 | 
						
						
						
							|  |                        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
 |

							|  |             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

 |

							|  |     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

							|  | 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.
