  1 + GNU GENERAL PUBLIC LICENSE
  2 + Version 2, June 1991
  3 +
  4 + Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
  5 + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
  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
  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 Lesser 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.
  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
  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.>
  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 along
  307 + with this program; if not, write to the Free Software Foundation, Inc.,
  308 + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
  309 +
  310 +Also add information on how to contact you by electronic and paper mail.
  311 +
  312 +If the program is interactive, make it output a short notice like this
  313 +when it starts in an interactive mode:
  314 +
  315 + Gnomovision version 69, Copyright (C) year name of author
  316 + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  317 + This is free software, and you are welcome to redistribute it
  318 + under certain conditions; type `show c' for details.
  319 +
  320 +The hypothetical commands `show w' and `show c' should show the appropriate
  321 +parts of the General Public License. Of course, the commands you use may
  322 +be called something other than `show w' and `show c'; they could even be
  323 +mouse-clicks or menu items--whatever suits your program.
  324 +
  325 +You should also get your employer (if you work as a programmer) or your
  326 +school, if any, to sign a "copyright disclaimer" for the program, if
  327 +necessary. Here is a sample; alter the names:
  328 +
  329 + Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  330 + `Gnomovision' (which makes passes at compilers) written by James Hacker.
  331 +
  332 + <signature of Ty Coon>, 1 April 1989
  333 + Ty Coon, President of Vice
  334 +
  335 +This General Public License does not permit incorporating your program into
  336 +proprietary programs. If your program is a subroutine library, you may
  337 +consider it more useful to permit linking proprietary applications with the
  338 +library. If this is what you want to do, use the GNU Lesser General
  339 +Public License instead of this License.
