+GNU AFFERO GENERAL PUBLIC LICENSE
+Version 3, 19 November 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 Affero General Public License is a free, copyleft license for software
+and other kinds of works, specifically designed to ensure cooperation with
+the community in the case of network server software.
+
+The licenses for most software and other practical works are designed to take
+away your freedom to share and change the works.  By contrast, our General
+Public Licenses are 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.
+
+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.
+
+Developers that use our General Public Licenses protect your rights with two
+steps: (1) assert copyright on the software, and (2) offer you this License
+which gives you legal permission to copy, distribute and/or modify the software.
+
+A secondary benefit of defending all users' freedom is that improvements made
+in alternate versions of the program, if they receive widespread use, become
+available for other developers to incorporate.  Many developers of free software
+are heartened and encouraged by the resulting cooperation.  However, in the
+case of software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and letting
+the public access it on a server without ever releasing its source code to
+the public.
+
+The GNU Affero General Public License is designed specifically to ensure that,
+in such cases, the modified source code becomes available to the community.
+It requires the operator of a network server to provide the source code of
+the modified version running there to the users of that server.  Therefore,
+public use of a modified version, on a publicly accessible server, gives the
+public access to the source code of the modified version.
+
+An older license, called the Affero General Public License and published by
+Affero, was designed to accomplish similar goals.  This is a different license,
+not a version of the Affero GPL, but Affero has released a new version of
+the Affero GPL which permits relicensing under this license.
+
+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 Affero 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. Remote Network Interaction; Use with the GNU General Public License.
+
+Notwithstanding any other provision of this License, if you modify the Program,
+your modified version must prominently offer all users interacting with it
+remotely through a computer network (if your version supports such interaction)
+an opportunity to receive the Corresponding Source of your version by providing
+access to the Corresponding Source from a network server at no charge, through
+some standard or customary means of facilitating copying of software.  This
+Corresponding Source shall include the Corresponding Source for any work covered
+by version 3 of the GNU General Public License that is incorporated pursuant
+to the following paragraph.
+
+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 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 work with which it is combined will remain
+governed by version 3 of the GNU General Public License.
+
+14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions of the
+GNU Affero 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 Affero 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 Affero 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 Affero 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 Affero 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 Affero General Public License for more
+details.
+
+You should have received a copy of the GNU Affero 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 your software can interact with users remotely through a computer network,
+you should also make sure that it provides a way for users to get its source.
+For example, if your program is a web application, its interface could display
+a "Source" link that leads users to an archive of the code.  There are many
+ways you could offer source, and different solutions will be better for different
+programs; see section 13 for the specific requirements.
+
+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 AGPL, see <http://www.gnu.org/licenses/>.

+Licence Art Libre 1.3 (LAL 1.3)
+
+Préambule :
+
+Avec la Licence Art Libre, l’autorisation est donnée de copier, de diffuser
+et de transformer librement les œuvres dans le respect des droits de l’auteur.
+
+Loin d’ignorer ces droits, la Licence Art Libre les reconnaît et les protège.
+Elle en reformule l’exercice en permettant à tout un chacun de faire un usage
+créatif des productions de l’esprit quels que soient leur genre et leur forme
+d’expression.
+
+Si, en règle générale, l’application du droit d’auteur conduit à restreindre
+l’accès aux œuvres de l’esprit, la Licence Art Libre, au contraire, le favorise.
+L’intention est d’autoriser l’utilisation des ressources d’une œuvre ; créer
+de nouvelles conditions de création pour amplifier les possibilités de création.
+La Licence Art Libre permet d’avoir jouissance des œuvres tout en reconnaissant
+les droits et les responsabilités de chacun.
+
+Avec le développement du numérique, l’invention d’internet et des logiciels
+libres, les modalités de création ont évolué : les productions de l’esprit
+s’offrent naturellement à la circulation, à l’échange et aux transformations.
+Elles se prêtent favorablement à la réalisation d’œuvres communes que chacun
+peut augmenter pour l’avantage de tous.
+
+C’est la raison essentielle de la Licence Art Libre : promouvoir et protéger
+ces productions de l’esprit selon les principes du copyleft : liberté d’usage,
+de copie, de diffusion, de transformation et interdiction d’appropriation
+exclusive.
+
+Définitions :
+
+Nous désignons par « œuvre », autant l’œuvre initiale, les œuvres conséquentes,
+que l’œuvre commune telles que définies ci-après :
+
+L’œuvre commune :Il s’agit d’une œuvre qui comprend l’œuvre initiale ainsi
+que toutes les contributions postérieures (les originaux conséquents et les
+copies). Elle est créée à l’initiative de l’auteur initial qui par cette licence
+définit les conditions selon lesquelles les contributions sont faites.
+
+L’œuvre initiale :C’est-à-dire l’œuvre créée par l’initiateur de l’œuvre commune
+dont les copies vont être modifiées par qui le souhaite.
+
+Les œuvres conséquentes :C’est-à-dire les contributions des auteurs qui participent
+à la formation de l’œuvre commune en faisant usage des droits de reproduction,
+de diffusion et de modification que leur confère la licence.
+
+Originaux (sources ou ressources de l’œuvre) :Chaque exemplaire daté de l’œuvre
+initiale ou conséquente que leurs auteurs présentent comme référence pour
+toutes actualisations, interprétations, copies ou reproductions ultérieures.
+
+Copie :Toute reproduction d’un original au sens de cette licence.
+
+1- OBJET.
+Cette licence a pour objet de définir les conditions selon lesquelles vous
+pouvez jouir librement de l’œuvre.
+
+2. L’ÉTENDUE DE LA JOUISSANCE.
+Cette œuvre est soumise au droit d’auteur, et l’auteur par cette licence vous
+indique quelles sont vos libertés pour la copier, la diffuser et la modifier.
+
+2.1 LA LIBERTÉ DE COPIER (OU DE REPRODUCTION).
+Vous avez la liberté de copier cette œuvre pour vous, vos amis ou toute autre
+personne, quelle que soit la technique employée.
+
+2.2 LA LIBERTÉ DE DIFFUSER (INTERPRÉTER, REPRÉSENTER, DISTRIBUER).
+Vous pouvez diffuser librement les copies de ces œuvres, modifiées ou non,
+quel que soit le support, quel que soit le lieu, à titre onéreux ou gratuit,
+si vous respectez toutes les conditions suivantes :
+
+1.	joindre aux copies cette licence à l’identique ou indiquer précisément
+où se trouve la licence ;
+2.	indiquer au destinataire le nom de chaque auteur des originaux, y compris
+le vôtre si vous avez modifié l’œuvre ;
+3.	indiquer au destinataire où il pourrait avoir accès aux originaux (initiaux
+et/ou conséquents).
+
+Les auteurs des originaux pourront, s’ils le souhaitent, vous autoriser à
+diffuser l’original dans les mêmes conditions que les copies.
+
+2.3 LA LIBERTÉ DE MODIFIER.
+Vous avez la liberté de modifier les copies des originaux (initiaux et conséquents)
+dans le respect des conditions suivantes :
+
+1.	celles prévues à l’article 2.2 en cas de diffusion de la copie modifiée
+;
+2.	indiquer qu’il s’agit d’une œuvre modifiée et, si possible, la nature de
+la modification ;
+3.	diffuser cette œuvre conséquente avec la même licence ou avec toute licence
+compatible ;
+4.	Les auteurs des originaux pourront, s’ils le souhaitent, vous autoriser
+à modifier l’original dans les mêmes conditions que les copies.
+
+3. DROITS CONNEXES.
+Les actes donnant lieu à des droits d’auteur ou des droits voisins ne doivent
+pas constituer un obstacle aux libertés conférées par cette licence. C’est
+pourquoi, par exemple, les interprétations doivent être soumises à la même
+licence ou une licence compatible. De même, l’intégration de l’œuvre à une
+base de données, une compilation ou une anthologie ne doit pas faire obstacle
+à la jouissance de l’œuvre telle que définie par cette licence.
+
+4. L’ INTÉGRATION DE L’ŒUVRE.
+Toute intégration de cette œuvre à un ensemble non soumis à la LAL doit assurer
+l’exercice des libertés conférées par cette licence.
+Si l’œuvre n’est plus accessible indépendamment de l’ensemble, alors l’intégration
+n’est possible qu’à condition que l’ensemble soit soumis à la LAL ou une licence
+compatible.
+
+5. CRITÈRES DE COMPATIBILITÉ.
+Une licence est compatible avec la LAL si et seulement si :
+
+1.	elle accorde l’autorisation de copier, diffuser et modifier des copies
+de l’œuvre, y compris à des fins lucratives, et sans autres restrictions que
+celles qu’impose le respect des autres critères de compatibilité ;
+2.	elle garantit la paternité de l’œuvre et l’accès aux versions antérieures
+de l’œuvre quand cet accès est possible ;
+     3.	elle reconnaît la LAL également compatible (réciprocité) ;
+4.	elle impose que les modifications faites sur l’œuvre soient soumises à
+la même licence ou encore à une licence répondant aux critères de compatibilité
+posés par la LAL.
+
+6. VOS DROITS INTELLECTUELS.
+La LAL n’a pas pour objet de nier vos droits d’auteur sur votre contribution
+ni vos droits connexes. En choisissant de contribuer à l’évolution de cette
+œuvre commune, vous acceptez seulement d’offrir aux autres les mêmes autorisations
+sur votre contribution que celles qui vous ont été accordées par cette licence.
+Ces autorisations n’entraînent pas un dessaisissement de vos droits intellectuels.
+
+7. VOS RESPONSABILITÉS.
+La liberté de jouir de l’œuvre tel que permis par la LAL (liberté de copier,
+diffuser, modifier) implique pour chacun la responsabilité de ses propres
+faits.
+
+8. LA DURÉE DE LA LICENCE.
+Cette licence prend effet dès votre acceptation de ses dispositions. Le fait
+de copier, de diffuser, ou de modifier l’œuvre constitue une acceptation tacite.
+Cette licence a pour durée la durée des droits d’auteur attachés à l’œuvre.
+Si vous ne respectez pas les termes de cette licence, vous perdez automatiquement
+les droits qu’elle vous confère. Si le régime juridique auquel vous êtes soumis
+ne vous permet pas de respecter les termes de cette licence, vous ne pouvez
+pas vous prévaloir des libertés qu’elle confère.
+
+9. LES DIFFÉRENTES VERSIONS DE LA LICENCE.
+Cette licence pourra être modifiée régulièrement, en vue de son amélioration,
+par ses auteurs (les acteurs du mouvement Copyleft Attitude) sous la forme
+de nouvelles versions numérotées.
+Vous avez toujours le choix entre vous contenter des dispositions contenues
+dans la version de la LAL sous laquelle la copie vous a été communiquée ou
+alors, vous prévaloir des dispositions d’une des versions ultérieures.
+
+10. LES SOUS-LICENCES.
+Les sous-licences ne sont pas autorisées par la présente. Toute personne qui
+souhaite bénéficier des libertés qu’elle confère sera liée directement aux
+auteurs de l’œuvre commune.
+
+11. LE CONTEXTE JURIDIQUE.
+Cette licence est rédigée en référence au droit français et à la Convention
+de Berne relative au droit d’auteur.
