1.5 + Version 2, June 1991
1.6 +

1.8 + 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
1.9 + Everyone is permitted to copy and distribute verbatim copies
1.10 + of this license document, but changing it is not allowed.
1.11 +
1.12 + Preamble
1.13 +
1.14 + The licenses for most software are designed to take away your
1.15 +freedom to share and change it. By contrast, the GNU General Public
1.16 +License is intended to guarantee your freedom to share and change free
1.17 +software--to make sure the software is free for all its users. This
1.18 +General Public License applies to most of the Free Software
1.19 +Foundation's software and to any other program whose authors commit to
1.20 +using it. (Some other Free Software Foundation software is covered by
1.21 +the GNU Library General Public License instead.) You can apply it to
1.22 +your programs, too.
1.23 +
1.24 + When we speak of free software, we are referring to freedom, not
1.25 +price. Our General Public Licenses are designed to make sure that you
1.26 +have the freedom to distribute copies of free software (and charge for
1.27 +this service if you wish), that you receive source code or can get it
1.28 +if you want it, that you can change the software or use pieces of it
1.29 +in new free programs; and that you know you can do these things.
1.30 +
1.31 + To protect your rights, we need to make restrictions that forbid
1.32 +anyone to deny you these rights or to ask you to surrender the rights.
1.33 +These restrictions translate to certain responsibilities for you if you
1.34 +distribute copies of the software, or if you modify it.
1.35 +
1.36 + For example, if you distribute copies of such a program, whether
1.37 +gratis or for a fee, you must give the recipients all the rights that
1.38 +you have. You must make sure that they, too, receive or can get the
1.39 +source code. And you must show them these terms so they know their
1.40 +rights.
1.41 +
1.42 + We protect your rights with two steps: (1) copyright the software, and
1.43 +(2) offer you this license which gives you legal permission to copy,
1.44 +distribute and/or modify the software.
1.45 +
1.46 + Also, for each author's protection and ours, we want to make certain
1.47 +that everyone understands that there is no warranty for this free
1.48 +software. If the software is modified by someone else and passed on, we
1.49 +want its recipients to know that what they have is not the original, so
1.50 +that any problems introduced by others will not reflect on the original
1.51 +authors' reputations.
1.52 +
1.53 + Finally, any free program is threatened constantly by software
1.54 +patents. We wish to avoid the danger that redistributors of a free
1.55 +program will individually obtain patent licenses, in effect making the
1.56 +program proprietary. To prevent this, we have made it clear that any
1.57 +patent must be licensed for everyone's free use or not licensed at all.
1.58 +
1.59 + The precise terms and conditions for copying, distribution and
1.60 +modification follow.
1.61 +
1.62 + GNU GENERAL PUBLIC LICENSE
1.63 + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
1.64 +
1.65 + 0. This License applies to any program or other work which contains
1.66 +a notice placed by the copyright holder saying it may be distributed
1.67 +under the terms of this General Public License. The "Program", below,
1.68 +refers to any such program or work, and a "work based on the Program"
1.69 +means either the Program or any derivative work under copyright law:
1.70 +that is to say, a work containing the Program or a portion of it,
1.71 +either verbatim or with modifications and/or translated into another
1.72 +language. (Hereinafter, translation is included without limitation in
1.73 +the term "modification".) Each licensee is addressed as "you".
1.74 +
1.75 +Activities other than copying, distribution and modification are not
1.76 +covered by this License; they are outside its scope. The act of
1.77 +running the Program is not restricted, and the output from the Program
1.78 +is covered only if its contents constitute a work based on the
1.79 +Program (independent of having been made by running the Program).
1.80 +Whether that is true depends on what the Program does.
1.81 +
1.82 + 1. You may copy and distribute verbatim copies of the Program's
1.83 +source code as you receive it, in any medium, provided that you
1.84 +conspicuously and appropriately publish on each copy an appropriate
1.85 +copyright notice and disclaimer of warranty; keep intact all the
1.86 +notices that refer to this License and to the absence of any warranty;
1.87 +and give any other recipients of the Program a copy of this License
1.88 +along with the Program.
1.89 +
1.90 +You may charge a fee for the physical act of transferring a copy, and
1.91 +you may at your option offer warranty protection in exchange for a fee.
1.92 +
1.93 + 2. You may modify your copy or copies of the Program or any portion
1.94 +of it, thus forming a work based on the Program, and copy and
1.95 +distribute such modifications or work under the terms of Section 1
1.96 +above, provided that you also meet all of these conditions:
1.97 +
1.98 + a) You must cause the modified files to carry prominent notices
1.99 + stating that you changed the files and the date of any change.
1.100 +
1.101 + b) You must cause any work that you distribute or publish, that in
1.102 + whole or in part contains or is derived from the Program or any
1.103 + part thereof, to be licensed as a whole at no charge to all third
1.104 + parties under the terms of this License.
1.105 +
1.106 + c) If the modified program normally reads commands interactively
1.107 + when run, you must cause it, when started running for such
1.108 + interactive use in the most ordinary way, to print or display an
1.109 + announcement including an appropriate copyright notice and a
1.110 + notice that there is no warranty (or else, saying that you provide
1.111 + a warranty) and that users may redistribute the program under
1.112 + these conditions, and telling the user how to view a copy of this
1.113 + License. (Exception: if the Program itself is interactive but
1.114 + does not normally print such an announcement, your work based on
1.115 + the Program is not required to print an announcement.)
1.116 +
1.117 +These requirements apply to the modified work as a whole. If
1.118 +identifiable sections of that work are not derived from the Program,
1.119 +and can be reasonably considered independent and separate works in
1.120 +themselves, then this License, and its terms, do not apply to those
1.121 +sections when you distribute them as separate works. But when you
1.122 +distribute the same sections as part of a whole which is a work based
1.123 +on the Program, the distribution of the whole must be on the terms of
1.124 +this License, whose permissions for other licensees extend to the
1.125 +entire whole, and thus to each and every part regardless of who wrote it.
1.126 +
1.127 +Thus, it is not the intent of this section to claim rights or contest
1.128 +your rights to work written entirely by you; rather, the intent is to
1.129 +exercise the right to control the distribution of derivative or
1.130 +collective works based on the Program.
1.131 +
1.132 +In addition, mere aggregation of another work not based on the Program
1.133 +with the Program (or with a work based on the Program) on a volume of
1.134 +a storage or distribution medium does not bring the other work under
1.135 +the scope of this License.
1.136 +
1.137 + 3. You may copy and distribute the Program (or a work based on it,
1.138 +under Section 2) in object code or executable form under the terms of
1.139 +Sections 1 and 2 above provided that you also do one of the following:
1.140 +
1.141 + a) Accompany it with the complete corresponding machine-readable
1.142 + source code, which must be distributed under the terms of Sections
1.143 + 1 and 2 above on a medium customarily used for software interchange; or,
1.144 +
1.145 + b) Accompany it with a written offer, valid for at least three
1.146 + years, to give any third party, for a charge no more than your
1.147 + cost of physically performing source distribution, a complete
1.148 + machine-readable copy of the corresponding source code, to be
1.149 + distributed under the terms of Sections 1 and 2 above on a medium
1.150 + customarily used for software interchange; or,
1.151 +
1.152 + c) Accompany it with the information you received as to the offer
1.153 + to distribute corresponding source code. (This alternative is
1.154 + allowed only for noncommercial distribution and only if you
1.155 + received the program in object code or executable form with such
1.156 + an offer, in accord with Subsection b above.)
1.157 +
1.158 +The source code for a work means the preferred form of the work for
1.159 +making modifications to it. For an executable work, complete source
1.160 +code means all the source code for all modules it contains, plus any
1.161 +associated interface definition files, plus the scripts used to
1.162 +control compilation and installation of the executable. However, as a
1.163 +special exception, the source code distributed need not include
1.164 +anything that is normally distributed (in either source or binary
1.165 +form) with the major components (compiler, kernel, and so on) of the
1.166 +operating system on which the executable runs, unless that component
1.167 +itself accompanies the executable.
1.168 +
1.169 +If distribution of executable or object code is made by offering
1.170 +access to copy from a designated place, then offering equivalent
1.171 +access to copy the source code from the same place counts as
1.172 +distribution of the source code, even though third parties are not
1.173 +compelled to copy the source along with the object code.
1.174 +
1.175 + 4. You may not copy, modify, sublicense, or distribute the Program
1.176 +except as expressly provided under this License. Any attempt
1.177 +otherwise to copy, modify, sublicense or distribute the Program is
1.178 +void, and will automatically terminate your rights under this License.
1.179 +However, parties who have received copies, or rights, from you under
1.180 +this License will not have their licenses terminated so long as such
1.181 +parties remain in full compliance.
1.182 +
1.183 + 5. You are not required to accept this License, since you have not
1.184 +signed it. However, nothing else grants you permission to modify or
1.185 +distribute the Program or its derivative works. These actions are
1.186 +prohibited by law if you do not accept this License. Therefore, by
1.187 +modifying or distributing the Program (or any work based on the
1.188 +Program), you indicate your acceptance of this License to do so, and
1.189 +all its terms and conditions for copying, distributing or modifying
1.190 +the Program or works based on it.
1.191 +
1.192 + 6. Each time you redistribute the Program (or any work based on the
1.193 +Program), the recipient automatically receives a license from the
1.194 +original licensor to copy, distribute or modify the Program subject to
1.195 +these terms and conditions. You may not impose any further
1.196 +restrictions on the recipients' exercise of the rights granted herein.
1.197 +You are not responsible for enforcing compliance by third parties to
1.198 +this License.
1.199 +
1.200 + 7. If, as a consequence of a court judgment or allegation of patent
1.201 +infringement or for any other reason (not limited to patent issues),
1.202 +conditions are imposed on you (whether by court order, agreement or
1.203 +otherwise) that contradict the conditions of this License, they do not
1.204 +excuse you from the conditions of this License. If you cannot
1.205 +distribute so as to satisfy simultaneously your obligations under this
1.206 +License and any other pertinent obligations, then as a consequence you
1.207 +may not distribute the Program at all. For example, if a patent
1.208 +license would not permit royalty-free redistribution of the Program by
1.209 +all those who receive copies directly or indirectly through you, then
1.210 +the only way you could satisfy both it and this License would be to
1.211 +refrain entirely from distribution of the Program.
1.212 +
1.213 +If any portion of this section is held invalid or unenforceable under
1.214 +any particular circumstance, the balance of the section is intended to
1.215 +apply and the section as a whole is intended to apply in other
1.216 +circumstances.
1.217 +
1.218 +It is not the purpose of this section to induce you to infringe any
1.219 +patents or other property right claims or to contest validity of any
1.220 +such claims; this section has the sole purpose of protecting the
1.221 +integrity of the free software distribution system, which is
1.222 +implemented by public license practices. Many people have made
1.223 +generous contributions to the wide range of software distributed
1.224 +through that system in reliance on consistent application of that
1.225 +system; it is up to the author/donor to decide if he or she is willing
1.226 +to distribute software through any other system and a licensee cannot
1.227 +impose that choice.
1.228 +
1.229 +This section is intended to make thoroughly clear what is believed to
1.230 +be a consequence of the rest of this License.
1.231 +
1.232 + 8. If the distribution and/or use of the Program is restricted in
1.233 +certain countries either by patents or by copyrighted interfaces, the
1.234 +original copyright holder who places the Program under this License
1.235 +may add an explicit geographical distribution limitation excluding
1.236 +those countries, so that distribution is permitted only in or among
1.237 +countries not thus excluded. In such case, this License incorporates
1.238 +the limitation as if written in the body of this License.
1.239 +
1.240 + 9. The Free Software Foundation may publish revised and/or new versions
1.241 +of the General Public License from time to time. Such new versions will
1.242 +be similar in spirit to the present version, but may differ in detail to
1.243 +address new problems or concerns.
1.244 +
1.245 +Each version is given a distinguishing version number. If the Program
1.246 +specifies a version number of this License which applies to it and "any
1.247 +later version", you have the option of following the terms and conditions
1.248 +either of that version or of any later version published by the Free
1.249 +Software Foundation. If the Program does not specify a version number of
1.250 +this License, you may choose any version ever published by the Free Software
1.251 +Foundation.
1.252 +
1.253 + 10. If you wish to incorporate parts of the Program into other free
1.254 +programs whose distribution conditions are different, write to the author
1.255 +to ask for permission. For software which is copyrighted by the Free
1.256 +Software Foundation, write to the Free Software Foundation; we sometimes
1.257 +make exceptions for this. Our decision will be guided by the two goals
1.258 +of preserving the free status of all derivatives of our free software and
1.259 +of promoting the sharing and reuse of software generally.
1.260 +
1.261 + NO WARRANTY
1.262 +
1.263 + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
1.264 +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
1.265 +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
1.266 +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
1.267 +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
1.268 +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
1.269 +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
1.270 +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
1.271 +REPAIR OR CORRECTION.
1.272 +
1.273 + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
1.274 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
1.275 +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
1.276 +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
1.277 +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
1.278 +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
1.279 +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
1.280 +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
1.281 +POSSIBILITY OF SUCH DAMAGES.
1.282 +
1.283 + END OF TERMS AND CONDITIONS
1.284 +
1.285 + How to Apply These Terms to Your New Programs
1.286 +
1.287 + If you develop a new program, and you want it to be of the greatest
1.288 +possible use to the public, the best way to achieve this is to make it
1.289 +free software which everyone can redistribute and change under these terms.
1.290 +
1.291 + To do so, attach the following notices to the program. It is safest
1.292 +to attach them to the start of each source file to most effectively
1.293 +convey the exclusion of warranty; and each file should have at least
1.294 +the "copyright" line and a pointer to where the full notice is found.
1.295 +
1.296 + <one line to give the program's name and a brief idea of what it does.>
1.297 + Copyright (C) <year> <name of author>
1.298 +
1.299 + This program is free software; you can redistribute it and/or modify
1.300 + it under the terms of the GNU General Public License as published by
1.301 + the Free Software Foundation; either version 2 of the License, or
1.302 + (at your option) any later version.
1.303 +
1.304 + This program is distributed in the hope that it will be useful,
1.305 + but WITHOUT ANY WARRANTY; without even the implied warranty of
1.306 + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
1.307 + GNU General Public License for more details.
1.308 +
1.309 + You should have received a copy of the GNU General Public License
1.310 + along with this program; if not, write to the Free Software
1.311 + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
1.312 +
1.313 +
1.314 +Also add information on how to contact you by electronic and paper mail.
1.315 +
1.316 +If the program is interactive, make it output a short notice like this
1.317 +when it starts in an interactive mode:
1.318 +
1.319 + Gnomovision version 69, Copyright (C) year name of author
1.320 + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
1.321 + This is free software, and you are welcome to redistribute it
1.322 + under certain conditions; type `show c' for details.
1.323 +
1.324 +The hypothetical commands `show w' and `show c' should show the appropriate
1.325 +parts of the General Public License. Of course, the commands you use may
1.326 +be called something other than `show w' and `show c'; they could even be
1.327 +mouse-clicks or menu items--whatever suits your program.
1.328 +
1.329 +You should also get your employer (if you work as a programmer) or your
1.330 +school, if any, to sign a "copyright disclaimer" for the program, if
1.331 +necessary. Here is a sample; alter the names:
1.332 +
1.333 + Yoyodyne, Inc., hereby disclaims all copyright interest in the program
1.334 + `Gnomovision' (which makes passes at compilers) written by James Hacker.

1.338 +
1.339 +This General Public License does not permit incorporating your program into
1.340 +proprietary programs. If your program is a subroutine library, you may
1.341 +consider it more useful to permit linking proprietary applications with the
1.342 +library. If this is what you want to do, use the GNU Library General
1.343 +Public License instead of this License.
