+ <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
+
+ <p>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:</p>
+
+ <ul>
+
+ <li>a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.</li>
+
+ <li>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".</li>
+
+ <li>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.</li>
+
+ <li>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.</li>
+
+ </ul>
+
+ <p>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.</p>
+
+ <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
+
+ <p>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:</p>
+
+ <ul>
+
+ <li>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.</li>
+
+ <li>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.</li>
+
+ <li>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.</li>
+
+ <li>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.</li>
+
+ <li>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.</li>
+
+ </ul>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>"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.</p>
+
+ <p>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).</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <h4><a name="section7"></a>7. Additional Terms.</h4>
+
+ <p>"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.</p>
+
+ <p>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.</p>
+
+ <p>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:</p>
+
+ <ul>
+
+ <li>a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or</li>
+
+ <li>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</li>
+
+ <li>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</li>
+
+ <li>d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or</li>
+
+ <li>e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or</li>
+
+ <li>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.</li>
+
+ </ul>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <h4><a name="section8"></a>8. Termination.</h4>
+
+ <p>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).</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
+
+ <p>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.</p>
+
+ <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <h4><a name="section11"></a>11. Patents.</h4>
+
+ <p>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".</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
+
+ <p>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.</p>
+
+ <h4><a name="section13"></a>13. Remote Network Interaction; Use with the GNU General Public License.</h4>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
+
+ <p>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.</p>
+
+ <h4><a name="section16"></a>16. Limitation of Liability.</h4>
+
+ <p>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.</p>
+
+ <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
+
+ <p>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.</p>
+
+ <p>END OF TERMS AND CONDITIONS</p>
+
+ <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+<pre><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

+
+ <p>Also add information on how to contact you by electronic and paper mail.</p>
+
+ <p>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.</p>
+
+ <p>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.

+ that is based on (or derived from) the Work and for which the editorial
+ revisions, annotations, elaborations, or other modifications represent, as
+ a whole, an original work of authorship. For the purposes of this License,
+ Derivative Works shall not include works that remain separable from, or
+ merely link (or bind by name) to the interfaces of, the Work and Derivative
+ Works thereof.</p>
+
+ <p>“Contribution” shall mean any work of authorship, including the original
+ version of the Work and any modifications or additions to that Work or

+ purposes of this definition, “submitted” means any form of electronic,
+ verbal, or written communication sent to the Licensor or its
+ representatives, including but not limited to communication on electronic
+ mailing lists, source code control systems, and issue tracking systems that
+ are managed by, or on behalf of, the Licensor for the purpose of discussing

+
+ <h4>2. Grant of Copyright License.</h4>
+
+ <p>Subject to the terms and conditions of this License, each Contributor hereby
+ grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
+ irrevocable copyright license to reproduce, prepare Derivative Works of, publicly
+ display, publicly perform, sublicense, and distribute the Work and such
+ Derivative Works in Source or Object form.</p>

+
+ <p>Subject to the terms and conditions of this License, each Contributor hereby grants
+ to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+ (except as stated in this section) patent license to make, have made, use,
+ offer to sell, sell, import, and otherwise transfer the Work, where such
+ license applies only to those patent claims licensable by such Contributor
+ that are necessarily infringed by their Contribution(s) alone or by
+ combination of their Contribution(s) with the Work to which such
+ Contribution(s) was submitted. If You institute patent litigation against
+ any entity (including a cross-claim or counterclaim in a lawsuit) alleging
+ that the Work or a Contribution incorporated within the Work constitutes
+ direct or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate as of the
+ date such litigation is filed.</p>
+
+ <h4>4. Redistribution.</h4>
+
+ <p>You may reproduce and distribute copies of the Work or Derivative Works thereof
+ in any medium, with or without modifications, and in Source or Object form, provided
+ that You meet the following conditions:</p>
+
+ <ol>
+ <li>You must give any other recipients of the Work or Derivative Works a
+ copy of this License; and</li>
+
+ <li>You must cause any modified files to carry prominent notices stating
+ that You changed the files; and</li>
