| |
| This license is a modified version of the GNU General Public License copyright |
| (C) 1989, 1991 Free Software Foundation, Inc. made with their permission. |
| Section 2(d) has been added to cover use of software over a computer network. |
| |
| Everyone is permitted to copy and distribute verbatim copies of this license |
| document, but changing it is not allowed. |
| |
| Preamble |
| |
| The licenses for most software are designed to take away your freedom to share |
| and change it. By contrast, the Affero General Public License is intended to |
| guarantee your freedom to share and change free software--to make sure the |
| software is free for all its users. This Public License applies to most of |
| Affero's software and to any other program whose authors commit to using it. |
| (Some other Affero software is covered by the GNU Library General Public License |
| instead.) You can apply it to your programs, too. |
| |
| When we speak of free software, we are referring to freedom, not price. This |
| General Public License is designed to make sure that you have the freedom to |
| distribute copies of free software (and charge for this service 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. |
| |
| To protect your rights, we need to make restrictions that forbid anyone to deny |
| you these rights or to ask you to surrender the rights. These restrictions |
| translate to certain responsibilities for you if you distribute copies of the |
| software, or if you modify it. |
| |
| For example, if you distribute copies of such a program, whether gratis or for a |
| fee, you must give the recipients all the rights that you have. You must make |
| sure that they, too, receive or can get the source code. And you must show them |
| these terms so they know their rights. |
| |
| We protect your rights with two steps: (1) copyright the software, and (2) offer |
| you this license which gives you legal permission to copy, distribute and/or |
| modify the software. |
| |
| Also, for each author's protection and ours, we want to make certain that |
| everyone understands that there is no warranty for this free software. If the |
| software is modified by someone else and passed on, we want its recipients to |
| know that what they have is not the original, so that any problems introduced by |
| others will not reflect on the original authors' reputations. |
| |
| Finally, any free program is threatened constantly by software patents. We wish |
| to avoid the danger that redistributors of a free program will individually |
| obtain patent licenses, in effect making the program proprietary. To prevent |
| this, we have made it clear that any patent must be licensed for everyone's free |
| use or not licensed at all. |
| |
| The precise terms and conditions for copying, distribution and modification |
| follow. |
| |
| TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
| |
| 0. This License applies to any program or other work which contains a notice |
| placed by the copyright holder saying it may be distributed under the terms |
| of this Affero General Public License. The "Program", below, refers to any |
| such program or work, and a "work based on the Program" means either the |
| Program or any derivative work under copyright law: that is to say, a work |
| containing the Program or a portion of it, either verbatim or with |
| modifications and/or translated into another language. (Hereinafter, |
| translation is included without limitation in the term "modification".) Each |
| licensee is addressed as "you". |
| |
| Activities other than copying, distribution and modification are not covered |
| by this License; they are outside its scope. The act of running the Program |
| is not restricted, and the output from the Program is covered only if its |
| contents constitute a work based on the Program (independent of having been |
| made by running the Program). Whether that is true depends on what the |
| Program does. |
| |
| 1. You may copy and distribute 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 and |
| disclaimer of warranty; keep intact all the notices that refer to this |
| License and to the absence of any warranty; and give any other recipients of |
| the Program a copy of this License along with the Program. |
| |
| You may charge a fee for the physical act of transferring a copy, and you may |
| at your option offer warranty protection in exchange for a fee. |
| |
| 2. You may modify your copy or copies of the Program or any portion of it, thus |
| forming a work based on the Program, and copy and distribute such |
| modifications or work under the terms of Section 1 above, provided that you |
| also meet all of these conditions: |
| |
| a) You must cause the modified files to carry prominent notices stating |
| that you changed the files and the date of any change. |
| |
| b) You must cause any work that you distribute or publish, that in whole or |
| in part contains or is derived from the Program or any part thereof, to be |
| licensed as a whole at no charge to all third parties under the terms of |
| this License. |
| |
| c) If the modified program normally reads commands interactively when run, you |
| must cause it, when started running for such interactive use in the most |
| ordinary way, to print or display an announcement including an appropriate |
| copyright notice and a notice that there is no warranty (or else, saying |
| that you provide a warranty) and that users may redistribute the program |
| under these conditions, and telling the user how to view a copy of this |
| License. (Exception: if the Program itself is interactive but does not |
| normally print such an announcement, your work based on the Program is not |
| required to print an announcement.) |
| |
| d) If the Program as you received it is intended to interact with users |
| through a computer network and if, in the version you received, any user |
| interacting with the Program was given the opportunity to request |
| transmission to that user of the Program's complete source code, you must |
| not remove that facility from your modified version of the Program or work |
| based on the Program, and must offer an equivalent opportunity for all |
| users interacting with your Program through a computer network to request |
| immediate transmission by HTTP of the complete source code of your |
| modified version or other derivative work. |
| |
| These requirements apply to the modified work as a whole. If identifiable |
| sections of that work are not derived from the Program, and can be reasonably |
| considered independent and separate works in themselves, then this License, |
| and its terms, do not apply to those sections when you distribute them as |
| separate works. But when you distribute the same sections as part of a whole |
| which is a work based on the Program, the distribution of the whole must be |
| on the terms of this License, whose permissions for other licensees extend to |
| the entire whole, and thus to each and every part regardless of who wrote it. |
| |
| Thus, it is not the intent of this section to claim rights or contest your |
| rights to work written entirely by you; rather, the intent is to exercise the |
| right to control the distribution of derivative or collective works based on |
| the Program. |
| |
| In addition, mere aggregation of another work not based on the Program with |
| the Program (or with a work based on the Program) on a volume of a storage or |
| distribution medium does not bring the other work under the scope of this |
| License. |
| |
| 3. You may copy and distribute the Program (or a work based on it, under Section |
| 2) in object code or executable form under the terms of Sections 1 and 2 |
| above provided that you also do one of the following: |
| |
| a) Accompany it with the complete corresponding machine-readable source code, |
| which must be distributed under the terms of Sections 1 and 2 above on a |
| medium customarily used for software interchange; or, |
| |
| b) Accompany it with a written offer, valid for at least three years, to give |
| any third party, for a charge no more than your cost of physically |
| performing source distribution, a complete machine-readable copy of the |
| corresponding source code, to be distributed under the terms of Sections 1 |
| and 2 above on a medium customarily used for software interchange; or, |
| |
| c) Accompany it with the information you received as to the offer to |
| distribute corresponding source code. (This alternative is allowed only |
| for noncommercial distribution and only if you received the program in |
| object code or executable form with such an offer, in accord with |
| Subsection b above.) |
| |
| The source code for a work means the preferred form of the work for making |
| modifications to it. For an executable work, complete source code means all |
| the source code for all modules it contains, plus any associated interface |
| definition files, plus the scripts used to control compilation and |
| installation of the executable. However, as a special exception, the source |
| code distributed need not include anything that is normally distributed (in |
| either source or binary form) with the major components (compiler, kernel, |
| and so on) of the operating system on which the executable runs, unless that |
| component itself accompanies the executable. |
| |
| If distribution of executable or object code is made by offering access to |
| copy from a designated place, then offering equivalent access to copy the |
| source code from the same place counts as distribution of the source code, |
| even though third parties are not compelled to copy the source along with the |
| object code. |
| |
| 4. You may not copy, modify, sublicense, or distribute the Program except as |
| expressly provided under this License. Any attempt otherwise to copy, modify, |
| sublicense or distribute the Program is void, and will automatically |
| terminate your rights under this License. However, parties who have received |
| copies, or rights, from you under this License will not have their licenses |
| terminated so long as such parties remain in full compliance. |
| |
| 5. You are not required to accept this License, since you have not signed it. |
| However, nothing else grants you permission to modify or distribute the |
| Program or its derivative works. These actions are prohibited by law if you |
| do not accept this License. Therefore, by modifying or distributing the |
| Program (or any work based on the Program), you indicate your acceptance of |
| this License to do so, and all its terms and conditions for copying, |
| distributing or modifying the Program or works based on it. |
| |
| 6. Each time you redistribute the Program (or any work based on the Program), |
| the recipient automatically receives a license from the original licensor to |
| copy, distribute or modify the Program subject to these terms and conditions. |
| You may not impose any further restrictions on the recipients' exercise of |
| the rights granted herein. You are not responsible for enforcing compliance |
| by third parties to this License. |
| |
| 7. If, as a consequence of a court judgment or allegation of patent infringement |
| or for any other reason (not limited to patent issues), 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 distribute so as to satisfy |
| simultaneously your obligations under this License and any other pertinent |
| obligations, then as a consequence you may not distribute the Program at all. |
| For example, if a patent license would not permit royalty-free redistribution |
| of the Program by all those who receive copies directly or indirectly through |
| you, then the only way you could satisfy both it and this License would be to |
| refrain entirely from distribution of the Program. |
| |
| If any portion of this section is held invalid or unenforceable under any |
| particular circumstance, the balance of the section is intended to apply and |
| the section as a whole is intended to apply in other circumstances. |
| |
| It is not the purpose of this section to induce you to infringe any patents |
| or other property right claims or to contest validity of any such claims; |
| this section has the sole purpose of protecting the integrity of the free |
| software distribution system, which is implemented by public license |
| practices. Many people have made generous contributions to the wide range of |
| software distributed through that system in reliance on consistent |
| application of that system; it is up to the author/donor to decide if he or |
| she is willing to distribute software through any other system and a licensee |
| cannot impose that choice. |
| |
| This section is intended to make thoroughly clear what is believed to be a |
| consequence of the rest of this License. |
| |
| 8. If the distribution and/or use of the Program is restricted in certain |
| countries either by patents or by copyrighted interfaces, the original |
| copyright holder who places the Program under this License may add an |
| explicit geographical distribution limitation excluding those countries, so |
| that distribution is permitted only in or among countries not thus excluded. |
| In such case, this License incorporates the limitation as if written in the |
| body of this License. |
| |
| 9. Affero Inc. may publish revised and/or new versions of the 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 a version number of this License which applies to it and "any later |
| version", you have the option of following the terms and conditions either of |
| that version or of any later version published by Affero, Inc. If the Program |
| does not specify a version number of this License, you may choose any version |
| ever published by Affero, Inc. |
| |
| You may also choose to redistribute modified versions of this program under |
| any version of the Free Software Foundation's GNU General Public License |
| version 3 or higher, so long as that version of the GNU GPL includes terms |
| and conditions substantially equivalent to those of this license. |
| |
| 10. If you wish to incorporate parts of the Program into other free programs |
| whose distribution conditions are different, write to the author to ask for |
| permission. For software which is copyrighted by Affero, Inc., write to us; |
| we sometimes make exceptions for this. Our decision will be guided by the |
| two goals of preserving the free status of all derivatives of our free |
| software and of promoting the sharing and reuse of software generally. |
| |
| NO WARRANTY |
| |
| 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. |
| |
| 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL |
| ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE |
| 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. |
