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 GNU 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 General Public License +applies to most of the Free Software Foundation's software and to any other +program whose authors commit to using it. (Some other Free Software +Foundation 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. Our +General Public Licenses are 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. + + GNU GENERAL PUBLIC LICENSE + 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 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.) + +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. The Free Software Foundation may publish revised and/or new versions +of the 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 the Free Software Foundation. If +the Program does not specify a version number of this License, you may +choose any version ever published by the Free Software Foundation. + +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 the Free Software +Foundation, write to the Free Software Foundation; 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. + + END OF TERMS AND CONDITIONS --- README.txt +++ README.txt @@ -0,0 +1,41 @@ +$Id$ + +----------------------- + OVERVIEW +----------------------- +The Views Tagadelic module allows users to create a tag cloud as the output from a view.
