+                    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>.

-  CeCILL FREE SOFTWARE LICENSE AGREEMENT
-
-Version 2.1 dated 2013-06-21
-
-
-    Notice
-
-This Agreement is a Free Software license agreement that is the result
-of discussions between its authors in order to ensure compliance with
-the two main principles guiding its drafting:
-
-  * firstly, compliance with the principles governing the distribution
-    of Free Software: access to source code, broad rights granted to users,
-  * secondly, the election of a governing law, French law, with which it
-    is conformant, both as regards the law of torts and intellectual
-    property law, and the protection that it offers to both authors and
-    holders of the economic rights over software.
-
-The authors of the CeCILL (for Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre]) 
-license are: 
-
-Commissariat à l'énergie atomique et aux énergies alternatives - CEA, a
-public scientific, technical and industrial research establishment,
-having its principal place of business at 25 rue Leblanc, immeuble Le
-Ponant D, 75015 Paris, France.
-
-Centre National de la Recherche Scientifique - CNRS, a public scientific
-and technological establishment, having its principal place of business
-at 3 rue Michel-Ange, 75794 Paris cedex 16, France.

-
-    Preamble
-
-The purpose of this Free Software license agreement is to grant users
-the right to modify and redistribute the software governed by this
-license within the framework of an open source distribution model.
-
-The exercising of this right is conditional upon certain obligations for
-users so as to preserve this status for all subsequent redistributions.
-
-In consideration of access to the source code and the rights to copy,
-modify and redistribute granted by the license, users are provided only
-with a limited warranty and the software's author, the holder of the
-economic rights, and the successive licensors only have limited liability.
-
-In this respect, the risks associated with loading, using, modifying
-and/or developing or reproducing the software by the user are brought to
-the user's attention, given its Free Software status, which may make it
-complicated to use, with the result that its use is reserved for
-developers and experienced professionals having in-depth computer
-knowledge. Users are therefore encouraged to load and test the
-suitability of the software as regards their requirements in conditions
-enabling the security of their systems and/or data to be ensured and,
-more generally, to use and operate it in the same conditions of
-security. This Agreement may be freely reproduced and published,
-provided it is not altered, and that no provisions are either added or
-removed herefrom.
-
-This Agreement may apply to any or all software for which the holder of
-the economic rights decides to submit the use thereof to its provisions.

-least by this Agreement, for the duration set forth in Article 4.2 <#term>.
-
-
-      6.2 OVER THE CONTRIBUTIONS

-
-
-      6.4 JOINT PROVISIONS
-
-The Licensee expressly undertakes:
-
- 1. not to remove, or modify, in any manner, the intellectual property
-    notices attached to the Software;

-    the Software modified or not.
-
-The Licensee undertakes not to directly or indirectly infringe the
-intellectual property rights on the Software of the Holder and/or
-Contributors, and to take, where applicable, vis-à-vis its staff, any
-and all measures required to ensure respect of said intellectual
-property rights of the Holder and/or Contributors.
-
-
-    Article 7 - RELATED SERVICES
-
-7.1 Under no circumstances shall the Agreement oblige the Licensor to
-provide technical assistance or maintenance services for the Software.
-
-However, the Licensor is entitled to offer this type of services. The
-terms and conditions of such technical assistance, and/or such
-maintenance, shall be set forth in a separate instrument. Only the
-Licensor offering said maintenance and/or technical assistance services
-shall incur liability therefor.
-
-7.2 Similarly, any Licensor is entitled to offer to its licensees, under
-its sole responsibility, a warranty, that shall only be binding upon
-itself, for the redistribution of the Software and/or the Modified
-Software, under terms and conditions that it is free to decide. Said
-warranty, and the financial terms and conditions of its application,
-shall be subject of a separate instrument executed between the Licensor
-and the Licensee.
-
-
-    Article 8 - LIABILITY
-
-8.1 Subject to the provisions of Article 8.2, the Licensee shall be
-entitled to claim compensation for any direct loss it may have suffered
-from the Software as a result of a fault on the part of the relevant
-Licensor, subject to providing evidence thereof.
-
-8.2 The Licensor's liability is limited to the commitments made under
-this Agreement and shall not be incurred as a result of in particular:
-(i) loss due the Licensee's total or partial failure to fulfill its
-obligations, (ii) direct or consequential loss that is suffered by the
-Licensee due to the use or performance of the Software, and (iii) more
-generally, any consequential loss. In particular the Parties expressly
-agree that any or all pecuniary or business loss (i.e. loss of data,
-loss of profits, operating loss, loss of customers or orders,
-opportunity cost, any disturbance to business activities) or any or all
-legal proceedings instituted against the Licensee by a third party,
-shall constitute consequential loss and shall not provide entitlement to
-any or all compensation from the Licensor.
-
-
-    Article 9 - WARRANTY
-
-9.1 The Licensee acknowledges that the scientific and technical
-state-of-the-art when the Software was distributed did not enable all
-possible uses to be tested and verified, nor for the presence of
-possible defects to be detected. In this respect, the Licensee's
-attention has been drawn to the risks associated with loading, using,
-modifying and/or developing and reproducing the Software which are
-reserved for experienced users.
-
-The Licensee shall be responsible for verifying, by any or all means,
-the suitability of the product for its requirements, its good working
-order, and for ensuring that it shall not cause damage to either persons
-or properties.
-
-9.2 The Licensor hereby represents, in good faith, that it is entitled
-to grant all the rights over the Software (including in particular the
-rights set forth in Article 5 <#scope>).
-
-9.3 The Licensee acknowledges that the Software is supplied "as is" by
-the Licensor without any other express or tacit warranty, other than
-that provided for in Article 9.2 <#good-faith> and, in particular,
-without any warranty as to its commercial value, its secured, safe,
-innovative or relevant nature.
-
-Specifically, the Licensor does not warrant that the Software is free
-from any error, that it will operate without interruption, that it will
-be compatible with the Licensee's own equipment and software
-configuration, nor that it will meet the Licensee's requirements.
-
-9.4 The Licensor does not either expressly or tacitly warrant that the
-Software does not infringe any third party intellectual property right
-relating to a patent, software or any other property right. Therefore,
-the Licensor disclaims any and all liability towards the Licensee
-arising out of any or all proceedings for infringement that may be
-instituted in respect of the use, modification and redistribution of the
-Software. Nevertheless, should such proceedings be instituted against
-the Licensee, the Licensor shall provide it with technical and legal
-expertise for its defense. Such technical and legal expertise shall be
-decided on a case-by-case basis between the relevant Licensor and the
-Licensee pursuant to a memorandum of understanding. The Licensor
-disclaims any and all liability as regards the Licensee's use of the
-name of the Software. No warranty is given as regards the existence of
-prior rights over the name of the Software or as regards the existence
-of a trademark.
-
-
-    Article 10 - TERMINATION
-
-10.1 In the event of a breach by the Licensee of its obligations
-hereunder, the Licensor may automatically terminate this Agreement
-thirty (30) days after notice has been sent to the Licensee and has
-remained ineffective.
-
-10.2 A Licensee whose Agreement is terminated shall no longer be
-authorized to use, modify or distribute the Software. However, any
-licenses that it may have granted prior to termination of the Agreement
-shall remain valid subject to their having been granted in compliance
-with the terms and conditions hereof.
-
-
-    Article 11 - MISCELLANEOUS
-
-
-      11.1 EXCUSABLE EVENTS
-
-Neither Party shall be liable for any or all delay, or failure to
-perform the Agreement, that may be attributable to an event of force
-majeure, an act of God or an outside cause, such as defective
-functioning or interruptions of the electricity or telecommunications
-networks, network paralysis following a virus attack, intervention by
-government authorities, natural disasters, water damage, earthquakes,
-fire, explosions, strikes and labor unrest, war, etc.
-
-11.2 Any failure by either Party, on one or more occasions, to invoke
-one or more of the provisions hereof, shall under no circumstances be
-interpreted as being a waiver by the interested Party of its right to
-invoke said provision(s) subsequently.
-
-11.3 The Agreement cancels and replaces any or all previous agreements,
-whether written or oral, between the Parties and having the same
-purpose, and constitutes the entirety of the agreement between said
-Parties concerning said purpose. No supplement or modification to the
-terms and conditions hereof shall be effective as between the Parties
-unless it is made in writing and signed by their duly authorized
-representatives.
-
-11.4 In the event that one or more of the provisions hereof were to
-conflict with a current or future applicable act or legislative text,
-said act or legislative text shall prevail, and the Parties shall make
-the necessary amendments so as to comply with said act or legislative
-text. All other provisions shall remain effective. Similarly, invalidity
-of a provision of the Agreement, for any reason whatsoever, shall not
-cause the Agreement as a whole to be invalid.
-
-
-      11.5 LANGUAGE
-
-The Agreement is drafted in both French and English and both versions
-are deemed authentic.
-
-
-    Article 12 - NEW VERSIONS OF THE AGREEMENT
-
-12.1 Any person is authorized to duplicate and distribute copies of this
-Agreement.
-
-12.2 So as to ensure coherence, the wording of this Agreement is
-protected and may only be modified by the authors of the License, who
-reserve the right to periodically publish updates or new versions of the
-Agreement, each with a separate number. These subsequent versions may
-address new issues encountered by Free Software.
-
-12.3 Any Software distributed under a given version of the Agreement may
-only be subsequently distributed under the same version of the Agreement
-or a subsequent version, subject to the provisions of Article 5.3.4
-<#compatibility>.
-
-
-    Article 13 - GOVERNING LAW AND JURISDICTION
-
-13.1 The Agreement is governed by French law. The Parties agree to
-endeavor to seek an amicable solution to any disagreements or disputes
-that may arise during the performance of the Agreement.
-
-13.2 Failing an amicable solution within two (2) months as from their
-occurrence, and unless emergency proceedings are necessary, the
-disagreements or disputes shall be referred to the Paris Courts having
-jurisdiction, by the more diligent Party.

-entre ses auteurs afin que le respect de deux grands principes préside à
-sa rédaction:
-
-  * d'une part, le respect des principes de diffusion des logiciels
-    libres: accès au code source, droits étendus conférés aux utilisateurs,
-  * d'autre part, la désignation d'un droit applicable, le droit
-    français, auquel elle est conforme, tant au regard du droit de la
-    responsabilité civile que du droit de la propriété intellectuelle et
-    de la protection qu'il offre aux auteurs et titulaires des droits
-    patrimoniaux sur un logiciel.
-
-Les auteurs de la licence CeCILL (Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre])

-
-    Préambule
-
-Ce contrat est une licence de logiciel libre dont l'objectif est de
-conférer aux utilisateurs la liberté de modification et de
-redistribution du logiciel régi par cette licence dans le cadre d'un
-modèle de diffusion en logiciel libre.
-
-L'exercice de ces libertés est assorti de certains devoirs à la charge
-des utilisateurs afin de préserver ce statut au cours des
-redistributions ultérieures.
-
-L'accessibilité au code source et les droits de copie, de modification
-et de redistribution qui en découlent ont pour contrepartie de n'offrir
-aux utilisateurs qu'une garantie limitée et de ne faire peser sur
-l'auteur du logiciel, le titulaire des droits patrimoniaux et les
-concédants successifs qu'une responsabilité restreinte.
-
-A cet égard l'attention de l'utilisateur est attirée sur les risques
-associés au chargement, à l'utilisation, à la modification et/ou au
-développement et à la reproduction du logiciel par l'utilisateur étant
-donné sa spécificité de logiciel libre, qui peut le rendre complexe à
-manipuler et qui le réserve donc à des développeurs ou des
-professionnels avertis possédant des connaissances informatiques
-approfondies. Les utilisateurs sont donc invités à charger et tester
-l'adéquation du logiciel à leurs besoins dans des conditions permettant
-d'assurer la sécurité de leurs systèmes et/ou de leurs données et, plus
-généralement, à l'utiliser et l'exploiter dans les mêmes conditions de
-sécurité. Ce contrat peut être reproduit et diffusé librement, sous
-réserve de le conserver en l'état, sans ajout ni suppression de clauses.
-
-Ce contrat est susceptible de s'appliquer à tout logiciel dont le
-titulaire des droits patrimoniaux décide de soumettre l'exploitation aux
-dispositions qu'il contient.

-Concédant sans autre garantie, expresse ou tacite, que celle prévue à
-l'article 9.2 <#bonne-foi> et notamment sans aucune garantie sur sa
-valeur commerciale, son caractère sécurisé, innovant ou pertinent.
-
-En particulier, le Concédant ne garantit pas que le Logiciel est exempt
-d'erreur, qu'il fonctionnera sans interruption, qu'il sera compatible
-avec l'équipement du Licencié et sa configuration logicielle ni qu'il
-remplira les besoins du Licencié.
-
-9.4 Le Concédant ne garantit pas, de manière expresse ou tacite, que le
-Logiciel ne porte pas atteinte à un quelconque droit de propriété
-intellectuelle d'un tiers portant sur un brevet, un logiciel ou sur tout
-autre droit de propriété. Ainsi, le Concédant exclut toute garantie au
-profit du Licencié contre les actions en contrefaçon qui pourraient être
-diligentées au titre de l'utilisation, de la modification, et de la
-redistribution du Logiciel. Néanmoins, si de telles actions sont
-exercées contre le Licencié, le Concédant lui apportera son expertise
-technique et juridique pour sa défense. Cette expertise technique et
-juridique est déterminée au cas par cas entre le Concédant concerné et
-le Licencié dans le cadre d'un protocole d'accord. Le Concédant dégage
-toute responsabilité quant à l'utilisation de la dénomination du
-Logiciel par le Licencié. Aucune garantie n'est apportée quant à
-l'existence de droits antérieurs sur le nom du Logiciel et sur
-l'existence d'une marque.

-charge par le Contrat, le Concédant pourra résilier de plein droit le
-Contrat trente (30) jours après notification adressée au Licencié et
-restée sans effet.
-
-10.2 Le Licencié dont le Contrat est résilié n'est plus autorisé à
-utiliser, modifier ou distribuer le Logiciel. Cependant, toutes les
-licences qu'il aura concédées antérieurement à la résiliation du Contrat
-resteront valides sous réserve qu'elles aient été effectuées en
-conformité avec le Contrat.

 # Star Monte Carlo
 
-The purpose of this C library is to manage the statistical estimation of a
-function.
+Star-MonteCarlo tries to simplify the calculation of the estimate of a
+user-defined integrator. It ensures the idenpendance of random sequences
+between threads and automates the calculation of expectation, variance
+and standard error.
+
+## Requirements to build
+
+- C compiler
+- POSIX make
+- pkg-config
+- [RSys](https://gitlab.com/vaplv/rsys)
+- [Star-SP](https://gitlab.com/meso-star/star-sp)
 
 ## How to build
 
-The Star-MC library relies on the [CMake](http://www.cmake.org) and the
-[RCMake](https://gitlab.com/vaplv/rcmake/) package to build. It also depends on
-the [RSys](https://gitlab.com/vaplv/rsys/) and the
-[Star-Sampling](https://gitlab.com/meso-star/star-sp/) libraries.
-
-First ensure that CMake is installed on your system. Then install the RCMake
-package as well as the RSys and the Star-Sampling libraries. Finally generate
-the project from the `cmake/CMakeLists.txt` file by appending to the
-`CMAKE_PREFIX_PATH` variable the `<RCMAKE_INSTALL_DIR>`, `<RSYS_INSTALL_DIR>`
-and `<SSP_INSTALL_DIR>` directories, where `<RCMAKE_INSTALL_DIR>`,
-`<RSYS_INSTALL_DIR>` and `<SSP_INSTALL_DIR>` are the install directories of the
-RCMake package, the RSys and the Star-Sampling libraries, respectively. The
-generated project can be edited, built, tested and installed as any CMake
-project.
+Edit config.mk as needed, then run:
+
+    make clean install
 
 ## Release notes
 
+### Version 0.6
+
+- Update `smc_device_create` profile: input arguments are grouped
+  together in the `smc_device_create_args` structure. In addition to the
+  existing input arguments, it contains a new `verbose` member variable
+  which controls the library's verbosity level. By default, the library
+  is silent.
+- Add null constants for the following smc data structures: `smc_type`,
+  `smc_estimator_status`, `smc_integrator` and `smc_doubleN_context`.
+- Replace CMake by Makefile as build system.
+- Update compiler and linker flags to increase the security and
+  robustness of generated binaries.
+- Provide a pkg-config file to link the library as an external
+  dependency.
+
 ### Version 0.5
 
-Sets the required version of Star-SampPling to 0.12.1. The versions 0.12 and
-highers fix compilation errors with gcc 11 but introduces API breaks: the
-`ssp_rng_type` is no longer a structure but becomes an enumeration.

+and highers fix compilation errors with gcc 11 but introduces API
+breaks: the `ssp_rng_type` is no longer a structure but becomes an
+enumeration.
 
 ### Version 0.4.1
 
 - Add a progress log during computations.
-- Sets the CMake minimum version to 3.1: since CMake 3.20, version 2.8 has
-  become obsolete.
+- Sets the CMake minimum version to 3.1: since CMake 3.20, version 2.8
+  has become obsolete.
 
 ### Version 0.4
 
 - Remove the raw integration functionality.
 - Rename the `max_steps` integrator attribute in `max_realisations`.
 - Update the profile of the integrand function of the integrator: the
-  identifier of the thread that invokes the integrand is provided has an input
-  parameter.
-- Add the `smc_device_get_threads_count` function that returns the maximum
-  number of threads used by the device.
+  identifier of the thread that invokes the integrand is provided has an
+  input parameter.
+- Add the `smc_device_get_threads_count` function that returns the
+  maximum number of threads used by the device.
