+
− 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 Lesser 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 Street, 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.

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