      6 Everyone is permitted to copy and distribute verbatim copies
      7 of this license document, but changing it is not allowed.
      8
      9			    Preamble
     10
     11  The licenses for most software are designed to take away your
     12freedom to share and change it.  By contrast, the GNU General Public
     13License is intended to guarantee your freedom to share and change free
     14software--to make sure the software is free for all its users.  This
     15General Public License applies to most of the Free Software
     16Foundation's software and to any other program whose authors commit to
     17using it.  (Some other Free Software Foundation software is covered by
     18the GNU Library General Public License instead.)  You can apply it to
     19your programs, too.
     20
     21  When we speak of free software, we are referring to freedom, not
     22price.  Our General Public Licenses are designed to make sure that you
     23have the freedom to distribute copies of free software (and charge for
     24this service if you wish), that you receive source code or can get it
     25if you want it, that you can change the software or use pieces of it
     26in new free programs; and that you know you can do these things.
     27
     28  To protect your rights, we need to make restrictions that forbid
     29anyone to deny you these rights or to ask you to surrender the rights.
     30These restrictions translate to certain responsibilities for you if you
     31distribute copies of the software, or if you modify it.
     32
     33  For example, if you distribute copies of such a program, whether
     34gratis or for a fee, you must give the recipients all the rights that
     35you have.  You must make sure that they, too, receive or can get the
     36source code.  And you must show them these terms so they know their
     37rights.
     38
     39  We protect your rights with two steps: (1) copyright the software, and
     40(2) offer you this license which gives you legal permission to copy,
     41distribute and/or modify the software.
     42
     43  Also, for each author's protection and ours, we want to make certain
     44that everyone understands that there is no warranty for this free
     45software.  If the software is modified by someone else and passed on, we
     46want its recipients to know that what they have is not the original, so
     47that any problems introduced by others will not reflect on the original
     48authors' reputations.
     49
     50  Finally, any free program is threatened constantly by software
     51patents.  We wish to avoid the danger that redistributors of a free
     52program will individually obtain patent licenses, in effect making the
     53program proprietary.  To prevent this, we have made it clear that any
     54patent must be licensed for everyone's free use or not licensed at all.
     55
     56  The precise terms and conditions for copying, distribution and
     57modification follow.
     58
     59		    GNU GENERAL PUBLIC LICENSE
     60   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
     61
     62  0. This License applies to any program or other work which contains
     63a notice placed by the copyright holder saying it may be distributed
     64under the terms of this General Public License.  The "Program", below,
     65refers to any such program or work, and a "work based on the Program"
     66means either the Program or any derivative work under copyright law:
     67that is to say, a work containing the Program or a portion of it,
     68either verbatim or with modifications and/or translated into another
     69language.  (Hereinafter, translation is included without limitation in
     70the term "modification".)  Each licensee is addressed as "you".
     71
     72Activities other than copying, distribution and modification are not
     73covered by this License; they are outside its scope.  The act of
     74running the Program is not restricted, and the output from the Program
     75is covered only if its contents constitute a work based on the
     76Program (independent of having been made by running the Program).
     77Whether that is true depends on what the Program does.
     78
     79  1. You may copy and distribute verbatim copies of the Program's
     80source code as you receive it, in any medium, provided that you
     81conspicuously and appropriately publish on each copy an appropriate
     82copyright notice and disclaimer of warranty; keep intact all the
     83notices that refer to this License and to the absence of any warranty;
     84and give any other recipients of the Program a copy of this License
     85along with the Program.
     86
     87You may charge a fee for the physical act of transferring a copy, and
     88you may at your option offer warranty protection in exchange for a fee.
     89
     90  2. You may modify your copy or copies of the Program or any portion
     91of it, thus forming a work based on the Program, and copy and
     92distribute such modifications or work under the terms of Section 1
     93above, provided that you also meet all of these conditions:
     94
     95    a) You must cause the modified files to carry prominent notices
     96    stating that you changed the files and the date of any change.
     97
     98    b) You must cause any work that you distribute or publish, that in
     99    whole or in part contains or is derived from the Program or any
    100    part thereof, to be licensed as a whole at no charge to all third
    101    parties under the terms of this License.
    102
    103    c) If the modified program normally reads commands interactively
    104    when run, you must cause it, when started running for such
    105    interactive use in the most ordinary way, to print or display an
    106    announcement including an appropriate copyright notice and a
    107    notice that there is no warranty (or else, saying that you provide
    108    a warranty) and that users may redistribute the program under
    109    these conditions, and telling the user how to view a copy of this
    110    License.  (Exception: if the Program itself is interactive but
    111    does not normally print such an announcement, your work based on
    112    the Program is not required to print an announcement.)
    113
    114These requirements apply to the modified work as a whole.  If
    115identifiable sections of that work are not derived from the Program,
    116and can be reasonably considered independent and separate works in
    117themselves, then this License, and its terms, do not apply to those
    118sections when you distribute them as separate works.  But when you
    119distribute the same sections as part of a whole which is a work based
    120on the Program, the distribution of the whole must be on the terms of
    121this License, whose permissions for other licensees extend to the
    122entire whole, and thus to each and every part regardless of who wrote it.
    123
    124Thus, it is not the intent of this section to claim rights or contest
    125your rights to work written entirely by you; rather, the intent is to
    126exercise the right to control the distribution of derivative or
    127collective works based on the Program.
    128
    129In addition, mere aggregation of another work not based on the Program
    130with the Program (or with a work based on the Program) on a volume of
    131a storage or distribution medium does not bring the other work under
    132the scope of this License.
    133
    134  3. You may copy and distribute the Program (or a work based on it,
    135under Section 2) in object code or executable form under the terms of
    136Sections 1 and 2 above provided that you also do one of the following:
    137
    138    a) Accompany it with the complete corresponding machine-readable
    139    source code, which must be distributed under the terms of Sections
    140    1 and 2 above on a medium customarily used for software interchange; or,
    141
    142    b) Accompany it with a written offer, valid for at least three
    143    years, to give any third party, for a charge no more than your
    144    cost of physically performing source distribution, a complete
    145    machine-readable copy of the corresponding source code, to be
    146    distributed under the terms of Sections 1 and 2 above on a medium
    147    customarily used for software interchange; or,
    148
    149    c) Accompany it with the information you received as to the offer
    150    to distribute corresponding source code.  (This alternative is
    151    allowed only for noncommercial distribution and only if you
    152    received the program in object code or executable form with such
    153    an offer, in accord with Subsection b above.)
    154
    155The source code for a work means the preferred form of the work for
    156making modifications to it.  For an executable work, complete source
    157code means all the source code for all modules it contains, plus any
    158associated interface definition files, plus the scripts used to
    159control compilation and installation of the executable.  However, as a
    160special exception, the source code distributed need not include
    161anything that is normally distributed (in either source or binary
    162form) with the major components (compiler, kernel, and so on) of the
    163operating system on which the executable runs, unless that component
    164itself accompanies the executable.
    165
    166If distribution of executable or object code is made by offering
    167access to copy from a designated place, then offering equivalent
    168access to copy the source code from the same place counts as
    169distribution of the source code, even though third parties are not
    170compelled to copy the source along with the object code.
    171
    172  4. You may not copy, modify, sublicense, or distribute the Program
    173except as expressly provided under this License.  Any attempt
    174otherwise to copy, modify, sublicense or distribute the Program is
    175void, and will automatically terminate your rights under this License.
    176However, parties who have received copies, or rights, from you under
    177this License will not have their licenses terminated so long as such
    178parties remain in full compliance.
    179
    180  5. You are not required to accept this License, since you have not
    181signed it.  However, nothing else grants you permission to modify or
    182distribute the Program or its derivative works.  These actions are
    183prohibited by law if you do not accept this License.  Therefore, by
    184modifying or distributing the Program (or any work based on the
    185Program), you indicate your acceptance of this License to do so, and
    186all its terms and conditions for copying, distributing or modifying
    187the Program or works based on it.
    188
    189  6. Each time you redistribute the Program (or any work based on the
    190Program), the recipient automatically receives a license from the
    191original licensor to copy, distribute or modify the Program subject to
    192these terms and conditions.  You may not impose any further
    193restrictions on the recipients' exercise of the rights granted herein.
    194You are not responsible for enforcing compliance by third parties to
    195this License.
    196
    197  7. If, as a consequence of a court judgment or allegation of patent
    198infringement or for any other reason (not limited to patent issues),
    199conditions are imposed on you (whether by court order, agreement or
    200otherwise) that contradict the conditions of this License, they do not
    201excuse you from the conditions of this License.  If you cannot
    202distribute so as to satisfy simultaneously your obligations under this
    203License and any other pertinent obligations, then as a consequence you
    204may not distribute the Program at all.  For example, if a patent
    205license would not permit royalty-free redistribution of the Program by
    206all those who receive copies directly or indirectly through you, then
    207the only way you could satisfy both it and this License would be to
    208refrain entirely from distribution of the Program.
    209
    210If any portion of this section is held invalid or unenforceable under
    211any particular circumstance, the balance of the section is intended to
    212apply and the section as a whole is intended to apply in other
    213circumstances.
    214
    215It is not the purpose of this section to induce you to infringe any
    216patents or other property right claims or to contest validity of any
    217such claims; this section has the sole purpose of protecting the
    218integrity of the free software distribution system, which is
    219implemented by public license practices.  Many people have made
    220generous contributions to the wide range of software distributed
    221through that system in reliance on consistent application of that
    222system; it is up to the author/donor to decide if he or she is willing
    223to distribute software through any other system and a licensee cannot
    224impose that choice.
    225
    226This section is intended to make thoroughly clear what is believed to
    227be a consequence of the rest of this License.
    228
    229  8. If the distribution and/or use of the Program is restricted in
    230certain countries either by patents or by copyrighted interfaces, the
    231original copyright holder who places the Program under this License
    232may add an explicit geographical distribution limitation excluding
    233those countries, so that distribution is permitted only in or among
    234countries not thus excluded.  In such case, this License incorporates
    235the limitation as if written in the body of this License.
    236
    237  9. The Free Software Foundation may publish revised and/or new versions
    238of the General Public License from time to time.  Such new versions will
    239be similar in spirit to the present version, but may differ in detail to
    240address new problems or concerns.
    241
    242Each version is given a distinguishing version number.  If the Program
    243specifies a version number of this License which applies to it and "any
    244later version", you have the option of following the terms and conditions
    245either of that version or of any later version published by the Free
    246Software Foundation.  If the Program does not specify a version number of
    247this License, you may choose any version ever published by the Free Software
    248Foundation.
    249
    250  10. If you wish to incorporate parts of the Program into other free
    251programs whose distribution conditions are different, write to the author
    252to ask for permission.  For software which is copyrighted by the Free
    253Software Foundation, write to the Free Software Foundation; we sometimes
    254make exceptions for this.  Our decision will be guided by the two goals
    255of preserving the free status of all derivatives of our free software and
    256of promoting the sharing and reuse of software generally.
    257
    258			    NO WARRANTY
    259
    260  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
    261FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
    262OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
    263PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
    264OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
    265MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
    266TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
    267PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
    268REPAIR OR CORRECTION.
    269
    270  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    271WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
    272REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
    273INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
    274OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
    275TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
    276YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
    277PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
    278POSSIBILITY OF SUCH DAMAGES.
    279
    280		     END OF TERMS AND CONDITIONS
    281
    282	    How to Apply These Terms to Your New Programs
    283
    284  If you develop a new program, and you want it to be of the greatest
    285possible use to the public, the best way to achieve this is to make it
    286free software which everyone can redistribute and change under these terms.
    287
    288  To do so, attach the following notices to the program.  It is safest
    289to attach them to the start of each source file to most effectively
    290convey the exclusion of warranty; and each file should have at least
    291the "copyright" line and a pointer to where the full notice is found.
    292
    293    <one line to give the program's name and a brief idea of what it does.>
    294    Copyright (C) <year>  <name of author>
    295
    296    This program is free software; you can redistribute it and/or modify
    297    it under the terms of the GNU General Public License as published by
    298    the Free Software Foundation; either version 2 of the License, or
    299    (at your option) any later version.
    300
    301    This program is distributed in the hope that it will be useful,
    302    but WITHOUT ANY WARRANTY; without even the implied warranty of
    303    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    304    GNU General Public License for more details.
    305
    306    You should have received a copy of the GNU General Public License
    307    along with this program; if not, write to the Free Software
    308    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301 USA
    309
    310
    311Also add information on how to contact you by electronic and paper mail.
    312
    313If the program is interactive, make it output a short notice like this
    314when it starts in an interactive mode:
    315
    316    Gnomovision version 69, Copyright (C) year  name of author
    317    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    318    This is free software, and you are welcome to redistribute it
    319    under certain conditions; type `show c' for details.
    320
    321The hypothetical commands `show w' and `show c' should show the appropriate
    322parts of the General Public License.  Of course, the commands you use may
    323be called something other than `show w' and `show c'; they could even be
    324mouse-clicks or menu items--whatever suits your program.
    325
    326You should also get your employer (if you work as a programmer) or your
    327school, if any, to sign a "copyright disclaimer" for the program, if
    328necessary.  Here is a sample; alter the names:
    329
    330  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
    331  `Gnomovision' (which makes passes at compilers) written by James Hacker.

    335
    336This General Public License does not permit incorporating your program into
    337proprietary programs.  If your program is a subroutine library, you may
    338consider it more useful to permit linking proprietary applications with the
    339library.  If this is what you want to do, use the GNU Library General
    340Public License instead of this License.
