an argument file, the file names are optional and,
+where omitted, the data that would have been stored in a file for
+these flags is listed on lines immediately following.
+For instance, an alternative to:
+<pre>
+:-TpTal
+</pre>
+<p>we could say:
+<pre>
+:-t
+Player "Tal"
+</pre>
+<p>Notice that no colon should be present on the lines following the
+flag line.
+In the following example, we select games won by Tal as White
+reaching a particular position in the Caro Kann:
+<pre>
+:-t
+White "Tal"
+Result "1-0"
+:-otalwins.pgn
+:-x
+e4 c6 d4 d5 exd5 cxd5
+% Which game files to process.
+:caro.pgn
+</pre>
+<p>The arguments file may, itself, also contain -A arguments. This should
+make it possible to build up hierarchies of game selection criteria
+if desired. However, beware that there is no check for circularities
+in the dependencies.
+
+<h2 id="setup-tags">Matching only games with or without SetUp tags</h2>
+<p>Games with non-standard starting positions are indicated with a pair of tags:
+FEN and SetUp. Such games may be exclusively selected via --onlysetuptags or
+rejected via --nosetuptags.
+
+<h2 id="-n">Outputting games not matched (-n)</h2>
+<p>The -n flag will cause all valid games not output via other criteria to
+be saved in a given file. The purpose of this is to make it easier to
+reorganise files in different ways. For instance, if you wish to remove
+all of the games played by Tal from one file, you might do:
+<pre>
+pgn-extract -TpTal -otalgames.pgn -nothers.pgn file.pgn
+</pre>
+<p>After which, the file others.pgn will contain all of the valid games
+from the original file, with the exception of Tal's.
+
+<h2 id="nobadresults">Suppressing games with inconsistent results</h2>
+<p>By default, games in which the Result tag conflicts with the terminating result
+indication are retained, with an error message being output.
+Some obvious corrections are possible with <a href="#fixresulttags">--fixresulttags</a>
+but games in which the inconsistency cannot be resolved may be suppressed with
+--nobadresults.
+
+<h2 id="selectonly">Outputting selected matched games (--selectonly)</h2>
+<p>The --selectonly flag takes a comma-separated list of one or more numerical arguments representing
+ranges. For instance:
+<pre>
+1:10,15,89:94
+</pre>
+<p>requests that only the first 10, the 15th and the 89th-94th matched games are output.
+For instance, if only the first
+game played against Fischer is required from a file of Tal games, the following
+would be used:
+<pre>
+pgn-extract -TpFischer --selectonly 1 talgames.pgn
+</pre>
+<p>For the first three and the tenth, the arguments would be:
+<pre>
+pgn-extract -TpFischer --selectonly 1:3,10 talgames.pgn
+</pre>
+<p>The numbers in the list must be in strictly ascending order with no overlaps.
+Note that it is the number of <em>matches</em>
+that is used to select against and not the number of games in the input.
+<p>Note that, once the required games have been output, the program will terminate and
+not continue processing the rest of the input files.
+
+<h2 id="skipmatching">Suppressing the output of selected matched games (--skipmatching)</h2>
+<p>The --skipmatching flag takes a comma-separated list of one or more numerical arguments representing
+ranges, for instance:
+<pre>
+1:10,15,89:94
+</pre>
+<p>requests that the first 10, the 15th and the 89th-94th matched games are not output.
+For instance, if the first
+game played against Fischer is not required from a file of Tal games, the following
+would be used:
+<pre>
+pgn-extract -TpFischer --skipmatching 1 talgames.pgn
+</pre>
+<p>To suppress the first, second, third and fifth, the arguments would be:
+<pre>
+pgn-extract -TpFischer --skipmatching 1:3,5 talgames.pgn
+</pre>
+<p>The numbers in the list must be in strictly ascending order with no overlaps.
+Note that it is the number of <em>matches</em>
+that is used to skip against and not the number of games in the input.
+
+<h2 id="splitvariants">Output each variation as a separate game (--splitvariants)</h2>
+<p>The --splitvariants flag will output each variation of a game as a separate game.
+The headers of the containing game are reproduced for each variation, except for the Result tag, which is
+replaced with "*" to indicate that it is not necessarily a complete game.
+<p>The flag takes an optional positive integer to limit the depth of variants output as separate games.
+For instance: <code>--splitvariants 1</code> will only output separate variant games for top-level
+variants. Others are suppressed from the output. A value of 0 is used to output all variants and may be omitted.
+<p>The --splitvariants flag cannot be used with <a href="#suppress">the -V flag</a>.
+
+<h2 id="firstgame">Start matching from game number N (default 1) (--firstgame)</h2>
+<p>The --firstgame flag takes a single numerical argument N (N &gt;= 1) to
+request that matching only starts from game N, which is 1 by default.
+Games before game N are skipped for matching purposes.
+
+<h2 id="gamelimit>Only process up to and including game number N (--gamelimit)</h2>
+<p>The --gamelimit flag takes a single numerical argument N (N &gt;= 0) to
+request that only the first N games are analysed.
+
+<h2 id="stopafter">Stop after matching N games (--stopafter)</h2>
+<p>The --stopafter flag takes a single numerical argument N (N &gt; 0) to
+request that only the first N matched games are output.
+Note that it is the number of matches that determine the stopping point
+and not the number of games processed.
+<p>This is useful when processing large files but only a small sample of games are
+required.
+For instance, the following example would stop after it finds the first game
+by Petrosian in megafile.pgn:
+<pre>
+pgn-extract -TpPetrosian --stopafter 1 megafile.pgn
+</pre>
+
+<h2 id="notags">Don't output any tags (--notags)</h2>
+<p>The tags for a game will not be output.
+
+<h2 id="detag">Suppress a single tag (--detag)</h2>
+<p>All occurrences of the named tag will be omitted from the output of games.
+For instance:
+<pre>
+pgn-extract --detag Annotator --nocomments games.pgn
+</pre>
+<p>would remove all Annotator tags and comments from the given games.
+
+<h2 id="suppress">Suppress annotations in the output (-C -N -V)</h2>
+<p>If comments (-C or --nocomments),
+NAGs (-N or --nonags) and/or variations (-V or --novars) are not required in
+the output then these can be suppressed by using one or more of these flags.
+The -V flag cannot be used with <a href="#splitvariants">the --splitvariants flag</a>.
+
+<h2 id="nomovenumbers">Suppressing move numbers (--nomovenumbers)</h2>
+<p>Move numbers can be suppressed from the output with --nomovenumbers.
+Used in combination with
+<a href="#notags">--notags</a>,
+<a href="#noresults">--noresults</a>,
+<a href="#suppress">-C, -N, and -V</a>
+this can be used to output just the moves of a game:
+<pre>
+pgn-extract --nomovenumbers --noresults --notags -C -N -V file.pgn
+</pre>
+<p>If it is desired to have all the moves on a single line, use the <a href=
+"#-w">-w</a> flag as well.
+<p>See also the <a href="#plylimit">--plylimit</a> flag.
+
+<h2 id="noresults">Suppressing results (--noresults)</h2>
+<p>Results at the ends of games and variations
+can be suppressed from the output with --noresults.
+See <a href="#nomovenumbers">suppressing move numbers</a> for a possible use.
+
+<h2 id="plylimit">Limiting the number of plies (&gt;= 0) output
+		(--plylimit)</h2>
+<p>The number of moves (actually plies) output for a game can be limited
+by using --plylimit. This must be followed by the maximum
+number of plies to be output for a game.
+For instance,
+<pre>
+pgn-extract --plylimit 10 --nomovenumbers --notags file.pgn
+</pre>
+<p>will output games up to a maximum of 10 plies (including variation lines),
+without game tags and no line numbers.
+<p>See also <a href="#quiescent">--quiescent</a>.
+
+<p>Note: If the game has not ended before the ply limit is reached then *
+will be used as the terminating result to indicate an incomplete game (see
+<a href="#noresults">--noresults</a> for how to suppress this.)
+
+<h2><a id="dropbefore">Drop opening ply before a matching comment string (--dropbefore)</h2>
+<p>Use --dropbefore to output a game without the first few ply that occur before a matching
+comment string. For instance, given the following game fragment:
+<pre>
+1. e4 e5 { drop } 2. Nf3 Nc6 3. Bb5 *
+</pre>
+<p>after:
+<pre>
+pgn-extract --dropbefore drop
+</pre>
+<p>the output would be:
+<pre>
+[Event "?"]
+[Site "?"]
+[Date "????.??.??"]
+[Round "?"]
+[White "?"]
+[Black "?"]
+[Result "*"]
+[SetUp "1"]
+[FEN "rnbqkbnr/pppp1ppp/8/4p3/4P3/8/PPPP1PPP/RNBQKBNR w KQkq e6 0 1"]
+
+2. Nf3 Nc6 2. Bb5 *
+</pre>
+
+<h2 id="dropply">Drop the first N plies from a game (--dropply)</h2>
+<p>Use --dropply to output a game without the given number of ply.
+If a value of N greater than 0 appears after the argument then that
+number of plies are dropped from the beginning of the game.
+A FEN tag is output with the revised starting position.
+<pre>
+pgn-extract --dropply 2 file.pgn
+</pre>
+<p>will output the games in file.pgn without the first move of each side.
+<p>If a value less than 0 is used then all but that number of plies are dropped from the
+end of the game.
+<pre>
+pgn-extract --dropply -1 file.pgn
+</pre>
+<p>outputs the games in file.pgn with only their final move.
+
+<h2 id="quiescent">Position quiescence length (--quiescent)</h2>
+<p>Used only in conjunction with <a href="#plylimit">--plylimit</a>, this argument is used to
+defer termination of the output until the position has been quiescent for the given number of ply.
+Stability is defined as the absence of captures, checks and promotion.
+For instance:
+<pre>
+pgn-extract --plylimit 20 --quiescent 3 file.pgn
+</pre>
+<p>will output games up to 20 ply but only if there have been no captures, checks or
+promotion moves for the past 3 ply. If this condition is not met then moves will continue to be
+output until that condition is satisfied, or the end of the game is reached.
+
+<h2 id="move-bounds">Setting bounds on the number of moves or ply in a game (-b, -p, --minply, --maxply, --minmoves, --maxmoves)</h2>
+<p>The --minply, --maxply, --minmoves and --maxmoves are each followed by a number specifying the
+minimum (maximum) number of ply (moves) required in a game to match.
+The minimum and maximum options may be combined for imposing both lower and upper bounds.
+These long-form arguments perform a similar role to the alternative older single-character arguments described
+immediately below.
+<p>The -b flag allows you to select games which have a number of moves
+within the bounds you set.
+Alternatively, -p allows finer control over the number of ply.
+In all of the following examples of usage, if -b is replaced with -p then
+the numerical values apply to 'ply' rather than 'moves'.
+<p>You can set a lower bound on the number of moves
+by using -bl ('l' = lower bound), or an upper limit
+by using -bu ('u' = upper bound). Both are followed by
+the number of moves so
+<pre>
+pgn-extract -bu20 file.pgn
+</pre>
+<p>will find brevities of 20 moves or less, whilst
+<pre>
+pgn-extract -bl60 file.pgn
+</pre>
+<p>will find games of 60 moves or move. Bounds may be combined so
+<pre>
+pgn-extract -bl30 -bu40 file.pgn
+</pre>
+<p>will find games in the range [30..40] moves. If neither 'l' nor 'u'
+is used, but just a number following the -b, this means that the number
+of moves must exactly match that number. Alternatively, 'e' can be
+used to stand for 'equal to'. The following are equivalent and find
+all games of exactly 35 moves.
+<pre>
+pgn-extract -b35 file.pgn
+pgn-extract -be35 file.pgn
+</pre>
+<p>Note that the initial number of ply will be set from a FEN tag, if present, and
+therefore might not necessarily match the number of moves present in a
+particular game.
+
+<h2 id="-M">Matching only games that end in checkmate (-M or --checkmate)</h2>
+<p>The -M flag requests that only games that end in checkmate are matched:
+<pre>
+pgn-extract -M file.pgn
+</pre>
+
+<h2 id="fifty">Matching only games that include fifty or seventy-five moves with no capture or pawn move
+(--fifty, --seventyfive, --50, --75)</h2>
+<p>The --fifty flag requests that only games that contain at least fifty moves with no capture or
+pawn move are matched:
+<pre>
+pgn-extract --fifty file.pgn
+</pre>
+<p>The --seventyfive flag does the save for seventy-five moves.
+Shorthand alternatives are --50 and --75.
+<p>See <a href="#markmatches">--markmatches</a> for a way to mark the positions at which matches
+occur.
+
+<h2 id="repetition">Matching only games that include three-fold or five-fold repetition
+(--repetition, --repetition5)</h2>
+<p>The --repetition flag requests that only games that include three-fold repetition matched:
+<pre>
+pgn-extract --repetition file.pgn
+</pre>
+<p>The --repetition5 flag requests only games that include five-fold repetition.
+<p>In both cases, games will be matched regardless of whether the game was ended by that occurrence.
+See <a href="#markmatches">--markmatches</a> for a way to mark the position at which the
+repetition occurs.
+
+<h2 id="stalemate">Matching only games that end in stalemate (--stalemate)</h2>
+<p>The --stalemate flag requests that only games that end in stalemate are matched:
+<pre>
+pgn-extract --stalemate file.pgn
+</pre>
+
+<h2 id="underpromotion">Match only games that contain an underpromotion
+(--underpromotion)</h2>
+<p>The --underpromotion flag requests that only games that contain an
+underpromotion are matched:
+<pre>
+pgn-extract --underpromotion file.pgn
+</pre>
+
+<h2 id="-e">ECO Classification (-e)</h2>
+<p>A <a href="ftp://ftp.cs.kent.ac.uk/pub/djb/pgn-extract/eco.pgn">PGN
+file of ECO classifications</a> is distributed with this version. I
+believe that this was put together by Ewart Shaw, Franz Hemmer and
+others, to whom appropriate thanks is due.  The -e flag requests
+pgn-extract to add/replace ECO classifications in the games it outputs.
+This is done by firstly reading a file of ECO lines in PGN format
+(eco.pgn in the current directory, by default) and building a table of
+resulting positions. As the games are then read they are looked up in
+the table to find a classification. The deepest match is found.
+A match is allowed within six half moves of the length of the ECO line.
+The supplied file has ECO, Opening, and Variation tag strings for many
+lines. If present, pgn-extract will add/replace these as well as
+SubVariation tags if available.
+
+<p>An alternative file to the default eco.pgn may be supplied in two
+ways:
+<ul>
+    <li><p>Appending a file name to the -e flag
+<pre>
+-emy_eco_codes.pgn
+</pre>
+<p>Note that there must not be a space between the -e and
+the name of the file, otherwise the default ECO file will be assumed.
+    <li><p>By setting the environment variable ECO_FILE to the full path name
+of the file.
+Under Windows this can be done with
+<pre>
+set ECO_FILE=full-eco-file-path
+</pre>
+<p>at the Cmd window prompt, or more permanently via the
+System/Environment/Advanced area.
+Under UNIX csh this can be done with
+<pre>
+setenv ECO_FILE full-eco-file-path
+</pre>
+<p>in the .cshrc, for instance.
+</ul>
+
+<p>Having the ECO data read as plain text on program startup has the
+obvious disadvantage that there is a high initial time overhead. On the
+other hand, it has the advantage that users may add their own
+classifications to the file very easily.  It is fairly demanding of
+memory, so you advised not to combine this with duplicate detection
+(<a href="#-U">-U</a>,
+<a href="#duplicates">-D and -d</a>), which can also consume a lot
+of memory with big databases.
+
+<p>Because an ECO tag match with either the <a href="#-t">-t flag</a> or
+the <a href="#-T">-T flag</a> is delayed until after ECO 
+classification, this makes it relatively easy to select games with
+particular ECO codes even if they weren't present in the source form.
+
+<p>Usage of -e with the Seven Tag Roster flag (<a href="#-7">-7</a>)
+results in the ECO
+tags (ECO, Opening, Variation, SubVariation) being included in the
+output games.
+
+<h2 id="separate-output">Separate output files (-#, -E)</h2>
+<p>The -# and -E flags permit the output to be split into multiple files.
+However, be warned that where the input involves a lot of games,
+these flags might result in the creation of a large number of output files.
+
+<p>The -# flag takes an unsigned integer argument specifying the maximum number
+of games to output to a single file. Successive output files are numbered 1.pgn,
+2.pgn, etc. unless a second number is given (see below).
+Any existing contents of these files are always overwritten on each
+run of pgn-extract.
+<pre>
+pgn-extract -#250 file.pgn
+</pre>
+<p>will split file.pgn into separate files of, at most, 250 games each.
+<pre>
+pgn-extract -#1 file.pgn
+</pre>
+<p>will split file.pgn into separate files containing only a single game each.
+<p>If the number of games per file is followed by a comma and a second unsigned integer,
+then the second number is used as the name of the first output file.
+For instance, 
+<pre>
+pgn-extract -#1,100 file.pgn
+</pre>
+will write games to files called 100.pgn, 101.pgn, etc.
+
+<p>The -E flag normally takes a numeric argument of value 1, 2, or 3. This is
+used to indicate the level of subdivision required based upon the ECO tag
+found in a game.
+<pre>
+pgn-extract -E3 file.pgn
+</pre>
+<p>will fully subdivide file.pgn into separate files based on the full ECO
+code of each game, with names such as B03.pgn, A01.pgn, D45.pgn, etc.
+If a game does not contain an ECO tag, or the tag appears to be malformed,
+it will be written to a file called, noeco.pgn. All of these files are
+written to in append mode, so that existing contents are not lost. However,
+beware of using an input file whose name is the same as one that will be
+written to by this operation. This could lead to infinite operation.
+
+<p>Level 1 classification uses just the initial letter of the ECO
+classification to append to files A.pgn, B.pgn, etc. Level 2 uses the initial
+letter and first digit, producing A0.pgn, B3.pgn, etc.
+
+<p>In fact, values greater than 3 may be used to produce separation of even
+finer granularity if more than two digits have been used in the classification
+of a game.
+
+<h2 id="-S">Soundex matching (-S)</h2>
+<p>There is a simple soundex algorithm available that attempts soundex
+matches on White, Black, Site, Event, and Annotator tags if the -S flag
+is used in combination with either the <a href="#-t">-t flag</a> or
+the <a href="#-T">-T flag</a>.  The -S flag should
+precede all -t and -T arguments.  It should be noted that the soundex
+matching does produce false matches.
+
+<h2 id="-w">Output line length (-w or --linelength)</h2>
+<p>The -w flag allows an approximate line length to be set for output.
+Normally games are output with lines up to a maximum of 75 characters.
+Use the -w flag if you want longer output lines.
+For instance, you might want all the moves of a game to appear on a single
+line. You would get this effect by specifying -w1000 (say):
+<pre>
+pgn-extract -w1000 file.pgn
+</pre>
+<p>If some games are more than 1000 characters long then just increase the value.
+
+<h2 id="-W">Output format and language (-W)</h2>
+<p>By default, pgn-extract rewrites the game score into English Standard Algebraic
+Notation (SAN) because it is reasonably flexible about the input form
+that it will accept.  To prevent it from rewriting the original form of
+the moves it reads, use the -W flag.
+Note that Chess960 games must have the Variant tag set to "chess 960" to be
+recognised as such. This affects the encoding of castling moves when output
+in long-algebraic format.
+<ul>
+  <li>By itself, -W outputs the moves using the input text.
+  <li>Using -Whalg writes the moves in hyphenated long algebraic (e.g., e2-e4).
+  <li>Using -Wlalg writes the moves in long algebraic form (e.g., e2e4).
+  <li>Using -Welalg writes the moves in enhanced long algebraic form (e.g.,
+  Ne2e4, e5d6ep). The purpose of enhanced long algebraic form is to reduce the
+  amount of chess-specific knowledge that a post-procesing program might
+  need in order to interpret a chess game.
+  For instance, in order to provide a visualisation.
+  <li>Using -Wxlalg writes the moves in enhanced hyphenated long algebraic form with capture information (e.g., Ng1-f3, Nf6xd5, e5xd6ep).
+  The purpose of enhanced long algebraic form with hyphens and x's is to further reduce the amount
+  of chess-specific knowledge that a post-processing program might need in order to interpret a chess game.
+  <li>-Wxolalg is a variation on -Wxlalg that outputs O-O and O-O-O for the castling moves.
+  <li>Using -Wuci causes the moves of the game to be output in
+  a format that should close to being suitable for input to a
+  <a href="http://wbec-ridderkerk.nl/html/UCIProtocol.html">UCI-compatible</a> engine.
+  The output format is the same as with -Wlalg but all comments, NAGs,
+  variations, move numbers and checks removed.
+  In addition the whole game is output on a single line.
+  <br>This format is compatible with my
+  <a href="https://www.cs.kent.ac.uk/~djb/uci-analyser/">UCI-analyser</a>
+  and could be used as part of a process to
+  <a href="https://www.cs.kent.ac.uk/~djb/uci-analyser/#annotatePGN">annotate games with engine analysis</a>.
+</ul>
+
+<p>Output using non-English piece letters is possible using a variation
+of the -Wsan flag. This flag may have a six-letter suffix indicating
+the letters to be used in representing pawn, knight, bishop, rook,
+queen and king in game scores and diagrams. So:
+<pre>
+pgn-extract -WsanPNBRQK ...
+</pre>
+<p>would output in the (default) English notation, and
+<pre>
+pgn-extract -WsanBSLTDK ...
+</pre>
+<p>would output in German. Note that the letter for a pawn is required because
+board positions are sometimes output when an error is detected in
+a game score.
+
+<p>-Wepd outputs in EPD (Extended Position Description).
+A game is output as a sequence of EPD descriptions of
+the position at the start of the game, and following each move.
+Each EPD line contains the FEN board description, the active colour,
+castling availability and en passant target square. A c0 comment contains
+a synopsis of the player, event, site and date tags from the game's header.
+A c1 comment contains the game's result.
+
+<p>-Wfen outputs the game as a sequence of FEN positions along with the game tags but no result.
+The tags may be suppressed with the --notags option.
+Note that the output from this option is not valid PGN and it has been provided solely
+as a convenient way to obtain the FEN sequence for a game.
+
+<p>-Wuci outputs in long-algebraic notation (-Wlalg) but also strips the
+game of everything apart from its moves, tags and result.
+It provides the equivalent of using the following multiple arguments:
+<pre>
+-Wlalg -C -N -V -w5000 --nomovenumbers --nochecks
+</pre>
+
+<p>Use the --noresults and --notags options if tags and results are also
+to be removed.
+
+<p>-Wcm is an obsolete legacy flag and
+outputs the moves in what I believe to be (or used to be) ChessMaster format.
+
+<h2 id="commentlines">Output each comment on a separate line</h2>
+<p>The --commentlines flag will break game output at the start and
+end of a comment so that comments appear on separate lines from the game
+text.
+
+<h2 id="linenumbers">Include a comment with a game's line numbers from the input file</h2>
+<p>The --linenumbers argument is followed by a marker string and the result is that a comment is added
+to each matched game between the tags and the moves. The comment contains the marker string and the start
+and end line numbers of where the game originated from in its input file.
+For instance:
+<pre>
+pgn-extract --linenumbers marker games.pgn
+</pre>
+<p>would include comments such as <code>{ marker:1:20 }</code> and <code>{ marker:22:35 }</code>.
+
+<h2 id="-F">Forsyth-Edwards Notation (FEN) descriptions (-F)</h2>
+<p>The -F flag provides a way to generate
+a suitable FEN description of an arbitrary position.
+The -F flag, with no additional text, causes pgn-extract to output a FEN description of the final
+position reached in a game, within the text of a comment.
+For instance, suppose you were interested in finding games that
+reach the position after the following moves.
+<pre>
+d4 Nf6 c4 e6 Nf3 b6 Nc3 Bb7 e3 Bb4 Bd3 O-O O-O Bxc3 bxc3 c5 *
+</pre>
+<p>Storing these moves in the file fen.pgn and running
+<pre>
+pgn-extract -F fen.pgn
+</pre>
+<p>would generate the score:
+<pre>
+[Event "?"]
+[Site "?"]
+[Date "????.??.??"]
+[Round "?"]
+[White "?"]
+[Black "?"]
+[Result "*"]
+
+1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. Nc3 Bb7 5. e3 Bb4 6. Bd3 O-O 7. O-O Bxc3 8.
+bxc3 c5 
+{ "rn1q1rk1/pb1p1ppp/1p2pn2/2p5/2PP4/2PBPN2/P4PPP/R1BQ1RK1/ w - c6 0 9" } *
+</pre>
+<p>The FEN string thus generated might then be used with the <a href="#-t">-t flag</a>
+to match games reaching that position. The FEN string above
+would be cut and pasted to <a href="#-A">an argument file</a> and used with
+the <a href="#-t">-t flag</a> to supply matches:
+<pre>
+:-t
+FEN "rn1q1rk1/pb1p1ppp/1p2pn2/2p5/2PP4/2PBPN2/P4PPP/R1BQ1RK1/ w - c6 0 9"
+</pre>
+<p>A variation of -F, when immediately followed by a text string, allows a FEN 
+position of an arbitrary point in a game to
+be output as a comment.
+For instance, the following:
+<pre>
+pgn-extract -FputFENhere file.pgn
+</pre>
+<p>would replace all comments of the form <code>{ putFENhere }</code> encountered
+in games in file.pgn with a comment containing the FEN position at that point. 
+For instance, if file.pgn contained:
+<pre>
+d4 Nf6 c4 e6 Nf3 b6 { putFENhere } Nc3 Bb7 e3 Bb4 Bd3 O-O O-O { putFENhere }
+Bxc3 bxc3 c5 *
+</pre>
+<p>the output would be:
+<pre>
+[Event "?"]
+[Site "?"]
+[Date "????.??.??"]
+[Round "?"]
+[White "?"]
+[Black "?"]
+[Result "*"]
+
+1. d4 Nf6 2. c4 e6 3. Nf3 b6 {
+rnbqkb1r/p1pp1ppp/1p2pn2/8/2PP4/5N2/PP2PPPP/RNBQKB1R w KQkq - 0 4 } 4. Nc3
+Bb7 5. e3 Bb4 6. Bd3 O-O 7. O-O {
+rn1q1rk1/pbpp1ppp/1p2pn2/8/1bPP4/2NBPN2/PP3PPP/R1BQ1RK1 b - - 4 7 } 7...
+Bxc3 8. bxc3 c5 *
+</pre>
+<p>The text immediately following -F is arbitrary but an exact, complete match
+is required to output a FEN string.
+<p>See <a href="#fencomments">--fencomments</a> for the option to add
+a FEN comment after every move, including the final one.
+
+<h2 id="-z">Material matches (-y, -z, --materialy, --materialz and --addmatchtag)</h2>
+<p>The -y and -z flags take a filename of material balances for which you
+wish to search in games.
+The --materialy and --materialz arguments offer command-line alternatives to
+using a file.
+<p>The basic structure of the file is one or more lines describing a material
+balance of the form
+<pre>
+pieces1 pieces2
+</pre>
+<p>Pieces1 and pieces2 are lists of English piece letters for the material
+for the two sides that you wish to look for in a game.
+For instance:
+<pre>
+rp nb
+</pre>
+<p>looks for a game in which a lone Rook and Pawn are
+competing against a lone Knight and Bishop for the other.
+<p>The case of the
+letters is immaterial and the order of the pieces does not matter. 
+There is no need to include Kings in the description except for the
+special case where pieces1 would otherwise be empty.
+For instance, to find matches where Black has a single pawn and White only
+has a King the description would be
+<pre>
+k p
+</pre>
+<p>
+Apart from Kings, if a piece letter is not listed for a side then that piece
+is not present within that side's material.
+With the -z and --materialz flags, a match will be tested for from both White and Black's point of view,
+so with -z the example above matches the same games as:
+<pre>
+bn pr
+</pre>
+<p>However, if this is used with the -y or --materialy flag then only games in which Black
+has the Rook will be searched for.
+<p>Further notation may be added after any piece letter, typically to
+indicate something about the number of occurrences of that piece on one
+side.
+The following are valid for each piece:
+<ul>
+    <li>* (zero or more of that piece).
+    <li>+ (one or more of that piece).
+    <li>d (exactly d occurrences of that piece, where d is a digit).
+    <li>d+ (d or more occurrences of that piece).
+    <li>d- (d or fewer occurrences of that piece).
+</ul>
+<p>So:
+<pre>
+QR2B2N2P8 QR2B2N2P8
+</pre>
+<p>is the starting material position.
+<p>Further notation is available to specify material
+relative to the opponent's.
+These are placed after the piece letter to which they refer.
+<ul>
+    <li>= (the number of these pieces must be the same as the opponent's).
+    <li># (the number of these pieces must be different from the opponent's).
+    <li>&gt; (the number of these pieces more than the opponent has).
+    <li>&lt; (the number of these pieces less than the opponent has).
+</ul>
+<p>So,
+<pre>
+R+P+ R=P#
+</pre>
+<p>looks for Rook and Pawn games with a non-zero equal number of Rooks but
+unbalanced pawns.
+
+<p>In addition &gt; and &lt; may be preceded by a digit:
+<ul>
+    <li>d&gt;
+    (the number of these pieces must be at least d more than the opponent's).
+    <li>d&lt;
+    (the number of these pieces must be at least d less than the opponent's).
+</ul>
+<p>Two more notations, &gt;=, &lt;= may be preceded by an optional digit
+(the default is 1).
+The meaning of this may not be intuitively obvious and, to an extent, they
+represent a notational compromise.
+<ul>
+    <li>d&gt;=
+    (the number of these pieces must be exactly d more than the opponent's).
+    <li>d&lt;=
+    (the number of these pieces must be exactly d less than the opponent's).
+</ul>
+<p>In this example, both sides have a pair or Rooks but one has exactly one
+pawn more than the other:
+<pre>
+r2p* r=p1&gt;=
+</pre>
+<p>Here is an example where one side has sacrificed a Rook and Pawn for
+Knight and Bishop and we don't care whether Queens are on or off the
+board, so long as they are balanced:
+<pre>
+q*r+n*b*p+ q=r&lt;n&gt;b&gt;p1&lt;
+</pre>
+<p>This example represents some of the imprecision that can occur with
+matches.  The meaning of 'r&lt;' is such that this could match positions
+in which one side as 2 Rooks and the other none. This can be corrected
+with:
+<pre>
+q*r+n*b*p+ q=r1&lt;=n&gt;b&gt;p1&lt;
+</pre>
+<p>enforcing strictly one Rook less. We ought also to correct the same
+problem with the minor pieces:
+<pre>
+q*r+n*b*p+ q=r1&lt;=n1&gt;=b1&gt;=p1&lt;
+</pre>
+<p>In practice, we probably want to allow general matching of minor pieces
+so the letter 'L' may be used to stand for a minor piece (Bishop or
+Knight). This example represents a similar sacrifice of Rook and Pawn for
+two minor pieces.
+<pre>
+q*r+l*p+ q=r1&lt;=l2&gt;=p1&lt;
+</pre>
+<p>I would advise against mixing the minor piece letter with Knight and
+Bishop letters in the piece set for a single side, however, as I am not
+convinced that it will produce exact results.
+
+<p>Given the following pattern:
+<pre>
+q*r*b2n0p* q=r=b0n2p=
+</pre>
+<p>the -y flag would find all games where White had a Bishop pair and Black had two Knights,
+whereas the -z flag would find all BB vs NN games for both sides.
+
+With both --materialz and --materialy the full pattern must be supplied as a single command-line
+string; for instance:
+<pre>
+pgn-extract --materialz "q*r*b2n0p* q=r=b0n2p=" games.pgn
+</pre>
+
+<p>The --addmatchtag argument can be used with -z or --materialz to add a MaterialMatch tag
+pair to a game. The associated string will be "White" if pieces1 matches the
+White pieces or "Black" if pieces1 matches the black pieces.
+If this argument is used with -y or --materialy then the associated string will always be
+"White" so there is no point combining --addmatchtag with -y.
+
+<p>A comment line may be placed in a material balance file by using a '%'
+as the first character of the line.
+
+<p>The <a href="#markmatches">--markmatches</a> flag may
+be used to add a comment at the point that the match is found.
+<ul>
+<li><p>Position Stability with -z<br />
+<p>The piece sets may be preceded by an optional number indicating the
+required stability of the position. Normally, if you are looking for a
+position with a particular set of material characteristics then you
+probably want that position to last for a reasonable number of moves in
+order to study its characteristics. The number before the piece sets is
+how many half-moves you wish that material balance to last. By default,
+this has a value of 2 so that fleeting positions in the middle of pairs
+of exchanges do not produce unwanted matches.
+This example looks for double-Rook and pawn games that last at least
+10 half-moves:
+<pre>
+10 R2P+ R=P*
+</pre>
+</ul>
+
+<h2 id="-7">The Seven Tag Roster (-7 or --seven)</h2>
+<p>This flag discards tag pairs that are not part of the Seven Tag
+Roster:
+<pre>
+Event, Site, Date, Round, White, Black and Result.
+</pre>
+<p>However, if the original game included a FEN tag, this is
+included in the output, as the moves will make no sense
+otherwise. In addition, if <a href="#-e">the -e flag</a> has been used for ECO
+classification, any ECO, Opening, Variation and SubVariation tags
+are also output.
+
+<h2 id="-R">User-defined tag roster ordering (-R)</h2>
+<p>The -R flag makes it possible to define the order in which
+tags for a game are listed in the output.
+The flag should be immediately followed by the name of a file
+that contains a list of tag names, one per line, for instance:
+<pre>
+pgn-extract -Rroster file.pgn
+</pre>
+<p>where roster might contain:
+<pre>
+% Output the tags of the seven tag roster alphabetically.
+Black
+Date
+Event
+Result
+Round
+Site
+White
+</pre>
+<p>The '%' character may be used to include comments in the file.
+Tags not listed in such a file will appear after the required
+tags have been output.
+
+<h2 id="evaluation">Include a position evaluation after each move (--evaluation)</h2>
+<p>The --evaluation argument causes a comment to be appended to every move,
+which contains an evaluation of the position immediately following that
+move.
+The default evaluation is a simplified version of 
+<a href="http://en.wikipedia.org/wiki/Claude_Shannon">Shannon's board
+evaluation</a>. In this case, the evaluation is the difference between the
+value of White's position and Black's, where the value of a position is
+a weighted sum of the pieces plus a multiplier (0.1) applied to
+the number of available moves for that player.
+
+<p>I see this primarily as being a hook for people who wish to embed their
+own evaluations in the output.
+See the <code>evaluate</code> function in <code>apply.c</code> if you wish to
+write your own.
+
+<p>However, an alternative approach to annotating games with engine analysis would
+be to consider using something like my
+<a href="https://www.cs.kent.ac.uk/~djb/uci-analyser/">UCI-analyser</a> that can
+pass suitably formatted PGN files to a
+<a href="http://wbec-ridderkerk.nl/html/UCIProtocol.html">UCI-compatible</a> engine.
+See, for instance, the section on obtaining
+<a href="https://www.cs.kent.ac.uk/~djb/uci-analyser/#annotatePGN">annotated output in PGN format</a>.
+
+<h2 id="fencomments">Include a comment with a FEN string for
+the position after each move (--fencomments)</h2>
+<p>The --fencomments argument causes a comment to be appended to every move,
+which contains a FEN string for the position immediately following that
+move. See <a href="#-F">-F</a> for adding a comment after just the
+final move.
+
+<h2 id="hashcomments">Include a polyglot hashcode comment after each move (--hashcomments)</h2>
+<p>After every move a 16-character hexadecimal polyglot hashcode is output in a comment.
+The idea is to make it easy to identify the hashcode associated with a position,
+for instance for use with hashcode searches (see <a href="#-H">-H</a>).
+
+<h2 id="nofauxep">Don't output ep squares in FEN when the capture is not possible (--nofauxep)</h2>
+<p>FEN descriptions include the square for a possible en passant capture regardless of whether there
+is actually an opposing pawn in position to make the capture.
+For instance, if there is no opposing pawn, or the capture would leave the capturing
+side in check.
+The --nofauxep flag suppresses output of the square when a capture is not possible.
+This makes it easier to compare identical FEN positions resulting from transpositions.
+
+<h2 id="markmatches">Add a game comment on positional, material, repetition and fifty-move rule
+matches (--markmatches)</h2>
+<p>Add a game comment with the text immediately following --markmatches
+after the move which causes a positional, material, repetition or fifty-move rule match.
+For instance:
+<pre>
+pgn-extract -xvars --markmatches MATCH file.pgn
+</pre>
+<p>would add the comment <em>{ MATCH }</em> after every move that
+caused a match from the positional matches specified in the <em>vars</em> file.
+<p>If the text FEN is used then this is interpreted to mean that the FEN encoding
+of the match position should be output in the comment, rather than the literal
+text FEN.
+
+<p>See <a href="#-x">-x</a> for positional matches with moves,
+<a href="#fen-t">-t</a> for positional matches with FEN patterns,
+and <a href="#-z">-z</a> for material matches.
+See also <a href="#fifty">--fifty</a> and <a href="#repetition">--repetition</a>.
+
+<h2 id="addhashcode">Add a Tag containing a hashcode for the game (--addhashcode)</h2>
+<p>Add the tag HashCode to the tags. This contains a hashcode value
+generated from the moves of the game. Identical move sequences will
+produce the same hash code.
+
+<h2 id="addfencastling">Add potentially missing castling rights to FEN tags
+        (--addfencastling)</h2>
+<p>If no castling rights are indicated in the FEN tag of a game (-) then liberally
+interpret the initial positions of Kings and Rooks to infer the rights.
+NB: This is not implemented for Chess 960 positions.
+
+<h2 id="fixresulttags">Correct Result tags that conflict with the game outcome or terminating result (--fixresulttags)</h2>
+<p>Where the existing Result tag clearly conflicts with a game's outcome - i.e., checkmate or stalemate - replace
+the value in the Result tag to match the game outcome and don't report the inconsistency.
+<p>Inconsistencies between the result tag and terminating result are resolved in favour of
+    the terminating result when either is "*".
+
+<h2 id="fixtagstrings">Attempt to correct tag strings that are not properly terminated (--fixtagstrings).</h2>
+<p>Tag strings sometimes contain extra, unescaped quote characters within them.
+This option attempts to fix those errors.
+
+<h2 id="plycount">Add a PlyCount tag (--plycount)</h2>
+<p>Add the tag PlyCount to the tags. This contains a count of
+the number of ply present in the game being output.
+Unless <a href="#suppress">variations have been suppressed</a> this will include
+all moves in variations as well as the main line.
+
+<h2 id="totalplycount">Add a Tag containing the total ply count (--totalplycount)</h2>
+<p>Add the tag TotalPlyCount to the tags. This contains a count of
+the <em>total</em> number of ply present in the game being output.
+Unless <a href="#suppress">variations have been suppressed</a> this will include
+all moves in variations as well as the main line.
+
+<h2 id="nestedcomments">Allow nested comments (--nestedcomments)</h2>
+<p>Nested comments are not usually allowed, but some game sources include them.
+Use --nestedcomments to avoid mismatched closing comment symbols.
+
+<h2>Single-line comments</h2>
+<p>Single line comments introduced via a semicolon (;) character are recognised.
+They are converted in the output to multi-line comments with curly
+braces. Curly braces within them are converted to square brackets.
+
+<h2 id="lichess">Move lichess comments (--lichesscommentfix)</h2>
+<p>Move comments that occur immediately after the opening parenthesis of a variation (i.e., before the
+variation's first move) to after the first move.
+This was introduced to get around a feature of lichess studies.
+
+<h2 id="mailing">Contacting the author</h2>
+<p>I don't run a mailing list but if you find the program useful
+and would like or to offer suggestions that you think
+others might be interested in, then drop me a line at
+<a href="mailto:d.j.barnes@kent.ac.uk">d.j.barnes@kent.ac.uk</a>
+
+<h2 id="limitations">Limitations</h2>
+<p>The moves, variations, and commentary of each game are held internally
+and reformatted when a game is extracted, rather than reproducing the
+original text of the game source.
+
+<p>Lower-case 'b' as the first character of a move is taken to be a move
+of the b-pawn if one to match the move can be found. Otherwise, Bishop
+moves are tried as an alternative.  There is no back-up on failure if
+picking a valid pawn move was the wrong choice.
+
+<p>Lower-case 'b' as the first character of a Bishop move is not
+acceptable in the variations files.
+
+<p>Duplicate detection is not guaranteed to be exact.
+The -Z flag has slightly more potential to avoid false duplicates
+as it compares separate values for the end position and move sequence,
+whereas these are XORed to save space when -Z is not used.
+However, this will only make a difference and avoid false
+matches if
+two different games at the same hashtable index
+also produce identical XORed values.
+
+<p>The results of the -x, -v, and -t/-T search criteria are AND-ed
+together.  There might be occasions when you wanted to search for games
+that matched either positional variations or textual variations at the
+same time, for instance.  This requires multiple runs of pgn-extract.
+
+<p>The -Wsan variation that allows selection of the output language
+is tied to single-character piece descriptions. This does
+not support Russian usage, for instance, in which the King
+is described as a character pair.
+
+<h2 id="files">The files</h2>
+<p>The sources include a Makefile for the GNU make program, gmake.

+
+<h2 id="acknowledgements">Acknowledgements</h2>
+<p>I would like to thank all those who used the program and made
+suggestions for things to add.  In particular, thanks to Michael Kerry
+whose help led to better determination of game boundaries in earlier
+versions, and V. Armando Sole whose own filter
+program was the inspiration for adding textual variation permutations.
+John Brogan suggested adding the ! notation to the variation file and
+provided the spur for duplicate detection.
+He also supplied the original code for soundex matching (-S).
+<p>Jaroslav Poriz, Ron Leamon, Ed Leonard, Charles
+Frohman, and Robert Wilhelm helped with testing at various times.
+Bernhard Maerz was instrumental in encouraging the inclusion of ECO
+classification and material balance matches.
+He and Peter Otterstaetter
+suggested the relational operators in tag files, with Peter also
+providing the spur to make duplicate detection work with bigger game files
+(-Z) and doing some very useful testing for me.
+<p>Kayvan Sylvan requested
+long algebraic output and identified an error in ECO classification.
+Cameron Hayne suggested matching on the number of moves in a game.
+Owen D. Lyne suggested extension of the -E flag,
+and both tested and provided diagnostic data to help refine the
+ECO classification aspects of the program.
+Karl-Martin Skontorp provided the incentive and testing help that
+enabled me to add the -Wepd option.
+<p>FEN pattern matching is based on pattern matching code by Rob Pike.

+and ideas from Kernighan and Plauger's "Software Tools".
+<p>Finally, thanks, of course, to Steven Edwards
+for his work on developing the PGN standard.

+<h2>Introduction</h2>
+<p>This is the home page for
+the <em>pgn-extract</em> program,
+which is a <em>command-line</em> program for searching, manipulating and formatting
+chess games recorded in the Portable Game Notation (PGN) or something close. It
+is capable of handling files containing millions of games. It also recognises Chess960
+encodings.
+<p>A <a href="https://www.cs.kent.ac.uk/people/staff/djb/pgn-extract/help.html">full
+description of pgn-extract's functionality</a> is available and included
+with the sources.
+
+<p>Here you can find the C source code and Windows binaries for the current
+version.
+pgn-extract compiles and runs under Windows, Linux and Mac OS X.
+This program is made available under the terms of the
+<a href="https://www.cs.kent.ac.uk/~djb/pgn-extract/COPYING">GNU
+General Public License (Version 3).</a>
+
+<h2>Getting-started video for Windows users</h2>
+<p>For Windows users who are really only interested in getting
+the binary working, there is <a href="https://www.cs.kent.ac.uk/~djb/pgn-extract/intro.mp4">a short introductory video</a>.
+
+<h2>Overview</h2>
+<p>The program is designed to make it easy to extract and format selected games from a
+PGN format data file based on a wide variety of criteria.
+The criteria include:
+<ul>
+<li><p>textual move sequences;</p></li>
+<li><p>the position reached after a sequence of moves;</p></li>
+<li><p>information in the tag fields;</p></li>
+<li><p>fuzzy board position;</p></li>
+<li><p>and material balance in the ending.</p></li>
+</ul>
+<p>Over the on-going 20+ year course of its development, it has also added
+lots of features for controlling what is output (e.g., different
+algebraic formats, EPD, no move numbers, restricting game length, etc.)
+
+<p>The program includes a semantic analyser which will
+report errors in game scores and it is also able to detect duplicate
+games found in its input files.
+
+<p>The range of input move formats accepted is fairly wide.
+The output is normally in English Standard
+Algebraic Notation (SAN) but this can be varied to long-algebraic or UCI,
+for instance.
+
+<p>Extracted games may be written out either including or excluding
+comments, NAGs, variations, move numbers, tags and/or results.
+Games may be given ECO classifications
+derived from the accompanying file eco.pgn, or a customised version
+provided by the user.
+
+<p>The program is designed to be relatively memory-friendly, so it
+does not retain a game's moves in memory once it has been processed.
+This also makes it suitable for bulk processing very large collections of games
+- it can efficiently process files containing several millions of games.
+
+<p>Use the <em>--help</em> argument to the program to
+get the full lists of arguments.
+
+<h2>New in recent versions</h2>
+<p>These are the main changes in the most recent versions:
+<ul>
+    <li><p>Extended matching of TimeControl to include the formats
+    of sudden death and sandclock.
+    <li><p>Added --detag to delete tags that are not required.
+    <li><p>Added --addfencastling to add potentially missing castling rights to FEN tags.
+    <li><p>Made duplicate suppression work with input from stdin.
+    <li><p>Added --deletesamesetup to identify unique starting positions.
+    <li><p>Added -Wfen to output a game as a sequence of FEN positions.
+</ul>
+

+<h2>Blog post about data mining with pgn-extract</h2>
+<p>In October 2018 I wrote <a href="http://blogs.kent.ac.uk/djb/2018/10/14/data-mining-with-pgn-extract/">blog post</a>
+about using pgn-extract to mine a PGN database. 
+As an example it looks at the effect of having a bishop pair versus a knight pair.
+
+<h2>Answers on Chess StackExchange using pgn-extract</h2>
+<p>I am active on <a href="https://chess.stackexchange.com/">Chess StackExchange</a> as
+<a href="https://chess.stackexchange.com/users/12951/kentdjb">kentdjb</a>
+and aim to respond to pgn-extract related questions, although email to me is my preferred way to raise
+potential issues with the program.
+<p>From time to time, I have provided answers to questions that involve
+the use of pgn-extract for analysis tasks:
+<ul>
+  <li><p><a href="https://chess.stackexchange.com/questions/23938/is-there-a-record-for-threefold-repetition-for-when-the-claimed-positions-are-th/24276#24276">Three-fold repetition</a>.
+  <li><p><a href="https://chess.stackexchange.com/questions/24166/what-professional-game-has-the-quickest-sequence-starting-from-move-one-to-qua/24274#24274">Quadrupled pawns</a>.
+  <li><p><a href="https://chess.stackexchange.com/questions/24245/how-often-does-castling-occur-in-grandmaster-games/24247#24247">Frequency of occurrence of castlng</a>.
+</ul>
+
+<h2>Feedback</h2>
+<p>Feedback and suggestions for further features are always welcome, although I can't always
+promise to undertake significant development work.

+.TH PGN-EXTRACT 1 "May 19, 2013"
+.SH NAME
+pgn-extract - a Portable Game Notation (PGN) extractor
+.SH SYNOPSIS
+.B pgn-extract
+[flags] file.pgn [file.pgn ...]
+.SH DESCRIPTION
+.B pgn-extract
+is a free, open-source program pgn-extract, which is designed to
+support the processing, searching and extraction of chess games from
+files written in PGN format. There are several ways to specify the
+criteria on which to extract: textual move sequences, the position
+reached after a sequence of moves, information in the tag fields, and
+material balance in the ending. Full ANSI C source and a 32-bit
+Windows binary for the program are available under the terms of the
+GNU General Public License. The program includes a semantic analyser
+which will report errors in game scores and it is also able to detect
+duplicate games found in one or more of its input files.
+
+The range of input move formats accepted is fairly wide and includes
+recognition of lower-case piece letters for English and upper-case
+piece letters for Dutch and German. The default output is in English
+Standard Algebraic Notation (SAN), although there is some support for
+output in different notations.
+
+Extracted games may be written out either including or excluding
+comments, NAGs, and variations. Games may be given ECO classifications
+derived from the accompanying file eco.pgn, or a customised version
+provided by the user.
+
+Plus, lots of other useful features that have gradually found their
+way into what was once a relatively simple program!
+.SH OPTIONS
+Run
+.B pgn-extract -h
+to get all the options.
+
+A complete description of each option can be found in
+.B /usr/share/doc/pgn-extract/help.html
+.SH AUTHOR
+pgn-extract was written by David J. Barnes <d.j.barnes@kent.ac.uk>.
+
+This manual page was written by Peter van Rossum <petervr@debian.org>
+and Vincent Legout <vlegout@debian.org>, for the Debian GNU/Linux
+system.

+    Date matches extended to match on month and day as well as year and a few more
+    command-line options: --fixtagstrings attempts to fix common bad string formats
+    in tag strings; and --wtm/--btm add the requirement for white-to-move/black-to-move
+    in matches.
