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 -+ -+ 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 -+convey 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 General Public License as published by -+ the Free Software Foundation; either version 2 of the License, or -+ (at your option) any later version. -+ -+ 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 -+ GNU General Public License for more details. -+ -+ You should have received a copy of the GNU General Public License -+ along with this program; if not, write to the Free Software -+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA -+ -+ -+Also add information on how to contact you by electronic and paper mail. -+ -+If the program is interactive, make it output a short notice like this -+when it starts in an interactive mode: -+ -+ Gnomovision version 69, Copyright (C) year name of author -+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. -+ This is free software, and you are welcome to redistribute it -+ under certain conditions; type `show c' for details. -+ -+The hypothetical commands `show w' and `show c' should show the appropriate -+parts of the General Public License. Of course, the commands you use may -+be called something other than `show w' and `show c'; they could even be -+mouse-clicks or menu items--whatever suits your program. -+ -+You should also get your employer (if you work as a programmer) or your -+school, if any, to sign a "copyright disclaimer" for the program, if -+necessary. Here is a sample; alter the names: -+ -+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program -+ `Gnomovision' (which makes passes at compilers) written by James Hacker. -+ -+ <signature of Ty Coon>, 1 April 1989 -+ Ty Coon, President of Vice -+ -+This General Public License does not permit incorporating your program into -+proprietary programs.
