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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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.
