darkhan@105: GNU GENERAL PUBLIC LICENSE
darkhan@105: Version 2, June 1991
darkhan@105:
darkhan@105: Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
darkhan@105: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
darkhan@105: Everyone is permitted to copy and distribute verbatim copies
darkhan@105: of this license document, but changing it is not allowed.
darkhan@105:
darkhan@105: Preamble
darkhan@105:
darkhan@105: The licenses for most software are designed to take away your
darkhan@105: freedom to share and change it. By contrast, the GNU General Public
darkhan@105: License is intended to guarantee your freedom to share and change free
darkhan@105: software--to make sure the software is free for all its users. This
darkhan@105: General Public License applies to most of the Free Software
darkhan@105: Foundation's software and to any other program whose authors commit to
darkhan@105: using it. (Some other Free Software Foundation software is covered by
darkhan@105: the GNU Lesser General Public License instead.) You can apply it to
darkhan@105: your programs, too.
darkhan@105:
darkhan@105: When we speak of free software, we are referring to freedom, not
darkhan@105: price. Our General Public Licenses are designed to make sure that you
darkhan@105: have the freedom to distribute copies of free software (and charge for
darkhan@105: this service if you wish), that you receive source code or can get it
darkhan@105: if you want it, that you can change the software or use pieces of it
darkhan@105: in new free programs; and that you know you can do these things.
darkhan@105:
darkhan@105: To protect your rights, we need to make restrictions that forbid
darkhan@105: anyone to deny you these rights or to ask you to surrender the rights.
darkhan@105: These restrictions translate to certain responsibilities for you if you
darkhan@105: distribute copies of the software, or if you modify it.
darkhan@105:
darkhan@105: For example, if you distribute copies of such a program, whether
darkhan@105: gratis or for a fee, you must give the recipients all the rights that
darkhan@105: you have. You must make sure that they, too, receive or can get the
darkhan@105: source code. And you must show them these terms so they know their
darkhan@105: rights.
darkhan@105:
darkhan@105: We protect your rights with two steps: (1) copyright the software, and
darkhan@105: (2) offer you this license which gives you legal permission to copy,
darkhan@105: distribute and/or modify the software.
darkhan@105:
darkhan@105: Also, for each author's protection and ours, we want to make certain
darkhan@105: that everyone understands that there is no warranty for this free
darkhan@105: software. If the software is modified by someone else and passed on, we
darkhan@105: want its recipients to know that what they have is not the original, so
darkhan@105: that any problems introduced by others will not reflect on the original
darkhan@105: authors' reputations.
darkhan@105:
darkhan@105: Finally, any free program is threatened constantly by software
darkhan@105: patents. We wish to avoid the danger that redistributors of a free
darkhan@105: program will individually obtain patent licenses, in effect making the
darkhan@105: program proprietary. To prevent this, we have made it clear that any
darkhan@105: patent must be licensed for everyone's free use or not licensed at all.
darkhan@105:
darkhan@105: The precise terms and conditions for copying, distribution and
darkhan@105: modification follow.
darkhan@105:
darkhan@105: GNU GENERAL PUBLIC LICENSE
darkhan@105: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
darkhan@105:
darkhan@105: 0. This License applies to any program or other work which contains
darkhan@105: a notice placed by the copyright holder saying it may be distributed
darkhan@105: under the terms of this General Public License. The "Program", below,
darkhan@105: refers to any such program or work, and a "work based on the Program"
darkhan@105: means either the Program or any derivative work under copyright law:
darkhan@105: that is to say, a work containing the Program or a portion of it,
darkhan@105: either verbatim or with modifications and/or translated into another
darkhan@105: language. (Hereinafter, translation is included without limitation in
darkhan@105: the term "modification".) Each licensee is addressed as "you".
darkhan@105:
darkhan@105: Activities other than copying, distribution and modification are not
darkhan@105: covered by this License; they are outside its scope. The act of
darkhan@105: running the Program is not restricted, and the output from the Program
darkhan@105: is covered only if its contents constitute a work based on the
darkhan@105: Program (independent of having been made by running the Program).
darkhan@105: Whether that is true depends on what the Program does.
darkhan@105:
darkhan@105: 1. You may copy and distribute verbatim copies of the Program's
darkhan@105: source code as you receive it, in any medium, provided that you
darkhan@105: conspicuously and appropriately publish on each copy an appropriate
darkhan@105: copyright notice and disclaimer of warranty; keep intact all the
darkhan@105: notices that refer to this License and to the absence of any warranty;
darkhan@105: and give any other recipients of the Program a copy of this License
darkhan@105: along with the Program.
darkhan@105:
darkhan@105: You may charge a fee for the physical act of transferring a copy, and
darkhan@105: you may at your option offer warranty protection in exchange for a fee.
darkhan@105:
darkhan@105: 2. You may modify your copy or copies of the Program or any portion
darkhan@105: of it, thus forming a work based on the Program, and copy and
darkhan@105: distribute such modifications or work under the terms of Section 1
darkhan@105: above, provided that you also meet all of these conditions:
darkhan@105:
darkhan@105: a) You must cause the modified files to carry prominent notices
darkhan@105: stating that you changed the files and the date of any change.
darkhan@105:
darkhan@105: b) You must cause any work that you distribute or publish, that in
darkhan@105: whole or in part contains or is derived from the Program or any
darkhan@105: part thereof, to be licensed as a whole at no charge to all third
darkhan@105: parties under the terms of this License.
darkhan@105:
darkhan@105: c) If the modified program normally reads commands interactively
darkhan@105: when run, you must cause it, when started running for such
darkhan@105: interactive use in the most ordinary way, to print or display an
darkhan@105: announcement including an appropriate copyright notice and a
darkhan@105: notice that there is no warranty (or else, saying that you provide
darkhan@105: a warranty) and that users may redistribute the program under
darkhan@105: these conditions, and telling the user how to view a copy of this
darkhan@105: License. (Exception: if the Program itself is interactive but
darkhan@105: does not normally print such an announcement, your work based on
darkhan@105: the Program is not required to print an announcement.)
darkhan@105:
darkhan@105: These requirements apply to the modified work as a whole. If
darkhan@105: identifiable sections of that work are not derived from the Program,
darkhan@105: and can be reasonably considered independent and separate works in
darkhan@105: themselves, then this License, and its terms, do not apply to those
darkhan@105: sections when you distribute them as separate works. But when you
darkhan@105: distribute the same sections as part of a whole which is a work based
darkhan@105: on the Program, the distribution of the whole must be on the terms of
darkhan@105: this License, whose permissions for other licensees extend to the
darkhan@105: entire whole, and thus to each and every part regardless of who wrote it.
darkhan@105:
darkhan@105: Thus, it is not the intent of this section to claim rights or contest
darkhan@105: your rights to work written entirely by you; rather, the intent is to
darkhan@105: exercise the right to control the distribution of derivative or
darkhan@105: collective works based on the Program.
darkhan@105:
darkhan@105: In addition, mere aggregation of another work not based on the Program
darkhan@105: with the Program (or with a work based on the Program) on a volume of
darkhan@105: a storage or distribution medium does not bring the other work under
darkhan@105: the scope of this License.
darkhan@105:
darkhan@105: 3. You may copy and distribute the Program (or a work based on it,
darkhan@105: under Section 2) in object code or executable form under the terms of
darkhan@105: Sections 1 and 2 above provided that you also do one of the following:
darkhan@105:
darkhan@105: a) Accompany it with the complete corresponding machine-readable
darkhan@105: source code, which must be distributed under the terms of Sections
darkhan@105: 1 and 2 above on a medium customarily used for software interchange; or,
darkhan@105:
darkhan@105: b) Accompany it with a written offer, valid for at least three
darkhan@105: years, to give any third party, for a charge no more than your
darkhan@105: cost of physically performing source distribution, a complete
darkhan@105: machine-readable copy of the corresponding source code, to be
darkhan@105: distributed under the terms of Sections 1 and 2 above on a medium
darkhan@105: customarily used for software interchange; or,
darkhan@105:
darkhan@105: c) Accompany it with the information you received as to the offer
darkhan@105: to distribute corresponding source code. (This alternative is
darkhan@105: allowed only for noncommercial distribution and only if you
darkhan@105: received the program in object code or executable form with such
darkhan@105: an offer, in accord with Subsection b above.)
darkhan@105:
darkhan@105: The source code for a work means the preferred form of the work for
darkhan@105: making modifications to it. For an executable work, complete source
darkhan@105: code means all the source code for all modules it contains, plus any
darkhan@105: associated interface definition files, plus the scripts used to
darkhan@105: control compilation and installation of the executable. However, as a
darkhan@105: special exception, the source code distributed need not include
darkhan@105: anything that is normally distributed (in either source or binary
darkhan@105: form) with the major components (compiler, kernel, and so on) of the
darkhan@105: operating system on which the executable runs, unless that component
darkhan@105: itself accompanies the executable.
darkhan@105:
darkhan@105: If distribution of executable or object code is made by offering
darkhan@105: access to copy from a designated place, then offering equivalent
darkhan@105: access to copy the source code from the same place counts as
darkhan@105: distribution of the source code, even though third parties are not
darkhan@105: compelled to copy the source along with the object code.
darkhan@105:
darkhan@105: 4. You may not copy, modify, sublicense, or distribute the Program
darkhan@105: except as expressly provided under this License. Any attempt
darkhan@105: otherwise to copy, modify, sublicense or distribute the Program is
darkhan@105: void, and will automatically terminate your rights under this License.
darkhan@105: However, parties who have received copies, or rights, from you under
darkhan@105: this License will not have their licenses terminated so long as such
darkhan@105: parties remain in full compliance.
darkhan@105:
darkhan@105: 5. You are not required to accept this License, since you have not
darkhan@105: signed it. However, nothing else grants you permission to modify or
darkhan@105: distribute the Program or its derivative works. These actions are
darkhan@105: prohibited by law if you do not accept this License. Therefore, by
darkhan@105: modifying or distributing the Program (or any work based on the
darkhan@105: Program), you indicate your acceptance of this License to do so, and
darkhan@105: all its terms and conditions for copying, distributing or modifying
darkhan@105: the Program or works based on it.
darkhan@105:
darkhan@105: 6. Each time you redistribute the Program (or any work based on the
darkhan@105: Program), the recipient automatically receives a license from the
darkhan@105: original licensor to copy, distribute or modify the Program subject to
darkhan@105: these terms and conditions. You may not impose any further
darkhan@105: restrictions on the recipients' exercise of the rights granted herein.
darkhan@105: You are not responsible for enforcing compliance by third parties to
darkhan@105: this License.
darkhan@105:
darkhan@105: 7. If, as a consequence of a court judgment or allegation of patent
darkhan@105: infringement or for any other reason (not limited to patent issues),
darkhan@105: conditions are imposed on you (whether by court order, agreement or
darkhan@105: otherwise) that contradict the conditions of this License, they do not
darkhan@105: excuse you from the conditions of this License. If you cannot
darkhan@105: distribute so as to satisfy simultaneously your obligations under this
darkhan@105: License and any other pertinent obligations, then as a consequence you
darkhan@105: may not distribute the Program at all. For example, if a patent
darkhan@105: license would not permit royalty-free redistribution of the Program by
darkhan@105: all those who receive copies directly or indirectly through you, then
darkhan@105: the only way you could satisfy both it and this License would be to
darkhan@105: refrain entirely from distribution of the Program.
darkhan@105:
darkhan@105: If any portion of this section is held invalid or unenforceable under
darkhan@105: any particular circumstance, the balance of the section is intended to
darkhan@105: apply and the section as a whole is intended to apply in other
darkhan@105: circumstances.
darkhan@105:
darkhan@105: It is not the purpose of this section to induce you to infringe any
darkhan@105: patents or other property right claims or to contest validity of any
darkhan@105: such claims; this section has the sole purpose of protecting the
darkhan@105: integrity of the free software distribution system, which is
darkhan@105: implemented by public license practices. Many people have made
darkhan@105: generous contributions to the wide range of software distributed
darkhan@105: through that system in reliance on consistent application of that
darkhan@105: system; it is up to the author/donor to decide if he or she is willing
darkhan@105: to distribute software through any other system and a licensee cannot
darkhan@105: impose that choice.
darkhan@105:
darkhan@105: This section is intended to make thoroughly clear what is believed to
darkhan@105: be a consequence of the rest of this License.
darkhan@105:
darkhan@105: 8. If the distribution and/or use of the Program is restricted in
darkhan@105: certain countries either by patents or by copyrighted interfaces, the
darkhan@105: original copyright holder who places the Program under this License
darkhan@105: may add an explicit geographical distribution limitation excluding
darkhan@105: those countries, so that distribution is permitted only in or among
darkhan@105: countries not thus excluded. In such case, this License incorporates
darkhan@105: the limitation as if written in the body of this License.
darkhan@105:
darkhan@105: 9. The Free Software Foundation may publish revised and/or new versions
darkhan@105: of the General Public License from time to time. Such new versions will
darkhan@105: be similar in spirit to the present version, but may differ in detail to
darkhan@105: address new problems or concerns.
darkhan@105:
darkhan@105: Each version is given a distinguishing version number. If the Program
darkhan@105: specifies a version number of this License which applies to it and "any
darkhan@105: later version", you have the option of following the terms and conditions
darkhan@105: either of that version or of any later version published by the Free
darkhan@105: Software Foundation. If the Program does not specify a version number of
darkhan@105: this License, you may choose any version ever published by the Free Software
darkhan@105: Foundation.
darkhan@105:
darkhan@105: 10. If you wish to incorporate parts of the Program into other free
darkhan@105: programs whose distribution conditions are different, write to the author
darkhan@105: to ask for permission. For software which is copyrighted by the Free
darkhan@105: Software Foundation, write to the Free Software Foundation; we sometimes
darkhan@105: make exceptions for this. Our decision will be guided by the two goals
darkhan@105: of preserving the free status of all derivatives of our free software and
darkhan@105: of promoting the sharing and reuse of software generally.
darkhan@105:
darkhan@105: NO WARRANTY
darkhan@105:
darkhan@105: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
darkhan@105: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
darkhan@105: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
darkhan@105: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
darkhan@105: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
darkhan@105: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
darkhan@105: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
darkhan@105: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
darkhan@105: REPAIR OR CORRECTION.
darkhan@105:
darkhan@105: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
darkhan@105: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
darkhan@105: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
darkhan@105: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
darkhan@105: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
darkhan@105: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
darkhan@105: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
darkhan@105: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
darkhan@105: POSSIBILITY OF SUCH DAMAGES.
darkhan@105:
darkhan@105: END OF TERMS AND CONDITIONS
darkhan@105:
darkhan@105: How to Apply These Terms to Your New Programs
darkhan@105:
darkhan@105: If you develop a new program, and you want it to be of the greatest
darkhan@105: possible use to the public, the best way to achieve this is to make it
darkhan@105: free software which everyone can redistribute and change under these terms.
darkhan@105:
darkhan@105: To do so, attach the following notices to the program. It is safest
darkhan@105: to attach them to the start of each source file to most effectively
darkhan@105: convey the exclusion of warranty; and each file should have at least
darkhan@105: the "copyright" line and a pointer to where the full notice is found.
darkhan@105:
darkhan@105:
darkhan@105: Copyright (C)
darkhan@105:
darkhan@105: This program is free software; you can redistribute it and/or modify
darkhan@105: it under the terms of the GNU General Public License as published by
darkhan@105: the Free Software Foundation; either version 2 of the License, or
darkhan@105: (at your option) any later version.
darkhan@105:
darkhan@105: This program is distributed in the hope that it will be useful,
darkhan@105: but WITHOUT ANY WARRANTY; without even the implied warranty of
darkhan@105: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
darkhan@105: GNU General Public License for more details.
darkhan@105:
darkhan@105: You should have received a copy of the GNU General Public License along
darkhan@105: with this program; if not, write to the Free Software Foundation, Inc.,
darkhan@105: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
darkhan@105:
darkhan@105: Also add information on how to contact you by electronic and paper mail.
darkhan@105:
darkhan@105: If the program is interactive, make it output a short notice like this
darkhan@105: when it starts in an interactive mode:
darkhan@105:
darkhan@105: Gnomovision version 69, Copyright (C) year name of author
darkhan@105: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
darkhan@105: This is free software, and you are welcome to redistribute it
darkhan@105: under certain conditions; type `show c' for details.
darkhan@105:
darkhan@105: The hypothetical commands `show w' and `show c' should show the appropriate
darkhan@105: parts of the General Public License. Of course, the commands you use may
darkhan@105: be called something other than `show w' and `show c'; they could even be
darkhan@105: mouse-clicks or menu items--whatever suits your program.
darkhan@105:
darkhan@105: You should also get your employer (if you work as a programmer) or your
darkhan@105: school, if any, to sign a "copyright disclaimer" for the program, if
darkhan@105: necessary. Here is a sample; alter the names:
darkhan@105:
darkhan@105: Yoyodyne, Inc., hereby disclaims all copyright interest in the program
darkhan@105: `Gnomovision' (which makes passes at compilers) written by James Hacker.
darkhan@105:
darkhan@105: , 1 April 1989
darkhan@105: Ty Coon, President of Vice
darkhan@105:
darkhan@105: This General Public License does not permit incorporating your program into
darkhan@105: proprietary programs. If your program is a subroutine library, you may
darkhan@105: consider it more useful to permit linking proprietary applications with the
darkhan@105: library. If this is what you want to do, use the GNU Lesser General
darkhan@105: Public License instead of this License.
