-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>.

-// MersenneTwister.h
-// 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

-ver 2.9.2 22/01/2011
-Bugfixes:
-* Bug in --maxsolutions fixed thanks to Martin Maurer
-* CalcDefPolars was taking >10% time for certain problems. Fixed thanks to
- Vegard Nossum
-* Bug in StateSaver of saving&restoring double to unsigned fixed thanks to
- 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

-******************
-** 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 Chooses between MiniSat and GLUCOSE restart types&learnt clause evaluation
-
-MiniSat style restart is geometric, and glucose-type is dynamic. MiniSat-type
-learnt clause staistic is activity-based, glucose-type is glue-based. This
-class takes as input a number of MiniSat restart's end results, computes some
-statistics on them, and at the end, tells if we should use one type or the
-other. Basically, it masures variable activity stability, number of xors
-in the problem, and variable degrees.

-@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)

-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# 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
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-# 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.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.

-\`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:

- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]
- --enable-fast-install[=PKGS]
- optimize for fast installation [default=yes]
- --disable-libtool-lock avoid locking (might break parallel builds)
- --enable-static-link Enable static linking (off by default)
- --disable-dependency-tracking speeds up one-time build
- --enable-dependency-tracking do not reject slow dependency extractors
- --disable-openmp do not use OpenMP
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
- --with-sysroot=DIR Search for dependent libraries within DIR
- (or the compiler's sysroot if not specified).
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- 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.
-
-Report bugs to the package provider.

-.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.
-.TP
-\fB\-\-minmatrixrows\fP = [0 - 2^32-1]
-Set minimum number of rows for gaussian matrix. Normally, too small matrixes
-are discarded for reasons of efficiency. Default: 20.
-.TP
-\fB\-\-savematrix\fP = [0 - 2^32-1]

-.TP
-\fB\-\-nohyperbinres\fP
-Don't add binary clauses when doing failed lit probing.
-.TP
-\fB\-\-noremovebins\fP
-Don't remove useless binary clauses.
-.TP
-\fB\-\-noremlbins\fP
-Don't remove useless learnt binary clauses.
-.TP
-\fB\-\-nosubswithbins\fP
-Don't subsume with binary clauses.
-.TP
-\fB\-\-nosubswithnbins\fP
-Don't subsume with non-existent binary clauses.
-.TP
-\fB\-\-noclausevivif\fP
-Don't perform clause vivification.
