fp@667: 
fp@667: Everyone is permitted to copy and distribute verbatim copies of this license
fp@667: document, but changing it is not allowed.
fp@667: 
fp@667: Preamble
fp@667: 
fp@667: The licenses for most software are designed to take away your freedom to 
fp@667: share and change it. By contrast, the GNU General Public License is intended
fp@667: to guarantee your freedom to share and change free software--to make sure 
fp@667: the software is free for all its users. This General Public License applies 
fp@667: to most of the Free Software Foundation's software and to any other program 
fp@667: whose authors commit to using it. (Some other Free Software Foundation 
fp@667: software is covered by the GNU Library General Public License instead.) You 
fp@667: can apply it to your programs, too.
fp@667: 
fp@667: When we speak of free software, we are referring to freedom, not price. Our
fp@667: General Public Licenses are designed to make sure that you have the freedom 
fp@667: to distribute copies of free software (and charge for this service if you 
fp@667: wish), that you receive source code or can get it if you want it, that you 
fp@667: can change the software or use pieces of it in new free programs; and that 
fp@667: you know you can do these things.
fp@667: 
fp@667: To protect your rights, we need to make restrictions that forbid anyone to 
fp@667: deny you these rights or to ask you to surrender the rights. These 
fp@667: restrictions translate to certain responsibilities for you if you distribute
fp@667: copies of the software, or if you modify it.
fp@667: 
fp@667: For example, if you distribute copies of such a program, whether gratis or 
fp@667: for a fee, you must give the recipients all the rights that you have. You 
fp@667: must make sure that they, too, receive or can get the source code. And you 
fp@667: must show them these terms so they know their rights.
fp@667:  
fp@667: We protect your rights with two steps: (1) copyright the software, and (2) 
fp@667: offer you this license which gives you legal permission to copy, distribute 
fp@667: and/or modify the software. 
fp@667: 
fp@667: Also, for each author's protection and ours, we want to make certain that 
fp@667: everyone understands that there is no warranty for this free software. If 
fp@667: the software is modified by someone else and passed on, we want its 
fp@667: recipients to know that what they have is not the original, so that any 
fp@667: problems introduced by others will not reflect on the original authors' 
fp@667: reputations. 
fp@667: 
fp@667: Finally, any free program is threatened constantly by software patents. We 
fp@667: wish to avoid the danger that redistributors of a free program will 
fp@667: individually obtain patent licenses, in effect making the program 
fp@667: proprietary. To prevent this, we have made it clear that any patent must be 
fp@667: licensed for everyone's free use or not licensed at all. 
fp@667: 
fp@667: The precise terms and conditions for copying, distribution and modification 
fp@667: follow. 
fp@667: 
fp@667: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
fp@667: 
fp@667: 0. This License applies to any program or other work which contains a notice
fp@667:    placed by the copyright holder saying it may be distributed under the 
fp@667:    terms of this General Public License. The "Program", below, refers to any
fp@667:    such program or work, and a "work based on the Program" means either the 
fp@667:    Program or any derivative work under copyright law: that is to say, a 
fp@667:    work containing the Program or a portion of it, either verbatim or with 
fp@667:    modifications and/or translated into another language. (Hereinafter, 
fp@667:    translation is included without limitation in the term "modification".) 
fp@667:    Each licensee is addressed as "you". 
fp@667: 
fp@667:    Activities other than copying, distribution and modification are not 
fp@667:    covered by this License; they are outside its scope. The act of running 
fp@667:    the Program is not restricted, and the output from the Program is covered 
fp@667:    only if its contents constitute a work based on the Program (independent 
fp@667:    of having been made by running the Program). Whether that is true depends
fp@667:    on what the Program does. 
fp@667: 
fp@667: 1. You may copy and distribute verbatim copies of the Program's source code 
fp@667:    as you receive it, in any medium, provided that you conspicuously and 
fp@667:    appropriately publish on each copy an appropriate copyright notice and 
fp@667:    disclaimer of warranty; keep intact all the notices that refer to this 
fp@667:    License and to the absence of any warranty; and give any other recipients 
fp@667:    of the Program a copy of this License along with the Program. 
fp@667: 
fp@667:    You may charge a fee for the physical act of transferring a copy, and you 
fp@667:    may at your option offer warranty protection in exchange for a fee. 
fp@667: 
fp@667: 2. You may modify your copy or copies of the Program or any portion of it, 
fp@667:    thus forming a work based on the Program, and copy and distribute such 
fp@667:    modifications or work under the terms of Section 1 above, provided that 
fp@667:    you also meet all of these conditions: 
fp@667: 
fp@667:    * a) You must cause the modified files to carry prominent notices stating 
fp@667:         that you changed the files and the date of any change. 
fp@667: 
fp@667:    * b) You must cause any work that you distribute or publish, that in 
fp@667:         whole or in part contains or is derived from the Program or any part 
fp@667:         thereof, to be licensed as a whole at no charge to all third parties
fp@667:         under the terms of this License. 
fp@667: 
fp@667:    * c) If the modified program normally reads commands interactively when 
fp@667:         run, you must cause it, when started running for such interactive 
fp@667:         use in the most ordinary way, to print or display an announcement 
fp@667:         including an appropriate copyright notice and a notice that there is
fp@667:         no warranty (or else, saying that you provide a warranty) and that 
fp@667:         users may redistribute the program under these conditions, and 
fp@667:         telling the user how to view a copy of this License. (Exception: if 
fp@667:         the Program itself is interactive but does not normally print such 
fp@667:         an announcement, your work based on the Program is not required to 
fp@667:         print an announcement.) 
fp@667: 
fp@667:    These requirements apply to the modified work as a whole. If identifiable 
fp@667:    sections of that work are not derived from the Program, and can be 
fp@667:    reasonably considered independent and separate works in themselves, then 
fp@667:    this License, and its terms, do not apply to those sections when you 
fp@667:    distribute them as separate works. But when you distribute the same 
fp@667:    sections as part of a whole which is a work based on the Program, the 
fp@667:    distribution of the whole must be on the terms of this License, whose 
fp@667:    permissions for other licensees extend to the entire whole, and thus to 
fp@667:    each and every part regardless of who wrote it. 
fp@667: 
fp@667:    Thus, it is not the intent of this section to claim rights or contest 
fp@667:    your rights to work written entirely by you; rather, the intent is to 
fp@667:    exercise the right to control the distribution of derivative or 
fp@667:    collective works based on the Program. 
fp@667: 
fp@667:    In addition, mere aggregation of another work not based on the Program 
fp@667:    with the Program (or with a work based on the Program) on a volume of a 
fp@667:    storage or distribution medium does not bring the other work under the 
fp@667:    scope of this License. 
fp@667: 
fp@667: 3. You may copy and distribute the Program (or a work based on it, under 
fp@667:    Section 2) in object code or executable form under the terms of Sections 
fp@667:    1 and 2 above provided that you also do one of the following: 
fp@667: 
fp@667:    * a) Accompany it with the complete corresponding machine-readable source 
fp@667:         code, which must be distributed under the terms of Sections 1 and 2 
fp@667:         above on a medium customarily used for software interchange; or, 
fp@667: 
fp@667:    * b) Accompany it with a written offer, valid for at least three years, 
fp@667:         to give any third party, for a charge no more than your cost of 
fp@667:         physically performing source distribution, a complete machine-
fp@667:         readable copy of the corresponding source code, to be distributed 
fp@667:         under the terms of Sections 1 and 2 above on a medium customarily 
fp@667:         used for software interchange; or, 
fp@667: 
fp@667:    * c) Accompany it with the information you received as to the offer to 
fp@667:         distribute corresponding source code. (This alternative is allowed 
fp@667:         only for noncommercial distribution and only if you received the 
fp@667:         program in object code or executable form with such an offer, in 
fp@667:         accord with Subsection b above.) 
fp@667: 
fp@667:    The source code for a work means the preferred form of the work for 
fp@667:    making modifications to it. For an executable work, complete source code 
fp@667:    means all the source code for all modules it contains, plus any 
fp@667:    associated interface definition files, plus the scripts used to control 
fp@667:    compilation and installation of the executable. However, as a special 
fp@667:    exception, the source code distributed need not include anything that is 
fp@667:    normally distributed (in either source or binary form) with the major 
fp@667:    components (compiler, kernel, and so on) of the operating system on which
fp@667:    the executable runs, unless that component itself accompanies the 
fp@667:    executable. 
fp@667: 
fp@667:    If distribution of executable or object code is made by offering access 
fp@667:    to copy from a designated place, then offering equivalent access to copy 
fp@667:    the source code from the same place counts as distribution of the source 
fp@667:    code, even though third parties are not compelled to copy the source 
fp@667:    along with the object code. 
fp@667: 
fp@667: 4. You may not copy, modify, sublicense, or distribute the Program except as
fp@667:    expressly provided under this License. Any attempt otherwise to copy, 
fp@667:    modify, sublicense or distribute the Program is void, and will 
fp@667:    automatically terminate your rights under this License. However, parties 
fp@667:    who have received copies, or rights, from you under this License will not
fp@667:    have their licenses terminated so long as such parties remain in full 
fp@667:    compliance. 
fp@667: 
fp@667: 5. You are not required to accept this License, since you have not signed 
fp@667:    it. However, nothing else grants you permission to modify or distribute 
fp@667:    the Program or its derivative works. These actions are prohibited by law 
fp@667:    if you do not accept this License. Therefore, by modifying or 
fp@667:    distributing the Program (or any work based on the Program), you 
fp@667:    indicate your acceptance of this License to do so, and all its terms and
fp@667:    conditions for copying, distributing or modifying the Program or works 
fp@667:    based on it. 
fp@667: 
fp@667: 6. Each time you redistribute the Program (or any work based on the 
fp@667:    Program), the recipient automatically receives a license from the 
fp@667:    original licensor to copy, distribute or modify the Program subject to 
fp@667:    these terms and conditions. You may not impose any further restrictions 
fp@667:    on the recipients' exercise of the rights granted herein. You are not 
fp@667:    responsible for enforcing compliance by third parties to this License. 
fp@667: 
fp@667: 7. If, as a consequence of a court judgment or allegation of patent 
fp@667:    infringement or for any other reason (not limited to patent issues), 
fp@667:    conditions are imposed on you (whether by court order, agreement or 
fp@667:    otherwise) that contradict the conditions of this License, they do not 
fp@667:    excuse you from the conditions of this License. If you cannot distribute 
fp@667:    so as to satisfy simultaneously your obligations under this License and 
fp@667:    any other pertinent obligations, then as a consequence you may not 
fp@667:    distribute the Program at all. For example, if a patent license would 
fp@667:    not permit royalty-free redistribution of the Program by all those who 
fp@667:    receive copies directly or indirectly through you, then the only way you 
fp@667:    could satisfy both it and this License would be to refrain entirely from 
fp@667:    distribution of the Program. 
fp@667: 
fp@667:    If any portion of this section is held invalid or unenforceable under any
fp@667:    particular circumstance, the balance of the section is intended to apply
fp@667:    and the section as a whole is intended to apply in other circumstances. 
fp@667: 
fp@667:    It is not the purpose of this section to induce you to infringe any 
fp@667:    patents or other property right claims or to contest validity of any 
fp@667:    such claims; this section has the sole purpose of protecting the 
fp@667:    integrity of the free software distribution system, which is implemented 
fp@667:    by public license practices. Many people have made generous contributions
fp@667:    to the wide range of software distributed through that system in 
fp@667:    reliance on consistent application of that system; it is up to the 
fp@667:    author/donor to decide if he or she is willing to distribute software 
fp@667:    through any other system and a licensee cannot impose that choice. 
fp@667: 
fp@667:    This section is intended to make thoroughly clear what is believed to be 
fp@667:    a consequence of the rest of this License. 
fp@667: 
fp@667: 8. If the distribution and/or use of the Program is restricted in certain 
fp@667:    countries either by patents or by copyrighted interfaces, the original 
fp@667:    copyright holder who places the Program under this License may add an 
fp@667:    explicit geographical distribution limitation excluding those countries, 
fp@667:    so that distribution is permitted only in or among countries not thus 
fp@667:    excluded. In such case, this License incorporates the limitation as if 
fp@667:    written in the body of this License. 
fp@667: 
fp@667: 9. The Free Software Foundation may publish revised and/or new versions of 
fp@667:    the General Public License from time to time. Such new versions will be 
fp@667:    similar in spirit to the present version, but may differ in detail to 
fp@667:    address new problems or concerns. 
fp@667: 
fp@667:    Each version is given a distinguishing version number. If the Program 
fp@667:    specifies a version number of this License which applies to it and "any 
fp@667:    later version", you have the option of following the terms and 
fp@667:    conditions either of that version or of any later version published by 
fp@667:    the Free Software Foundation. If the Program does not specify a version 
fp@667:    number of this License, you may choose any version ever published by the 
fp@667:    Free Software Foundation. 
fp@667: 
fp@667: 10. If you wish to incorporate parts of the Program into other free programs
fp@667:     whose distribution conditions are different, write to the author to ask 
fp@667:     for permission. For software which is copyrighted by the Free Software 
fp@667:     Foundation, write to the Free Software Foundation; we sometimes make 
fp@667:     exceptions for this. Our decision will be guided by the two goals of 
fp@667:     preserving the free status of all derivatives of our free software and 
fp@667:     of promoting the sharing and reuse of software generally. 
fp@667: 
fp@667:    NO WARRANTY
fp@667: 
fp@667: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 
fp@667:     FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
fp@667:     OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
fp@667:     PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 
fp@667:     EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED 
fp@667:     WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 
fp@667:     ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 
fp@667:     YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 
fp@667:     NECESSARY SERVICING, REPAIR OR CORRECTION. 
fp@667: 
fp@667: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
fp@667:     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 
fp@667:     REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR 
fp@667:     DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 
fp@667:     DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 
fp@667:     (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 
fp@667:     INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF 
fp@667:     THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR 
fp@667:     OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
fp@667: 
fp@667: END OF TERMS AND CONDITIONS
fp@667: 
fp@667: How to Apply These Terms to Your New Programs
fp@667: 
fp@667: If you develop a new program, and you want it to be of the greatest 
fp@667: possible use to the public, the best way to achieve this is to make it free 
fp@667: software which everyone can redistribute and change under these terms. 
fp@667: 
fp@667: To do so, attach the following notices to the program. It is safest to 
fp@667: attach them to the start of each source file to most effectively convey the
fp@667: exclusion of warranty; and each file should have at least the "copyright" 
fp@667: line and a pointer to where the full notice is found. 
fp@667: 
fp@667: one line to give the program's name and an idea of what it does.
fp@667: Copyright (C) yyyy  name of author
fp@667: 
fp@667: This program is free software; you can redistribute it and/or modify it 
fp@667: under the terms of the GNU General Public License as published by the Free 
fp@667: Software Foundation; either version 2 of the License, or (at your option) 
fp@667: any later version.
fp@667: 
fp@667: This program is distributed in the hope that it will be useful, but WITHOUT 
fp@667: ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or 
fp@667: FITNESS FOR A PARTICULAR PURPOSE.  See the GNU General Public License for 
fp@667: more details.
fp@667: 
fp@667: You should have received a copy of the GNU General Public License along with
fp@667: this program; if not, write to the Free Software Foundation, Inc., 59 
fp@667: Temple Place - Suite 330, Boston, MA  02111-1307, USA.
fp@667: 
fp@667: Also add information on how to contact you by electronic and paper mail. 
fp@667: 
fp@667: If the program is interactive, make it output a short notice like this when 
fp@667: it starts in an interactive mode: 
fp@667: 
fp@667: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes 
fp@667: with ABSOLUTELY NO WARRANTY; for details type 'show w'.  This is free 
fp@667: software, and you are welcome to redistribute it under certain conditions; 
fp@667: type 'show c' for details.
fp@667: 
fp@667: The hypothetical commands 'show w' and 'show c' should show the appropriate 
fp@667: parts of the General Public License. Of course, the commands you use may be 
fp@667: called something other than 'show w' and 'show c'; they could even be 
fp@667: mouse-clicks or menu items--whatever suits your program. 
fp@667: 
fp@667: You should also get your employer (if you work as a programmer) or your 
fp@667: school, if any, to sign a "copyright disclaimer" for the program, if 
fp@667: necessary. Here is a sample; alter the names: 
fp@667: 
fp@667: Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
fp@667: 'Gnomovision' (which makes passes at compilers) written by James Hacker.

fp@667: Ty Coon, President of Vice
fp@667: 
fp@667: This General Public License does not permit incorporating your program into 
fp@667: proprietary programs. If your program is a subroutine library, you may 
fp@667: consider it more useful to permit linking proprietary applications with the 
fp@667: library. If this is what you want to do, use the GNU Library General Public 
fp@667: License instead of this License.
