- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
- 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.
- 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
