1 GNU AFFERO GENERAL PUBLIC LICENSE
2 Version 3, 19 November 2007
3
4 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
5 Everyone is permitted to copy and distribute verbatim copies
6 of this license document, but changing it is not allowed.
7
8 Preamble
9
10 The GNU Affero General Public License is a free, copyleft license for
11software and other kinds of works, specifically designed to ensure
12cooperation with the community in the case of network server software.
13
14 The licenses for most software and other practical works are designed
15to take away your freedom to share and change the works. By contrast,
16our General Public Licenses are intended to guarantee your freedom to
17share and change all versions of a program--to make sure it remains free
18software for all its users.
19
20 When we speak of free software, we are referring to freedom, not
21price. Our General Public Licenses are designed to make sure that you
22have the freedom to distribute copies of free software (and charge for
23them if you wish), that you receive source code or can get it if you
24want it, that you can change the software or use pieces of it in new
25free programs, and that you know you can do these things.
26
27 Developers that use our General Public Licenses protect your rights
28with two steps: (1) assert copyright on the software, and (2) offer
29you this License which gives you legal permission to copy, distribute
30and/or modify the software.
31
32 A secondary benefit of defending all users' freedom is that
33improvements made in alternate versions of the program, if they
34receive widespread use, become available for other developers to
35incorporate. Many developers of free software are heartened and
36encouraged by the resulting cooperation. However, in the case of
37software used on network servers, this result may fail to come about.
38The GNU General Public License permits making a modified version and
39letting the public access it on a server without ever releasing its
40source code to the public.
41
42 The GNU Affero General Public License is designed specifically to
43ensure that, in such cases, the modified source code becomes available
44to the community. It requires the operator of a network server to
45provide the source code of the modified version running there to the
46users of that server. Therefore, public use of a modified version, on
47a publicly accessible server, gives the public access to the source
48code of the modified version.
49
50 An older license, called the Affero General Public License and
51published by Affero, was designed to accomplish similar goals. This is
52a different license, not a version of the Affero GPL, but Affero has
53released a new version of the Affero GPL which permits relicensing under
54this license.
55
56 The precise terms and conditions for copying, distribution and
57modification follow.
58
59 TERMS AND CONDITIONS
60
61 0. Definitions.
62
63 "This License" refers to version 3 of the GNU Affero General Public License.
64
65 "Copyright" also means copyright-like laws that apply to other kinds of
66works, such as semiconductor masks.
67
68 "The Program" refers to any copyrightable work licensed under this
69License. Each licensee is addressed as "you". "Licensees" and
70"recipients" may be individuals or organizations.
71
72 To "modify" a work means to copy from or adapt all or part of the work
73in a fashion requiring copyright permission, other than the making of an
74exact copy. The resulting work is called a "modified version" of the
75earlier work or a work "based on" the earlier work.
76
77 A "covered work" means either the unmodified Program or a work based
78on the Program.
79
80 To "propagate" a work means to do anything with it that, without
81permission, would make you directly or secondarily liable for
82infringement under applicable copyright law, except executing it on a
83computer or modifying a private copy. Propagation includes copying,
84distribution (with or without modification), making available to the
85public, and in some countries other activities as well.
86
87 To "convey" a work means any kind of propagation that enables other
88parties to make or receive copies. Mere interaction with a user through
89a computer network, with no transfer of a copy, is not conveying.
90
91 An interactive user interface displays "Appropriate Legal Notices"
92to the extent that it includes a convenient and prominently visible
93feature that (1) displays an appropriate copyright notice, and (2)
94tells the user that there is no warranty for the work (except to the
95extent that warranties are provided), that licensees may convey the
96work under this License, and how to view a copy of this License. If
97the interface presents a list of user commands or options, such as a
98menu, a prominent item in the list meets this criterion.
99
100 1. Source Code.
101
102 The "source code" for a work means the preferred form of the work
103for making modifications to it. "Object code" means any non-source
104form of a work.
105
106 A "Standard Interface" means an interface that either is an official
107standard defined by a recognized standards body, or, in the case of
108interfaces specified for a particular programming language, one that
109is widely used among developers working in that language.
110
111 The "System Libraries" of an executable work include anything, other
112than the work as a whole, that (a) is included in the normal form of
113packaging a Major Component, but which is not part of that Major
114Component, and (b) serves only to enable use of the work with that
115Major Component, or to implement a Standard Interface for which an
116implementation is available to the public in source code form. A
117"Major Component", in this context, means a major essential component
118(kernel, window system, and so on) of the specific operating system
119(if any) on which the executable work runs, or a compiler used to
120produce the work, or an object code interpreter used to run it.
121
122 The "Corresponding Source" for a work in object code form means all
123the source code needed to generate, install, and (for an executable
124work) run the object code and to modify the work, including scripts to
125control those activities. However, it does not include the work's
126System Libraries, or general-purpose tools or generally available free
127programs which are used unmodified in performing those activities but
128which are not part of the work. For example, Corresponding Source
129includes interface definition files associated with source files for
130the work, and the source code for shared libraries and dynamically
131linked subprograms that the work is specifically designed to require,
132such as by intimate data communication or control flow between those
133subprograms and other parts of the work.
134
135 The Corresponding Source need not include anything that users
136can regenerate automatically from other parts of the Corresponding
137Source.
138
139 The Corresponding Source for a work in source code form is that
140same work.
141
142 2. Basic Permissions.
143
144 All rights granted under this License are granted for the term of
145copyright on the Program, and are irrevocable provided the stated
146conditions are met. This License explicitly affirms your unlimited
147permission to run the unmodified Program. The output from running a
148covered work is covered by this License only if the output, given its
149content, constitutes a covered work. This License acknowledges your
150rights of fair use or other equivalent, as provided by copyright law.
151
152 You may make, run and propagate covered works that you do not
153convey, without conditions so long as your license otherwise remains
154in force. You may convey covered works to others for the sole purpose
155of having them make modifications exclusively for you, or provide you
156with facilities for running those works, provided that you comply with
157the terms of this License in conveying all material for which you do
158not control copyright. Those thus making or running the covered works
159for you must do so exclusively on your behalf, under your direction
160and control, on terms that prohibit them from making any copies of
161your copyrighted material outside their relationship with you.
162
163 Conveying under any other circumstances is permitted solely under
164the conditions stated below. Sublicensing is not allowed; section 10
165makes it unnecessary.
166
167 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
168
169 No covered work shall be deemed part of an effective technological
170measure under any applicable law fulfilling obligations under article
17111 of the WIPO copyright treaty adopted on 20 December 1996, or
172similar laws prohibiting or restricting circumvention of such
173measures.
174
175 When you convey a covered work, you waive any legal power to forbid
176circumvention of technological measures to the extent such circumvention
177is effected by exercising rights under this License with respect to
178the covered work, and you disclaim any intention to limit operation or
179modification of the work as a means of enforcing, against the work's
180users, your or third parties' legal rights to forbid circumvention of
181technological measures.
182
183 4. Conveying Verbatim Copies.
184
185 You may convey verbatim copies of the Program's source code as you
186receive it, in any medium, provided that you conspicuously and
187appropriately publish on each copy an appropriate copyright notice;
188keep intact all notices stating that this License and any
189non-permissive terms added in accord with section 7 apply to the code;
190keep intact all notices of the absence of any warranty; and give all
191recipients a copy of this License along with the Program.
192
193 You may charge any price or no price for each copy that you convey,
194and you may offer support or warranty protection for a fee.
195
196 5. Conveying Modified Source Versions.
197
198 You may convey a work based on the Program, or the modifications to
199produce it from the Program, in the form of source code under the
200terms of section 4, provided that you also meet all of these conditions:
201
202 a) The work must carry prominent notices stating that you modified
203 it, and giving a relevant date.
204
205 b) The work must carry prominent notices stating that it is
206 released under this License and any conditions added under section
207 7. This requirement modifies the requirement in section 4 to
208 "keep intact all notices".
209
210 c) You must license the entire work, as a whole, under this
211 License to anyone who comes into possession of a copy. This
212 License will therefore apply, along with any applicable section 7
213 additional terms, to the whole of the work, and all its parts,
214 regardless of how they are packaged. This License gives no
215 permission to license the work in any other way, but it does not
216 invalidate such permission if you have separately received it.
217
218 d) If the work has interactive user interfaces, each must display
219 Appropriate Legal Notices; however, if the Program has interactive
220 interfaces that do not display Appropriate Legal Notices, your
221 work need not make them do so.
222
223 A compilation of a covered work with other separate and independent
224works, which are not by their nature extensions of the covered work,
225and which are not combined with it such as to form a larger program,
226in or on a volume of a storage or distribution medium, is called an
227"aggregate" if the compilation and its resulting copyright are not
228used to limit the access or legal rights of the compilation's users
229beyond what the individual works permit. Inclusion of a covered work
230in an aggregate does not cause this License to apply to the other
231parts of the aggregate.
