+If compiling with Visual C, the CHUNK_LIMIT poses problems.
+Problem is, that VC2008 seems to have a too small default stack, which is not
+big enough. With default command line parameters it will crash.
+The workaround is to give the command line parameter /F. With this you can
+increase the stack to a certain size. Setting it to 2 MB is good enough
+
+ZLIB might also pose problems. If you cannot correctly compile it under

+GCC bug
+----------
+Beware, GCC has a bug affecting propagation in CryptoMiniSat:
+
+http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47365
+
+This seems to affect all gcc versions 4.5.x and is latent in
+trunk of upcoming 4.6.0
+
+-----------
+Libraries needed
+-----------
+You will need the following libraries to compile the sources:
+* libz
+
+-----------------
+Building the source
+-----------------
+There are two ways to build the source. With cmake or with autotools.
+I personally use cmake.
+
+------------------
+Building using autotools
+------------------
+$ mkdir build
+$ cd build
+$ ../configure
+$ make
+
+Use like: ./cryptominisat satfile.cnf
+
+If you got your source from the GIT/SVN, then you should do the following
+before doing the above::
+* Install automake, autoconf, libtool
+* Issue 'make -f Makefile.cvs' in the root dir
+
+---------
+Please read help
+---------
+For help, build the program, and issue:
+'./cryptominisat -help'
+
+--------------
+Verbose debug
+-------------
+You can also turn on verbose debugging.
+Simply remove the comment before
+
+"//#define VERBOSE_DEBUG"
+in Solver/constants.h and re-compile
+
+When executing:
+
+'./cryptominisat satfile.cnf'
+You will see a LOT of debug info. You should therefore maybe do:
+
+'./cryptominisat satfile.cnf > debuginfo.txt'
+then you can open the 'debuginfo.txt' file from a text editor and have a look
+
+--------------------------
+Windows binary generation
+-------------------------
+It should be possible f you compile under windows
+using Visual C++. Please read the HOWTO_VisualCpp for details
+
+I compile under linux all windows binaries, using gcc that generates
+windows executables. It works really well. There is a sort-of-howto in
+the "HOWTO_MinGW32" text file. A short step-by-step is here:
+
+1) Install gcc that generates windows binaries:
+
+i586-mingw32msvc
+
+2) Install all libraries (libz)
+
+3) Get "libz" from source and compile as per "HOWTO_MINGW32"

+ 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.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+// Mersenne Twister random number generator -- a C++ class MTRand
+// Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus
+// Richard J. Wagner v1.0 15 May 2003 rjwagner@writeme.com
+
+// The Mersenne Twister is an algorithm for generating random numbers. It
+// was designed with consideration of the flaws in various other generators.
+// The period, 2^19937-1, and the order of equidistribution, 623 dimensions,
+// are far greater. The generator is also fast; it avoids multiplication and
+// division, and it benefits from caches and pipelines. For more information
+// see the inventors' web page at http://www.math.keio.ac.jp/~matumoto/emt.html

+// Change log:
+//
+// v0.1 - First release on 15 May 2000
+// - Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus
+// - Translated from C to C++
+// - Made completely ANSI compliant
+// - Designed convenient interface for initialization, seeding, and
+// obtaining numbers in default or user-defined ranges
+// - Added automatic seeding from /dev/urandom or time() and clock()
+// - Provided functions for saving and loading generator state
+//
+// v0.2 - Fixed bug which reloaded generator one step too late
+//
+// v0.3 - Switched to clearer, faster reload() code from Matthew Bellew
+//
+// v0.4 - Removed trailing newline in saved generator format to be consistent
+// with output format of built-in types
+//
+// v0.5 - Improved portability by replacing static const int's with enum's and
+// clarifying return values in seed(); suggested by Eric Heimburg
+// - Removed MAXINT constant; use 0xffffffffUL instead
+//
+// v0.6 - Eliminated seed overflow when uint32 is larger than 32 bits
+// - Changed integer [0,n] generator to give better uniformity
+//
+// v0.7 - Fixed operator precedence ambiguity in reload()
+// - Added access for real numbers in (0,1) and (0,n)
+//
+// v0.8 - Included time.h header to properly support time_t and clock_t
+//
+// v1.0 - Revised seeding to match 26 Jan 2002 update of Nishimura and Matsumoto
+// - Allowed for seeding with arrays of any length
+// - Added access for real numbers in [0,1) with 53-bit resolution
+// - Added access for real numbers from normal (Gaussian) distributions
+// - Increased overall speed by optimizing twist()
+// - Doubled speed of integer [0,n] generation
+// - Fixed out-of-range number generation on 64-bit machines
+// - Improved portability by substituting literal constants for long enum's
+// - Changed license from GNU LGPL to BSD

+ Martin Maurer
+* Cache cleaning is finally fixed
+* Disabling part-finding as it made us loose 3+ points at SAT Comp'11
+* Clauses after empty comments sometimes weren't parsed. Thanks to Remy Delmas
+ for noticing this
+* Solutions were sometimes incorrect when using --maxsolutions=X
+* Random variable picking was turned off after a short while. Thanks to
+ Martin Maurer for noticing this
+* XOR-to-normal clause converting routine was buggy
+* Failed literal probing's hyper-binary resolution engine was taking too
+ much time
+* Performance regressions relative to branch that went into SatComp'11
+ have been worked on
+* FPU check problem fixed thanks to Jerry James
+* Printing problems related to multi-threading and startup in Main.cpp
+ fixed. Thanks to Martin Maurer for reporting this.
+
+Improvements:
+* Manpage thanks to Jerry James
+* We don't exit(-1) any more, instead, whe throw. Thanks to Jerry James for
+ this
+* Time-limiting in subsumption+strengthening+var-elim was not sufficient
+* "strengthened" qualifier removed from Clause
+* Way better subsumption+strengthening with 2- and 3-long clauses.
+* Cache cleaning
+
+ver 2.9.1 26/05/2011
+* Subsumption is now in one go instead handling learnt&non-learnt in different
+ runs.
+* Hyper-bin resolution is fixed(?). The algorithm has become too complex to
+ tell if it's correct -- a complete rewrite will be made for the next version
+* Lots of Gaussian bugs have been fixed -- thanks go to Vegard Nossum
+* A lot of compilation issues have been fixed to the point that the program
+ now compiles with "-pedantic -Wall -Werror" on many different systems.
+ Thanks for this go to: Martin Albrecht, Robert Aston, Martin Maurer, Vegard
+ Nossum and others on the CryptoMiniSat mailing list
+
+ver 2.9.0 20/01/2011
+* Added extended SCC and vivification using cached implications
+* Reachability testing and related branching heuristic using cached
+ implications
+* Corrected subsumption code -- it is now more precise but slower
+* Corrected original problem & learnt dumping. Binary clauses were wrongly
+ dumped, and xor clauses were never dumped
+* Better time-limiting on subsumption, var-elimination, etc.
+* When a variable can be eliminated with no resulting clauses, it is elim-ed
+* On-the-fly transitive self-subsuming resolution is now carried out based
+ on short/long-term average clause sizes and glue numbers
+* More stats are printed. CPU times in stats are better in case a recent
+ (>2.6.26) version of the Linux kernel is used.
+* Multi-threaded solving is no longer default since it hasn't been really
+ tested in terms of performance
+* Lots of debug code is now enabled by default. It slows down things by
+ maybe 5% but keeps the code more sane
+* gcc bug 47365 has been found and workaround is automated through the
+ configure script. If you build using hand-crafted Makefiles, you will bump
+ into this bug for sure.
+
+ver 2.8.0beta5 2/11/2010
+* reason[] was taken to be correct, when in fact it is not updated during
+ canceling
+* Subsumer::unEliminate() erased iterators from std::map that was not inside
+ the map
+
+ver 2.8.0beta4 31/10/2010
+* class Watched is now tuned more towards operations that are executed
+ more. These now require no bit-shifting
+* Bug fix: debug code left in from DimacsParser removed
+
+ver 2.8.0beta3 30/10/2010
+* Bug in hand-coded Tarjan's algorithm. We were manipulating the watchlists
+ while using them. This lead to a segfault.
+* Bug in replace() -- we were using replace(), but the clauses were not always
+ attached (e.g. in ClauseDetacherReattacher) and so the added binary clause
+ was not always l_Undef,l_Undef. A very subtle bug that could have caused
+ solution-sanity problems
+* Fixed bug with opening fileno(stdin)
+
+ver 2.8.0beta2 28/10/2010
+* Boost dependency removed through implementation of Tarjan's algorithm by
+ hand. This also implies a much reduced memory footprint in case there were
+ many binary clauses
+
+ver 2.8.0beta1 27/10/2010
+* Binary clauses are now implicit. This allows for _very_ large problems
+ that contain mostly only binary clauses to work surprisingly well in terms
+ of subsumption and self-subsuming resolution. Also, variable elimination
+ should now be possible for these clauses (been tested problem with 120
+ million binary clauses)
+* Due to implicit binary clauses, we use Tarjan's algorithm, currently
+ from Boost -- this dependency will be removed soon
+* A preliminary multi-threading is possible. Unitary and binary clauses are
+ shared between the threads at regular intervals. Threading is with OpenMP
+ which should be available for all platforms
+* Lots and lots of bugfixes. On many occasions, clauses and xor-clauses have
+ been inserted into the watchlists when these clauses' variables were
+ fixed, leading to some very bad effects.
+
+ver 2.7.1 -- 10/10/2010
+* Bug in DIMACS-parsing fixed. We couldn't read back the dumped clauses'
+ learnt state properly, which lead to parsing problems. Thanks to
+ Vlastislav Weiner for reporting this
+
+ver 2.7.0 -- 5/10/2010
+* Lots of documentation added. At least 1500 lines of in-line documentation
+ is now available. This documentation can be extracted using the Doxygen
+ tool
+* Transitive on-the-fly self-subsuming resolution added for short clauses
+ at the beginning of the solving (<80 million conflict literals).
+* Preliminary learnt-clause parsing -- the dumped learnt clauses are now
+ correctly parsed up to be learnt, and hence a preliminary of stop-
+ solving & restart-solving cycle can be created
+* Memory manager has been debugged. It was segfaulting on certain large
+ instances. (thanks to Rob None for the multiple bug reports)
+* Memory manager no longer needs to keep a map of old clauses<-> new
+ clauses. This is now a direct-access table, speeding up memory
+ consolidation considerably
+
+ver 2.6.0 -- 16/08/2010
+* No more separate watchlists for binary clauses. Class "Watched" knows
+ what it watches. This reduces memory overhead, and reduces jump-around
+ in code and data.
+* Tertiary clauses are handled natively inside the watchlists just like
+ binary clauses
+* Watchlists are sorted to propagate binary clauses first, and tertiary
+ clauses next, finally to propagate normal and xor clauses
+* Clause subsumption has finally been cleared of a number of bugs. We now
+ subsume with learnt clauses on a regular basis.
+* 32-bit pointers are no longer used. Instead, a stack-based implementation
+ is used, on the lines of the description of the solver lingeling by
+ Armin Biere. This leads to minimal (~6%) speedup relative to the original
+ scheme in CryptoMiniSat 2.5.1, but it enables 32-bit pointers on all
+ architectures
+* Asymmetric branching is now used. Clauses are sorted according to size,
+ and the largest ones are shortened with asymm-branching. This brings
+ large benefits, as often the largest clauses are responsible for a good
+ number of the literals in the learnt clauses. Asymmetric branching thus
+ reduces the learnt clause sizes, increasing their potential and making
+ propagation faster
+* On-the-fly self-subsuming resolution of learnt clauses is used to
+ shorten them even further using binary and tertiary (i.e. natively
+ stored) clauses.
+* Since tertiary clauses are first to propagate after binary clauses, the
+ number of tertiary clauses propagating is higher, leading to even less
+ literals in the learnt clauses
+* Printing has been updated. It is still not perfect, but we are making
+ progress.
+* Known regressions: xor clauses could potentially be propagated somewhat
+ slower, statistics generator is currently broken
+
+ver 2.5.2 -- 8/06/2010
+* Fixing serious bug with xor-cutting. We no longer segfault if there are
+ many XORs in the given problem
+
+ver 2.5.1 -- 8/06/2010 --- 'The Obvious Child'
+* Printing updates: everyting is printed much more nicely now
+* Approximated degrees of literals in binary graph are not reset between
+ calculations
+
+ver 2.5.0 -- 7/06/2010 (SAT Race'10 version)
+* A lot of performance bugs have been fixed. Activities of clauses were wrongly
+ updated with their abstract representation during subsumtion for example.
+ Also, we now use a well-tested set of magic constants instead of making
+ them up using intuition. Apparently, intuition in the field of SAT leads
+ to headaches and (in severe cases) to dementia.
+* A lot of code has been added regarding binary clause graphs. It is now
+ regularly cleaned from useless binary clauses. Also, the useless binary
+ clauses are regularly generated to subsume and strenghthen other clauses
+ with them -- and once used, these useless binary clauses are thrown away.
+* Hyper-binary clauses are now generated using an algorithm relying purely
+ on the datastrucures available in modern SAT solvers -- i.e. the fact that
+ binary clauses have their own watchlists, and so allow for efficient
+ propagation of the binary clauses separately from other clauses.
+
+ver 2.4.2 -- 9/05/2010
+* Gaussian elimination has finally been fixed. It can now be tried out with
+ the command-line switch "--gaussuntil=X", where X is the maximum depth. I
+ usually set 100, but this is probably a wrong default. You should experiment
+ with your own cipher. NOTE: Gauss is still experimental. If it segfaults,
+ please file a bug.
+* The solver can now print out all the solutions to a problem. Simply use the
+ "--maxsolutions=X" option, where X is the maximum number of solutions you
+ need. You may use this option in conjunction with the very experimental
+ "--greedyunbound" which unassigns some variables in such a way that the
+ given solution is still correct, but some variables may not appear in it.
+* Command line switches have been corrected. They are now all lower-case and
+ use the prefix "--" instead of "-"
+
+ver 2.4.1 -- 30/04/2010
+Serious bug fixed that read data from change memory in subsume0, and
+hyper-binary resolution has been disabled, since it caused satisfiable
+instances to become unsatisfiable.
+
+ver 2.4.0 -- 26/04/2010
+The first real release of CryptoMiniSat v2. It contains the following set
+of improvements:
+ * XOR clauses are extracted at the beginning of the solving
+ * Anti- or equivalent variables are detected at regular intervals
+ and are replaced with one another, eliminating variables during
+ solving
+ * xor-clauses are regularly XOR-ed with one another such as to obtain
+ binary XOR clauses. These binary xor-clauses are then treated as variable
+ replacements instructions (i.e. "v1 XOR v2 = false" means that v1 is
+ replaced with v2)
+ * Phase calculation using Jeroslow and Wang, and phase saving with
+ randomised search space exploration. The average branch depth is
+ measured for each instance, and the solver makes a random phase
+ flip with 1/avgBranchDepth probability
+ * Random search burst are used to search unexplored areas of the
+ search space at regular intervals
+ * Automatic detection of cryptographic and industrial instances. Dynamic
+ restart is used for industrial instances, and static restart for
+ cryptographical instances. Detection is based on xor-clause percentage
+ and variable activity stability.
+ * Regular full restarts are performed to detect if the problem hasn't
+ changed enough due to learnt clauses and assigned variables to behave
+ more like a cryptographical instance than an industrial instance or
+ vice-versa.
+ * Both GLUCOSE-type learnt clause activity and MiniSat-type learnt clause
+ activity heuristics are supported. During dynamic restarts, the GLUCOSE
+ heuristic is used, while during static restarts, the MiniSat-type
+ heuristic is used.
+ * SatELite-type variable elimination, clause subsumption and clause
+ strengthening is regularly performed. The occurrence lists are, however,
+ not updated all the time such as the case is with PrecoSat. Instead,
+ occurrences are calculated on per-use basis
+ * On-the-fly subsumption is used to check whether the conflict clause
+ automatically subsumes the clause that caused the conflict.
+ * Binary clauses are propagated first before non-binary clauses are
+ propagated.
+ * 32-bit pointers are used for the watchlists on 64-bit architectures,
+ using out the fact that most bits in the 64-bit pointer are actually fixed
+ * Hyper-binary resolution is used when the hyper-binary clause subsumes
+ any of the original clauses
+ * Clauses are regularly scrubbed from variables that have been assigned
+ * Preliminary blocked-clause elimination is used to remove pure literals
+ * Distinct subproblems are regularly searched for and detected. These
+ subproblems and solved with subsolvers. As a side-ntoe, this eliminates
+ the original theoretical need for phase-saving (enabling the random
+ flipping of phase, which is also used)
+ * xor-clause subsumption is regularly performed
+ * So-called dependent variables are removed along with their xor-clauses.
+ This means that variables that only occur in one xor-clause and in no
+ other clause are removed along with the XOR clause. Once the solving has
+ finished, this xor-clause is re-introduced and a suitable value for the
+ variable is found to satisfy the XOR.
+ * Failed variable probing with both-propagated and binary XOR detection.
+ All variables are successively propagated both to TRUE and FALSE. If one
+ of these branches fails, the variable is assigned the other branch.
+ If none fails, but the intersection of assignments is non-empty, those
+ assignments are made. Essentially the same is done to non-binary XOR-s:
+ if both v and !v propagate a given binary XOR, that XOR is learnt.
+ * Designed to work as a library and as a drop-in replacement for MiniSat
+
+ver 2.3.2 -- 28/12/2009
+* further ints have been replaced with uints
+* ZLIB can now be disabled
+* Visual C++ 2008 can now compile the sources
+* Statistics generation is much faster
+ (thanks to Martin Maurer for spotting this)
+
+ver 2.3.0 -- 17/12/2009
+* binary learnts are converted to 2-long xors if possible, and eliminated
+* lots of heuristics tuning
+* Cleanclauses is now default instead of removeSatisfied in simplify()
+* Stable in case used as a library
+* Lots of regression tests added
+* Cleaner logging
+* ints have been replaced with uints (less warnings with -Wall)
+* a lot of speedups for gauss -- packed, multi-matrix representation
+
+ver 2.2 -- 20/11/2009
+* xor-clause finding
+* matrix finding
+* var-replacing

+* don't allow too long group and variable names
+* branch length distribution added

+******************
+** XOR clauses ***
+******************
+If you want to express a xor, e.g.
+
+"var1 + var2 + !var3 = true"
+
+then you simply need to put into the CNF file the line:
+
+"x1 2 -3 0"
+
+The "x" in front of the line means that this is a xor-clause clause.
+
+
+*************************************
+** custom branching variable order **
+*************************************
+The CNF input may contain lines of the form:
+
+ b 3 4 17 0
+ b 10 0
+
+This means that the solver will try to branch on the variables 3, 4, 17,
+and 10, in that particular order, before branching on any other variables.
+Remaining (unspecified) variables will use the regular variable selection
+heuristic.

+@author Mate Soos, and collaborators
+
+CryptoMiniSat is an award-winning SAT solver based on MiniSat. It brings a
+number of benefits relative to MiniSat, among them XOR clauses, extensive
+failed literal probing, and better random search.
+
+The solver basically performs the following steps:
+
+1) parse CNF file into clause database
+
+2) run Conflict-Driven Clause-Learning DPLL on the clauses
+
+3) regularly run simplification passes on the clause-set
+
+4) display solution and if not used as a library, exit
+
+Here is a picture of of the above process in more detail:

+@brief Handles xor-subsumption and variable elimination at the XOR level
+
+This class achieves three things:
+
+1) it removes variables though XOR-ing of two xors thereby removing their common
+variable. If that variable is not used anywere else, the variable is now removed
+from the problem
+
+2) It tries to XOR clauses together to get 1-long or 2-long XOR clauses. These
+force variables to certain values or replace variables with other variables,
+respectively
+
+3) It tries to subsume XOR clauses with other XOR clauses (making 2 XOR clauses
+in the process, but one of them is going to be much smaller than it was originally)

+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)

+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#

+\`configure' configures cryptominisat 2.9.2 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CXX C++ compiler command
+ CXXFLAGS C++ compiler flags
+ CXXCPP C++ preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.TH "CRYPTOMINISAT" "1" "@VERSION@" "Mate Soos" "User Commands"
+.SH "NAME"
+cryptominisat \- conflict-driven SAT solver
+.SH "SYNOPSIS"
+.B cryptominisat
+[\fIOPTIONS\fP] <\fIinput\-file\fP> <\fIoutput\-file\fP>
+.SH "DESCRIPTION"
+.PP
+CryptoMiniSat is a SAT solver, solving problems given in CNF, or conjunctive
+normal form. CryptoMiniSat retains much of the API of MiniSat, but
+offers more versatility and better speed on many problems.
+
+The program is a classical conflict-driven solver, with variable activities,
+clause learning and clause deletion. It however incorporates a number of
+advanced CNF simplification functionalities which should help the speed of
+solving. Further, it incorporates some advanced memory-management features
+that should help in getting the most out of modern CPU caches.
+
+The input format is that of DIMACS CNF, i.e. a header of the form
+
+p cnf VARS CLAUSES
+
+where VARS is the number of variables, and CLAUSES is the number of clauses in
+the problem. It then lists the set of clauses such as:
+
+1 -2 0
+
+which is equivalent to the 2-long clause "v1 OR NOT v2 = TRUE"
+
+.SH "OPTIONS"
+.TP
+\fB\-\-polarity\-mode\fP = \fI{true,false,rnd,auto}\fP [default: auto]
+Selects the polarity mode. Auto is the Jeroslow&Wang method.
+.TP
+\fB\-\-rnd\-freq\fP = <\fInum\fP> [0-1] How often should decision variables
+be picked randomly.
+.TP
+\fB\-\-verbosity\fP = <\fInum\fP> [0-2] Verbosity 1 is default. Verbosity 0
+only prints the results, and verbosity 2 prints many useful debug info.
+.TP
+\fB\-\-randomize\fP = <\fIseed\fP> [0 - 2^32-1]
+Sets the random seed, used for picking decision variables (default = 0).
+.TP
+\fB\-\-restrict\fP = <\fInum\fP> [1 - varnum]
+When picking random variables to branch on, pick one that is in the \fInum\fP
+most active vars useful for cryptographic problems, where the question is the
+key, which is usually small (e.g., 80 bits).
+.TP
+\fB\-\-gaussuntil\fP = <\fInum\fP>
+Depth until which Gaussian elimination is active. Giving 0 switches off
+Gaussian elimination.
+.TP
+\fB\-\-restarts\fP = <\fInum\fP> [1 - 2^32-1]
+No more than the given number of restarts will be performed during search.
+.TP
+\fB\-\-nonormxorfind\fP
+Don't find and collect >2-long xor-clauses from regular clauses.
+.TP
+\fB\-\-nobinxorfind\fP
+Don't find and collect 2-long xor-clauses from regular clauses.
+.TP
+\fB\-\-noregbxorfind\fP
+Don't regularly find and collect 2-long xor-clauses from regular clauses.
+.TP
+\fB\-\-doextendedscc\fP
+Do strongly connected component finding using non-existent binary clauses.
+Makes binary XOR findig slower, but somewhat more accurate.
+.TP
+\fB\-\-noconglomerate\fP
+Don't conglomerate 2 xor clauses when one var is dependent. This allows for
+elimination of variable y if it is only in the two XOR clauses "y XOR a XOR b" and
+"y XOR c XOR d"
+.TP
+\fB\-\-nosimplify\fP
+Don't do regular simplification rounds. These simplification rounds greatly
+simplify the CNF, but cost time. If your problem is very small, it may be
+only a waste of time to execute these simplification rounds. Typically, however,
+these simplification methods save significant amount of time (>60%)
+.TP
+\fB\-\-greedyunbound\fP
+Greedily unbound variables that are not needed for the final satisfying
+assignement.
+.TP
+\fB\-\-debuglib\fP
+Solve at specific \fBc Solver::solve()\fP points in the CNF file. Used to
+debug file generated by Solver's \fBneedLibraryCNFFile()\fP function.
+.TP
+\fB\-\-debugnewvar\fP
+Add new vars at specific \fBc Solver::newVar()\fP points in the CNF file.
+Used to debug file generated by Solver's \fBneedLibraryCNFFile()\fP function.
+.TP
+\fB\-\-novarreplace\fP
+Don't perform variable replacement. Needed for programmable solver feature.
+.TP
+\fB\-\-restart\fP = \fI{auto, static, dynamic}\fP
+Which kind of restart strategy to follow. Default is \fIauto\fP.
+.TP
+\fB\-\-dumplearnts\fP = <\fIfilename\fP>
+If interrupted or reached restart limit, dump the learnt clauses to the
+specified file. Maximum size of dumped clauses can be specified with the
+\fB\-\-maxdumplearnts\fP option.
+.TP
+\fB\-\-maxdumplearnts\fP = [0 - 2^32-1]
+When dumping the learnts to file, what should be maximum length of the clause
+dumped. Useful to make the resulting file smaller. Default is 2^32-1. Note:
+2-long XORs are always dumped.
+.TP
+\fB\-\-dumporig\fP = <\fIfilename\fP>
+If interrupted or reached restart limit, dump the original problem instance,
+simplified to the current point.
+.TP
+\fB\-\-alsoread\fP = <\fIfilename\fP>
+Also read this file in. Can be used to re-read dumped learnts, for example.
+.TP
+\fB\-\-maxsolutions\fP = <\fInum\fP>
+Search for given amount of solutions. Can only be used in single-threaded
+mode (\fB--threads=1\fP).
+.TP
+\fB\-\-pavgbranch\fP
+Print average branch depth.
+.TP
+\fB\-\-nofailedlit\fP
+Don't search for failed literals, and don't search for literals propagated
+both by \fIvarX\fP and \fI-varX\fP.
+.TP
+\fB\-\-noheuleprocess\fP
+Don't try to minimise XORs by XOR-ing them together. Algorithm as per
+global/local substitution in Heule's thesis.
+.TP
+\fB\-\-nosatelite\fP
+Don't do clause subsumption, clause strengthening and variable elimination
+(implies \fB\-\-novarelim\fP and \fB\-\-nosubsume1\fP).
+.TP
+\fB\-\-noxorsubs\fP
+Don't try to subsume xor-clauses.
+.TP
+\fB\-\-nosolprint\fP
+Don't print the satisfying assignment if the solution is SAT.
+.TP
+\fB\-\-novarelim\fP
+Don't perform variable elimination as per Een and Biere.
+.TP
+\fB\-\-nosubsume1\fP
+Don't perform clause contraction through resolution.
+.TP
+\fB\-\-noparthandler\fP
+Don't find and solve subroblems with subsolvers.
+.TP
+\fB\-\-nomatrixfind\fP
+Don't find distinct matrixes. Put all xors into one big matrix.
+.TP
+\fB\-\-noordercol\fP
+Don't order variables in the columns of Gaussian elimination. Effectively
+disables iterative reduction of the matrix.
+.TP
+\fB\-\-noiterreduce\fP
+Don't reduce iteratively the matrix that is updated.
+.TP
+\fB\-\-maxmatrixrows\fP = [0 - 2^32-1]
+Set maximum number of rows for gaussian matrix. Too large matrixes should be
+discarded for reasons of efficiency. Default: 1000.
