   25 Everyone is permitted to copy and distribute verbatim copies
   26 of this license document, but changing it is not allowed.
   27 
   28 \centerline{{\sc Preamble}}
   29 
   30 The licenses for most software are designed to take away your
   31 freedom to share and change it.  By contrast, the GNU General Public
   32 License is intended to guarantee your freedom to share and change free
   33 software--to make sure the software is free for all its users.  This
   34 General Public License applies to most of the Free Software
   35 Foundation's software and to any other program whose authors commit to
   36 using it.  (Some other Free Software Foundation software is covered by
   37 the GNU Library General Public License instead.)  You can apply it to
   38 your programs, too.
   39 
   40 When we speak of free software, we are referring to freedom, not
   41 price.  Our General Public Licenses are designed to make sure that you
   42 have the freedom to distribute copies of free software (and charge for
   43 this service if you wish), that you receive source code or can get it
   44 if you want it, that you can change the software or use pieces of it
   45 in new free programs; and that you know you can do these things.
   46 
   47 To protect your rights, we need to make restrictions that forbid
   48 anyone to deny you these rights or to ask you to surrender the rights.
   49 These restrictions translate to certain responsibilities for you if you
   50 distribute copies of the software, or if you modify it.
   51 
   52 For example, if you distribute copies of such a program, whether
   53 gratis or for a fee, you must give the recipients all the rights that
   54 you have.  You must make sure that they, too, receive or can get the
   55 source code.  And you must show them these terms so they know their
   56 rights.
   57 
   58 We protect your rights with two steps: (1) copyright the software, and
   59 (2) offer you this license which gives you legal permission to copy,
   60 distribute and/or modify the software.
   61 
   62 Also, for each author's protection and ours, we want to make certain
   63 that everyone understands that there is no warranty for this free
   64 software.  If the software is modified by someone else and passed on, we
   65 want its recipients to know that what they have is not the original, so
   66 that any problems introduced by others will not reflect on the original
   67 authors' reputations.
   68 
   69 Finally, any free program is threatened constantly by software
   70 patents.  We wish to avoid the danger that redistributors of a free
   71 program will individually obtain patent licenses, in effect making the
   72 program proprietary.  To prevent this, we have made it clear that any
   73 patent must be licensed for everyone's free use or not licensed at all.
   74 
   75 The precise terms and conditions for copying, distribution and
   76 modification follow.
   77 		    
   78 \centerline{{\sc GNU GENERAL PUBLIC LICENSE}}
   79 \centerline{{\sc TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND 
   80 MODIFICATION}}
   81 
   82 \begin{enumerate}
   83 \item[0.] This License applies to any program or other work which contains
   84 a notice placed by the copyright holder saying it may be distributed
   85 under the terms of this General Public License.  The ``Program'', below,
   86 refers to any such program or work, and a ``work based on the Program''
   87 means either the Program or any derivative work under copyright law:
   88 that is to say, a work containing the Program or a portion of it,
   89 either verbatim or with modifications and/or translated into another
   90 language.  (Hereinafter, translation is included without limitation in
   91 the term ``modification''.)  Each licensee is addressed as ``you''.
   92 
   93 Activities other than copying, distribution and modification are not
   94 covered by this License; they are outside its scope.  The act of
   95 running the Program is not restricted, and the output from the Program
   96 is covered only if its contents constitute a work based on the
   97 Program (independent of having been made by running the Program).
   98 Whether that is true depends on what the Program does.
   99 
  100 \item[1.] You may copy and distribute verbatim copies of the Program's
  101 source code as you receive it, in any medium, provided that you
  102 conspicuously and appropriately publish on each copy an appropriate
  103 copyright notice and disclaimer of warranty; keep intact all the
  104 notices that refer to this License and to the absence of any warranty;
  105 and give any other recipients of the Program a copy of this License
  106 along with the Program.
  107 
  108 You may charge a fee for the physical act of transferring a copy, and
  109 you may at your option offer warranty protection in exchange for a fee.
  110 
  111 \item[2.] You may modify your copy or copies of the Program or any portion
  112 of it, thus forming a work based on the Program, and copy and
  113 distribute such modifications or work under the terms of Section 1
  114 above, provided that you also meet all of these conditions:
  115 
  116 \begin{enumerate}
  117 \item[a.] You must cause the modified files to carry prominent notices
  118     stating that you changed the files and the date of any change.
  119 
  120 \item[b.] You must cause any work that you distribute or publish, that in
  121     whole or in part contains or is derived from the Program or any
  122     part thereof, to be licensed as a whole at no charge to all third
  123     parties under the terms of this License.
  124 
  125 \item[c.] If the modified program normally reads commands interactively
  126     when run, you must cause it, when started running for such
  127     interactive use in the most ordinary way, to print or display an
  128     announcement including an appropriate copyright notice and a
  129     notice that there is no warranty (or else, saying that you provide
  130     a warranty) and that users may redistribute the program under
  131     these conditions, and telling the user how to view a copy of this
  132     License.  (Exception: if the Program itself is interactive but
  133     does not normally print such an announcement, your work based on
  134     the Program is not required to print an announcement.)
  135 \end{enumerate}
  136 
  137 These requirements apply to the modified work as a whole.  If
  138 identifiable sections of that work are not derived from the Program,
  139 and can be reasonably considered independent and separate works in
  140 themselves, then this License, and its terms, do not apply to those
  141 sections when you distribute them as separate works.  But when you
  142 distribute the same sections as part of a whole which is a work based
  143 on the Program, the distribution of the whole must be on the terms of
  144 this License, whose permissions for other licensees extend to the
  145 entire whole, and thus to each and every part regardless of who wrote it.
  146 
  147 Thus, it is not the intent of this section to claim rights or contest
  148 your rights to work written entirely by you; rather, the intent is to
  149 exercise the right to control the distribution of derivative or
  150 collective works based on the Program.
  151 
  152 In addition, mere aggregation of another work not based on the Program
  153 with the Program (or with a work based on the Program) on a volume of
  154 a storage or distribution medium does not bring the other work under
  155 the scope of this License.
  156 
  157 \item[3.] You may copy and distribute the Program (or a work based on it,
  158 under Section 2) in object code or executable form under the terms of
  159 Sections 1 and 2 above provided that you also do one of the following:
  160 
  161 \begin{enumerate}
  162 \item[a.] Accompany it with the complete corresponding machine-readable
  163     source code, which must be distributed under the terms of Sections
  164     1 and 2 above on a medium customarily used for software interchange; or,
  165 
  166 \item[b.] Accompany it with a written offer, valid for at least three
  167     years, to give any third party, for a charge no more than your
  168     cost of physically performing source distribution, a complete
  169     machine-readable copy of the corresponding source code, to be
  170     distributed under the terms of Sections 1 and 2 above on a medium
  171     customarily used for software interchange; or,
  172 
  173 \item[c.] Accompany it with the information you received as to the offer
  174     to distribute corresponding source code.  (This alternative is
  175     allowed only for noncommercial distribution and only if you
  176     received the program in object code or executable form with such
  177     an offer, in accord with Subsection b above.)
  178 \end{enumerate}
  179 
  180 The source code for a work means the preferred form of the work for
  181 making modifications to it.  For an executable work, complete source
  182 code means all the source code for all modules it contains, plus any
  183 associated interface definition files, plus the scripts used to
  184 control compilation and installation of the executable.  However, as a
  185 special exception, the source code distributed need not include
  186 anything that is normally distributed (in either source or binary
  187 form) with the major components (compiler, kernel, and so on) of the
  188 operating system on which the executable runs, unless that component
  189 itself accompanies the executable.
  190 
  191 If distribution of executable or object code is made by offering
  192 access to copy from a designated place, then offering equivalent
  193 access to copy the source code from the same place counts as
  194 distribution of the source code, even though third parties are not
  195 compelled to copy the source along with the object code.
  196   
  197 \item[4.] You may not copy, modify, sublicense, or distribute the Program
  198 except as expressly provided under this License.  Any attempt
  199 otherwise to copy, modify, sublicense or distribute the Program is
  200 void, and will automatically terminate your rights under this License.
  201 However, parties who have received copies, or rights, from you under
  202 this License will not have their licenses terminated so long as such
  203 parties remain in full compliance.
  204 
  205 \item[5.] You are not required to accept this License, since you have not
  206 signed it.  However, nothing else grants you permission to modify or
  207 distribute the Program or its derivative works.  These actions are
  208 prohibited by law if you do not accept this License.  Therefore, by
  209 modifying or distributing the Program (or any work based on the
  210 Program), you indicate your acceptance of this License to do so, and
  211 all its terms and conditions for copying, distributing or modifying
  212 the Program or works based on it.
  213 
  214 \item[6.] Each time you redistribute the Program (or any work based on the
  215 Program), the recipient automatically receives a license from the
  216 original licensor to copy, distribute or modify the Program subject to
  217 these terms and conditions.  You may not impose any further
  218 restrictions on the recipients' exercise of the rights granted herein.
  219 You are not responsible for enforcing compliance by third parties to
  220 this License.
  221 
  222 \item[7.] If, as a consequence of a court judgment or allegation of patent
  223 infringement or for any other reason (not limited to patent issues),
  224 conditions are imposed on you (whether by court order, agreement or
  225 otherwise) that contradict the conditions of this License, they do not
  226 excuse you from the conditions of this License.  If you cannot
  227 distribute so as to satisfy simultaneously your obligations under this
  228 License and any other pertinent obligations, then as a consequence you
  229 may not distribute the Program at all.  For example, if a patent
  230 license would not permit royalty-free redistribution of the Program by
  231 all those who receive copies directly or indirectly through you, then
  232 the only way you could satisfy both it and this License would be to
  233 refrain entirely from distribution of the Program.
  234 
  235 If any portion of this section is held invalid or unenforceable under
  236 any particular circumstance, the balance of the section is intended to
  237 apply and the section as a whole is intended to apply in other
  238 circumstances.
  239 
  240 It is not the purpose of this section to induce you to infringe any
  241 patents or other property right claims or to contest validity of any
  242 such claims; this section has the sole purpose of protecting the
  243 integrity of the free software distribution system, which is
  244 implemented by public license practices.  Many people have made
  245 generous contributions to the wide range of software distributed
  246 through that system in reliance on consistent application of that
  247 system; it is up to the author/donor to decide if he or she is willing
  248 to distribute software through any other system and a licensee cannot
  249 impose that choice.
  250 
  251 This section is intended to make thoroughly clear what is believed to
  252 be a consequence of the rest of this License.
  253 
  254 \item[8.] If the distribution and/or use of the Program is restricted in
  255 certain countries either by patents or by copyrighted interfaces, the
  256 original copyright holder who places the Program under this License
  257 may add an explicit geographical distribution limitation excluding
  258 those countries, so that distribution is permitted only in or among
  259 countries not thus excluded.  In such case, this License incorporates
  260 the limitation as if written in the body of this License.
  261 
  262 \item[9.] The Free Software Foundation may publish revised and/or new versions
  263 of the General Public License from time to time.  Such new versions will
  264 be similar in spirit to the present version, but may differ in detail to
  265 address new problems or concerns.
  266 
  267 Each version is given a distinguishing version number.  If the Program
  268 specifies a version number of this License which applies to it and ``any
  269 later version'', you have the option of following the terms and conditions
  270 either of that version or of any later version published by the Free
  271 Software Foundation.  If the Program does not specify a version number of
  272 this License, you may choose any version ever published by the Free Software
  273 Foundation.
  274 
  275 \item[10.] If you wish to incorporate parts of the Program into other free
  276 programs whose distribution conditions are different, write to the author
  277 to ask for permission.  For software which is copyrighted by the Free
  278 Software Foundation, write to the Free Software Foundation; we sometimes
  279 make exceptions for this.  Our decision will be guided by the two goals
  280 of preserving the free status of all derivatives of our free software and
  281 of promoting the sharing and reuse of software generally.
  282 
  283 \bigskip
  284 \centerline{{\sc NO WARRANTY}}
  285 
  286 \item[11.] BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
  287 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
  288 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
  289 PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
  290 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
  291 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
  292 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
  293 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
  294 REPAIR OR CORRECTION.
  295 
  296 \item[12.] IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  297 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
  298 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  299 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
  300 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
  301 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
  302 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
  303 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
  304 POSSIBILITY OF SUCH DAMAGES.
  305 
  306 \end{enumerate}
  307 \centerline{{\sc END OF TERMS AND CONDITIONS}}
  308 
  309 %\bigskip
  310 \centerline{{\sc Appendix: How to Apply These Terms to Your New Programs}}
  311 
  312 If you develop a new program, and you want it to be of the greatest
  313 possible use to the public, the best way to achieve this is to make it
  314 free software which everyone can redistribute and change under these terms.
  315 
  316 To do so, attach the following notices to the program.  It is safest
  317 to attach them to the start of each source file to most effectively
  318 convey the exclusion of warranty; and each file should have at least
  319 the ``copyright'' line and a pointer to where the full notice is found.
  320 
  321 \begin{quote}
  322     \cparam{one line to give the program's name and a brief idea of 
  323     what it does.}
  324     Copyright \copyright 19yy  \cparam{name of author}
  325 
  326     This program is free software; you can redistribute it and/or modify
  327     it under the terms of the GNU General Public License as published by
  328     the Free Software Foundation; either version 2 of the License, or
  329     (at your option) any later version.
  330 
  331     This program is distributed in the hope that it will be useful,
  332     but WITHOUT ANY WARRANTY; without even the implied warranty of
  333     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
  334     GNU General Public License for more details.
  335 
  336     You should have received a copy of the GNU General Public License
  337     along with this program; if not, write to the Free Software
  338     Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
  339 \end{quote}
  340 
  341 Also add information on how to contact you by electronic and paper mail.
  342 
  343 If the program is interactive, make it output a short notice like this
  344 when it starts in an interactive mode:
  345 
  346 \begin{tscreen}
  347     Gnomovision version 69, Copyright (C) 19yy name of author
  348     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  349     This is free software, and you are welcome to redistribute it
  350     under certain conditions; type `show c' for details.
  351 \end{tscreen}
  352 
  353 The hypothetical commands `show w' and `show c' should show the appropriate
  354 parts of the General Public License.  Of course, the commands you use may
  355 be called something other than `show w' and `show c'; they could even be
  356 mouse-clicks or menu items--whatever suits your program.
  357 
  358 You should also get your employer (if you work as a programmer) or your
  359 school, if any, to sign a ``copyright disclaimer'' for the program, if
  360 necessary.  Here is a sample; alter the names:
  361 
  362 \begin{quote}
  363   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  364   `Gnomovision' (which makes passes at compilers) written by James Hacker.

  368 \end{quote}
  369 
  370 This General Public License does not permit incorporating your program into
  371 proprietary programs.  If your program is a subroutine library, you may
  372 consider it more useful to permit linking proprietary applications with the
  373 library.  If this is what you want to do, use the GNU Library General
  374 Public License instead of this License.
