     6  Everyone is permitted to copy and distribute verbatim copies
       
     7  of this license document, but changing it is not allowed.

     9 			    Preamble
       
    10 
       
    11   The licenses for most software are designed to take away your
       
    12 freedom to share and change it.  By contrast, the GNU General Public
       
    13 License is intended to guarantee your freedom to share and change free
       
    14 software--to make sure the software is free for all its users.  This
       
    15 General Public License applies to most of the Free Software
       
    16 Foundation's software and to any other program whose authors commit to
       
    17 using it.  (Some other Free Software Foundation software is covered by
       
    18 the GNU Library General Public License instead.)  You can apply it to
       
    19 your programs, too.
       
    20 
       
    21   When we speak of free software, we are referring to freedom, not
       
    22 price.  Our General Public Licenses are designed to make sure that you
       
    23 have the freedom to distribute copies of free software (and charge for
       
    24 this service if you wish), that you receive source code or can get it
       
    25 if you want it, that you can change the software or use pieces of it
       
    26 in 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
       
    29 anyone to deny you these rights or to ask you to surrender the rights.
       
    30 These restrictions translate to certain responsibilities for you if you
       
    31 distribute copies of the software, or if you modify it.
       
    32 
       
    33   For example, if you distribute copies of such a program, whether
       
    34 gratis or for a fee, you must give the recipients all the rights that
       
    35 you have.  You must make sure that they, too, receive or can get the
       
    36 source code.  And you must show them these terms so they know their
       
    37 rights.
       
    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,
       
    41 distribute and/or modify the software.
       
    42 
       
    43   Also, for each author's protection and ours, we want to make certain
       
    44 that everyone understands that there is no warranty for this free
       
    45 software.  If the software is modified by someone else and passed on, we
       
    46 want its recipients to know that what they have is not the original, so
       
    47 that any problems introduced by others will not reflect on the original
       
    48 authors' reputations.
       
    49 
       
    50   Finally, any free program is threatened constantly by software
       
    51 patents.  We wish to avoid the danger that redistributors of a free
       
    52 program will individually obtain patent licenses, in effect making the
       
    53 program proprietary.  To prevent this, we have made it clear that any
       
    54 patent must be licensed for everyone's free use or not licensed at all.
       
    55 
       
    56   The precise terms and conditions for copying, distribution and
       
    57 modification follow.

    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
       
    63 a notice placed by the copyright holder saying it may be distributed
       
    64 under the terms of this General Public License.  The "Program", below,
       
    65 refers to any such program or work, and a "work based on the Program"
       
    66 means either the Program or any derivative work under copyright law:
       
    67 that is to say, a work containing the Program or a portion of it,
       
    68 either verbatim or with modifications and/or translated into another
       
    69 language.  (Hereinafter, translation is included without limitation in
       
    70 the term "modification".)  Each licensee is addressed as "you".
       
    71 
       
    72 Activities other than copying, distribution and modification are not
       
    73 covered by this License; they are outside its scope.  The act of
       
    74 running the Program is not restricted, and the output from the Program
       
    75 is covered only if its contents constitute a work based on the
       
    76 Program (independent of having been made by running the Program).
       
    77 Whether that is true depends on what the Program does.
       
    78 
       
    79   1. You may copy and distribute verbatim copies of the Program's
       
    80 source code as you receive it, in any medium, provided that you
       
    81 conspicuously and appropriately publish on each copy an appropriate
       
    82 copyright notice and disclaimer of warranty; keep intact all the
       
    83 notices that refer to this License and to the absence of any warranty;
       
    84 and give any other recipients of the Program a copy of this License
       
    85 along with the Program.
       
    86 
       
    87 You may charge a fee for the physical act of transferring a copy, and
       
    88 you 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
       
    91 of it, thus forming a work based on the Program, and copy and
       
    92 distribute such modifications or work under the terms of Section 1
       
    93 above, 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 
       
   114 These requirements apply to the modified work as a whole.  If
       
   115 identifiable sections of that work are not derived from the Program,
       
   116 and can be reasonably considered independent and separate works in
       
   117 themselves, then this License, and its terms, do not apply to those
       
   118 sections when you distribute them as separate works.  But when you
       
   119 distribute the same sections as part of a whole which is a work based
       
   120 on the Program, the distribution of the whole must be on the terms of
       
   121 this License, whose permissions for other licensees extend to the
       
   122 entire whole, and thus to each and every part regardless of who wrote it.
       
   123 
       
   124 Thus, it is not the intent of this section to claim rights or contest
       
   125 your rights to work written entirely by you; rather, the intent is to
       
   126 exercise the right to control the distribution of derivative or
       
   127 collective works based on the Program.
       
   128 
       
   129 In addition, mere aggregation of another work not based on the Program
       
   130 with the Program (or with a work based on the Program) on a volume of
       
   131 a storage or distribution medium does not bring the other work under
       
   132 the scope of this License.
       
   133 
       
   134   3. You may copy and distribute the Program (or a work based on it,
       
   135 under Section 2) in object code or executable form under the terms of
       
   136 Sections 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 
       
   155 The source code for a work means the preferred form of the work for
       
   156 making modifications to it.  For an executable work, complete source
       
   157 code means all the source code for all modules it contains, plus any
       
   158 associated interface definition files, plus the scripts used to
       
   159 control compilation and installation of the executable.  However, as a
       
   160 special exception, the source code distributed need not include
       
   161 anything that is normally distributed (in either source or binary
       
   162 form) with the major components (compiler, kernel, and so on) of the
       
   163 operating system on which the executable runs, unless that component
       
   164 itself accompanies the executable.
       
   165 
       
   166 If distribution of executable or object code is made by offering
       
   167 access to copy from a designated place, then offering equivalent
       
   168 access to copy the source code from the same place counts as
       
   169 distribution of the source code, even though third parties are not
       
   170 compelled to copy the source along with the object code.
       
   171 
       
   172   4. You may not copy, modify, sublicense, or distribute the Program
       
   173 except as expressly provided under this License.  Any attempt
       
   174 otherwise to copy, modify, sublicense or distribute the Program is
       
   175 void, and will automatically terminate your rights under this License.
       
   176 However, parties who have received copies, or rights, from you under
       
   177 this License will not have their licenses terminated so long as such
       
   178 parties remain in full compliance.
       
   179 
       
   180   5. You are not required to accept this License, since you have not
       
   181 signed it.  However, nothing else grants you permission to modify or
       
   182 distribute the Program or its derivative works.  These actions are
       
   183 prohibited by law if you do not accept this License.  Therefore, by
       
   184 modifying or distributing the Program (or any work based on the
       
   185 Program), you indicate your acceptance of this License to do so, and
       
   186 all its terms and conditions for copying, distributing or modifying
       
   187 the Program or works based on it.
       
   188 
       
   189   6. Each time you redistribute the Program (or any work based on the
       
   190 Program), the recipient automatically receives a license from the
       
   191 original licensor to copy, distribute or modify the Program subject to
       
   192 these terms and conditions.  You may not impose any further
       
   193 restrictions on the recipients' exercise of the rights granted herein.
       
   194 You are not responsible for enforcing compliance by third parties to
       
   195 this License.
       
   196 
       
   197   7. If, as a consequence of a court judgment or allegation of patent
       
   198 infringement or for any other reason (not limited to patent issues),
       
   199 conditions are imposed on you (whether by court order, agreement or
       
   200 otherwise) that contradict the conditions of this License, they do not
       
   201 excuse you from the conditions of this License.  If you cannot
       
   202 distribute so as to satisfy simultaneously your obligations under this
       
   203 License and any other pertinent obligations, then as a consequence you
       
   204 may not distribute the Program at all.  For example, if a patent
       
   205 license would not permit royalty-free redistribution of the Program by
       
   206 all those who receive copies directly or indirectly through you, then
       
   207 the only way you could satisfy both it and this License would be to
       
   208 refrain entirely from distribution of the Program.
       
   209 
       
   210 If any portion of this section is held invalid or unenforceable under
       
   211 any particular circumstance, the balance of the section is intended to
       
   212 apply and the section as a whole is intended to apply in other
       
   213 circumstances.
       
   214 
       
   215 It is not the purpose of this section to induce you to infringe any
       
   216 patents or other property right claims or to contest validity of any
       
   217 such claims; this section has the sole purpose of protecting the
       
   218 integrity of the free software distribution system, which is
       
   219 implemented by public license practices.  Many people have made
       
   220 generous contributions to the wide range of software distributed
       
   221 through that system in reliance on consistent application of that
       
   222 system; it is up to the author/donor to decide if he or she is willing
       
   223 to distribute software through any other system and a licensee cannot
       
   224 impose that choice.
       
   225 
       
   226 This section is intended to make thoroughly clear what is believed to
       
   227 be a consequence of the rest of this License.
       
   228 
       
   229   8. If the distribution and/or use of the Program is restricted in
       
   230 certain countries either by patents or by copyrighted interfaces, the
       
   231 original copyright holder who places the Program under this License
       
   232 may add an explicit geographical distribution limitation excluding
       
   233 those countries, so that distribution is permitted only in or among
       
   234 countries not thus excluded.  In such case, this License incorporates
       
   235 the limitation as if written in the body of this License.
       
   236 
       
   237   9. The Free Software Foundation may publish revised and/or new versions
       
   238 of the General Public License from time to time.  Such new versions will
       
   239 be similar in spirit to the present version, but may differ in detail to
       
   240 address new problems or concerns.
       
   241 
       
   242 Each version is given a distinguishing version number.  If the Program
       
   243 specifies a version number of this License which applies to it and "any
       
   244 later version", you have the option of following the terms and conditions
       
   245 either of that version or of any later version published by the Free
       
   246 Software Foundation.  If the Program does not specify a version number of
       
   247 this License, you may choose any version ever published by the Free Software
       
   248 Foundation.
       
   249 
       
   250   10. If you wish to incorporate parts of the Program into other free
       
   251 programs whose distribution conditions are different, write to the author
       
   252 to ask for permission.  For software which is copyrighted by the Free
       
   253 Software Foundation, write to the Free Software Foundation; we sometimes
       
   254 make exceptions for this.  Our decision will be guided by the two goals
       
   255 of preserving the free status of all derivatives of our free software and
       
   256 of 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
       
   261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
       
   262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
       
   263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
       
   264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
       
   265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
       
   266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
       
   267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
       
   268 REPAIR OR CORRECTION.
       
   269 
       
   270   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
       
   272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
       
   273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
       
   274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
       
   275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
       
   276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
       
   277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
       
   278 POSSIBILITY 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
       
   285 possible use to the public, the best way to achieve this is to make it
       
   286 free 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
       
   289 to attach them to the start of each source file to most effectively
       
   290 convey the exclusion of warranty; and each file should have at least
       
   291 the "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.>

   313 If the program is interactive, make it output a short notice like this
       
   314 when it starts in an interactive mode:

   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 
       
   321 The hypothetical commands `show w' and `show c' should show the appropriate
       
   322 parts of the General Public License.  Of course, the commands you use may
       
   323 be called something other than `show w' and `show c'; they could even be
       
   324 mouse-clicks or menu items--whatever suits your program.
       
   325 
       
   326 You should also get your employer (if you work as a programmer) or your
       
   327 school, if any, to sign a "copyright disclaimer" for the program, if
       
   328 necessary.  Here is a sample; alter the names:

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