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.
