1AFFERO GENERAL PUBLIC LICENSE 2Version 1, March 2002 3 4Copyright © 2002 Affero Inc. 5510 Third Street - Suite 225, San Francisco, CA 94107, USA 6 7This license is a modified version of the GNU General Public License copyright 8(C) 1989, 1991 Free Software Foundation, Inc. made with their permission. 9Section 2(d) has been added to cover use of software over a computer network. 10 11Everyone is permitted to copy and distribute verbatim copies of this license 12document, but changing it is not allowed. 13 14Preamble 15 16The licenses for most software are designed to take away your freedom to share 17and change it. By contrast, the Affero General Public License is intended to 18guarantee your freedom to share and change free software--to make sure the 19software is free for all its users. This Public License applies to most of 20Affero's software and to any other program whose authors commit to using it. 21(Some other Affero software is covered by the GNU Library General Public License 22instead.) You can apply it to your programs, too. 23 24When we speak of free software, we are referring to freedom, not price. This 25General Public License is designed to make sure that you have the freedom to 26distribute copies of free software (and charge for this service if you wish), 27that you receive source code or can get it if you want it, that you can change 28the software or use pieces of it in new free programs; and that you know you can 29do these things. 30 31To protect your rights, we need to make restrictions that forbid anyone to deny 32you these rights or to ask you to surrender the rights. These restrictions 33translate to certain responsibilities for you if you distribute copies of the 34software, or if you modify it. 35 36For example, if you distribute copies of such a program, whether gratis or for a 37fee, you must give the recipients all the rights that you have. You must make 38sure that they, too, receive or can get the source code. And you must show them 39these terms so they know their rights. 40 41We protect your rights with two steps: (1) copyright the software, and (2) offer 42you this license which gives you legal permission to copy, distribute and/or 43modify the software. 44 45Also, for each author's protection and ours, we want to make certain that 46everyone understands that there is no warranty for this free software. If the 47software is modified by someone else and passed on, we want its recipients to 48know that what they have is not the original, so that any problems introduced by 49others will not reflect on the original authors' reputations. 50 51Finally, any free program is threatened constantly by software patents. We wish 52to avoid the danger that redistributors of a free program will individually 53obtain patent licenses, in effect making the program proprietary. To prevent 54this, we have made it clear that any patent must be licensed for everyone's free 55use or not licensed at all. 56 57The precise terms and conditions for copying, distribution and modification 58follow. 59 60TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61 620. This License applies to any program or other work which contains a notice 63 placed by the copyright holder saying it may be distributed under the terms 64 of this Affero General Public License. The "Program", below, refers to any 65 such program or work, and a "work based on the Program" means either the 66 Program or any derivative work under copyright law: that is to say, a work 67 containing the Program or a portion of it, either verbatim or with 68 modifications and/or translated into another language. (Hereinafter, 69 translation is included without limitation in the term "modification".) Each 70 licensee is addressed as "you". 71 72 Activities other than copying, distribution and modification are not covered 73 by this License; they are outside its scope. The act of running the Program 74 is not restricted, and the output from the Program is covered only if its 75 contents constitute a work based on the Program (independent of having been 76 made by running the Program). Whether that is true depends on what the 77 Program does. 78 791. You may copy and distribute verbatim copies of the Program's source code as 80 you receive it, in any medium, provided that you conspicuously and 81 appropriately publish on each copy an appropriate copyright notice and 82 disclaimer of warranty; keep intact all the notices that refer to this 83 License and to the absence of any warranty; and give any other recipients of 84 the Program a copy of this License along with the Program. 85 86 You may charge a fee for the physical act of transferring a copy, and you may 87 at your option offer warranty protection in exchange for a fee. 88 892. You may modify your copy or copies of the Program or any portion of it, thus 90 forming a work based on the Program, and copy and distribute such 91 modifications or work under the terms of Section 1 above, provided that you 92 also meet all of these conditions: 93 94 a) You must cause the modified files to carry prominent notices stating 95 that you changed the files and the date of any change. 96 97 b) You must cause any work that you distribute or publish, that in whole or 98 in part contains or is derived from the Program or any part thereof, to be 99 licensed as a whole at no charge to all third parties under the terms of 100 this License. 101 102 c) If the modified program normally reads commands interactively when run, you 103 must cause it, when started running for such interactive use in the most 104 ordinary way, to print or display an announcement including an appropriate 105 copyright notice and a notice that there is no warranty (or else, saying 106 that you provide a warranty) and that users may redistribute the program 107 under these conditions, and telling the user how to view a copy of this 108 License. (Exception: if the Program itself is interactive but does not 109 normally print such an announcement, your work based on the Program is not 110 required to print an announcement.) 111 112 d) If the Program as you received it is intended to interact with users 113 through a computer network and if, in the version you received, any user 114 interacting with the Program was given the opportunity to request 115 transmission to that user of the Program's complete source code, you must 116 not remove that facility from your modified version of the Program or work 117 based on the Program, and must offer an equivalent opportunity for all 118 users interacting with your Program through a computer network to request 119 immediate transmission by HTTP of the complete source code of your 120 modified version or other derivative work. 121 122 These requirements apply to the modified work as a whole. If identifiable 123 sections of that work are not derived from the Program, and can be reasonably 124 considered independent and separate works in themselves, then this License, 125 and its terms, do not apply to those sections when you distribute them as 126 separate works. But when you distribute the same sections as part of a whole 127 which is a work based on the Program, the distribution of the whole must be 128 on the terms of this License, whose permissions for other licensees extend to 129 the entire whole, and thus to each and every part regardless of who wrote it. 130 131 Thus, it is not the intent of this section to claim rights or contest your 132 rights to work written entirely by you; rather, the intent is to exercise the 133 right to control the distribution of derivative or collective works based on 134 the Program. 135 136 In addition, mere aggregation of another work not based on the Program with 137 the Program (or with a work based on the Program) on a volume of a storage or 138 distribution medium does not bring the other work under the scope of this 139 License. 140 1413. You may copy and distribute the Program (or a work based on it, under Section 142 2) in object code or executable form under the terms of Sections 1 and 2 143 above provided that you also do one of the following: 144 145 a) Accompany it with the complete corresponding machine-readable source code, 146 which must be distributed under the terms of Sections 1 and 2 above on a 147 medium customarily used for software interchange; or, 148 149 b) Accompany it with a written offer, valid for at least three years, to give 150 any third party, for a charge no more than your cost of physically 151 performing source distribution, a complete machine-readable copy of the 152 corresponding source code, to be distributed under the terms of Sections 1 153 and 2 above on a medium customarily used for software interchange; or, 154 155 c) Accompany it with the information you received as to the offer to 156 distribute corresponding source code. (This alternative is allowed only 157 for noncommercial distribution and only if you received the program in 158 object code or executable form with such an offer, in accord with 159 Subsection b above.) 160 161 The source code for a work means the preferred form of the work for making 162 modifications to it. For an executable work, complete source code means all 163 the source code for all modules it contains, plus any associated interface 164 definition files, plus the scripts used to control compilation and 165 installation of the executable. However, as a special exception, the source 166 code distributed need not include anything that is normally distributed (in 167 either source or binary form) with the major components (compiler, kernel, 168 and so on) of the operating system on which the executable runs, unless that 169 component itself accompanies the executable. 170 171 If distribution of executable or object code is made by offering access to 172 copy from a designated place, then offering equivalent access to copy the 173 source code from the same place counts as distribution of the source code, 174 even though third parties are not compelled to copy the source along with the 175 object code. 176 1774. You may not copy, modify, sublicense, or distribute the Program except as 178 expressly provided under this License. Any attempt otherwise to copy, modify, 179 sublicense or distribute the Program is void, and will automatically 180 terminate your rights under this License. However, parties who have received 181 copies, or rights, from you under this License will not have their licenses 182 terminated so long as such parties remain in full compliance. 183 1845. You are not required to accept this License, since you have not signed it. 185 However, nothing else grants you permission to modify or distribute the 186 Program or its derivative works. These actions are prohibited by law if you 187 do not accept this License. Therefore, by modifying or distributing the 188 Program (or any work based on the Program), you indicate your acceptance of 189 this License to do so, and all its terms and conditions for copying, 190 distributing or modifying the Program or works based on it. 191 1926. Each time you redistribute the Program (or any work based on the Program), 193 the recipient automatically receives a license from the original licensor to 194 copy, distribute or modify the Program subject to these terms and conditions. 195 You may not impose any further restrictions on the recipients' exercise of 196 the rights granted herein. You are not responsible for enforcing compliance 197 by third parties to this License. 198 1997. If, as a consequence of a court judgment or allegation of patent infringement 200 or for any other reason (not limited to patent issues), conditions are 201 imposed on you (whether by court order, agreement or otherwise) that 202 contradict the conditions of this License, they do not excuse you from the 203 conditions of this License. If you cannot distribute so as to satisfy 204 simultaneously your obligations under this License and any other pertinent 205 obligations, then as a consequence you may not distribute the Program at all. 206 For example, if a patent license would not permit royalty-free redistribution 207 of the Program by all those who receive copies directly or indirectly through 208 you, then the only way you could satisfy both it and this License would be to 209 refrain entirely from distribution of the Program. 210 211 If any portion of this section is held invalid or unenforceable under any 212 particular circumstance, the balance of the section is intended to apply and 213 the section as a whole is intended to apply in other circumstances. 214 215 It is not the purpose of this section to induce you to infringe any patents 216 or other property right claims or to contest validity of any such claims; 217 this section has the sole purpose of protecting the integrity of the free 218 software distribution system, which is implemented by public license 219 practices. Many people have made generous contributions to the wide range of 220 software distributed through that system in reliance on consistent 221 application of that system; it is up to the author/donor to decide if he or 222 she is willing to distribute software through any other system and a licensee 223 cannot impose that choice. 224 225 This section is intended to make thoroughly clear what is believed to be a 226 consequence of the rest of this License. 227 2288. If the distribution and/or use of the Program is restricted in certain 229 countries either by patents or by copyrighted interfaces, the original 230 copyright holder who places the Program under this License may add an 231 explicit geographical distribution limitation excluding those countries, so 232 that distribution is permitted only in or among countries not thus excluded. 233 In such case, this License incorporates the limitation as if written in the 234 body of this License. 235 2369. Affero Inc. may publish revised and/or new versions of the Affero General 237 Public License from time to time. Such new versions will be similar in spirit 238 to the present version, but may differ in detail to address new problems or 239 concerns. 240 241 Each version is given a distinguishing version number. If the Program 242 specifies a version number of this License which applies to it and "any later 243 version", you have the option of following the terms and conditions either of 244 that version or of any later version published by Affero, Inc. If the Program 245 does not specify a version number of this License, you may choose any version 246 ever published by Affero, Inc. 247 248 You may also choose to redistribute modified versions of this program under 249 any version of the Free Software Foundation's GNU General Public License 250 version 3 or higher, so long as that version of the GNU GPL includes terms 251 and conditions substantially equivalent to those of this license. 252 25310. If you wish to incorporate parts of the Program into other free programs 254 whose distribution conditions are different, write to the author to ask for 255 permission. For software which is copyrighted by Affero, Inc., write to us; 256 we sometimes make exceptions for this. Our decision will be guided by the 257 two goals of preserving the free status of all derivatives of our free 258 software and of promoting the sharing and reuse of software generally. 259 260NO WARRANTY 261 26211. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE 263 PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE 264 STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE 265 PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, 266 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND 267 FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND 268 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, 269 YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 270 27112. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL 272 ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 273 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 274 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE 275 OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA 276 OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 277 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 278 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 279 SUCH DAMAGES. 280
