darkhan@105 1 GNU GENERAL PUBLIC LICENSE
darkhan@105 2 Version 2, June 1991
darkhan@105 3
darkhan@105 4 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
darkhan@105 5 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
darkhan@105 6 Everyone is permitted to copy and distribute verbatim copies
darkhan@105 7 of this license document, but changing it is not allowed.
darkhan@105 8
darkhan@105 9 Preamble
darkhan@105 10
darkhan@105 11 The licenses for most software are designed to take away your
darkhan@105 12 freedom to share and change it. By contrast, the GNU General Public
darkhan@105 13 License is intended to guarantee your freedom to share and change free
darkhan@105 14 software--to make sure the software is free for all its users. This
darkhan@105 15 General Public License applies to most of the Free Software
darkhan@105 16 Foundation's software and to any other program whose authors commit to
darkhan@105 17 using it. (Some other Free Software Foundation software is covered by
darkhan@105 18 the GNU Lesser General Public License instead.) You can apply it to
darkhan@105 19 your programs, too.
darkhan@105 20
darkhan@105 21 When we speak of free software, we are referring to freedom, not
darkhan@105 22 price. Our General Public Licenses are designed to make sure that you
darkhan@105 23 have the freedom to distribute copies of free software (and charge for
darkhan@105 24 this service if you wish), that you receive source code or can get it
darkhan@105 25 if you want it, that you can change the software or use pieces of it
darkhan@105 26 in new free programs; and that you know you can do these things.
darkhan@105 27
darkhan@105 28 To protect your rights, we need to make restrictions that forbid
darkhan@105 29 anyone to deny you these rights or to ask you to surrender the rights.
darkhan@105 30 These restrictions translate to certain responsibilities for you if you
darkhan@105 31 distribute copies of the software, or if you modify it.
darkhan@105 32
darkhan@105 33 For example, if you distribute copies of such a program, whether
darkhan@105 34 gratis or for a fee, you must give the recipients all the rights that
darkhan@105 35 you have. You must make sure that they, too, receive or can get the
darkhan@105 36 source code. And you must show them these terms so they know their
darkhan@105 37 rights.
darkhan@105 38
darkhan@105 39 We protect your rights with two steps: (1) copyright the software, and
darkhan@105 40 (2) offer you this license which gives you legal permission to copy,
darkhan@105 41 distribute and/or modify the software.
darkhan@105 42
darkhan@105 43 Also, for each author's protection and ours, we want to make certain
darkhan@105 44 that everyone understands that there is no warranty for this free
darkhan@105 45 software. If the software is modified by someone else and passed on, we
darkhan@105 46 want its recipients to know that what they have is not the original, so
darkhan@105 47 that any problems introduced by others will not reflect on the original
darkhan@105 48 authors' reputations.
darkhan@105 49
darkhan@105 50 Finally, any free program is threatened constantly by software
darkhan@105 51 patents. We wish to avoid the danger that redistributors of a free
darkhan@105 52 program will individually obtain patent licenses, in effect making the
darkhan@105 53 program proprietary. To prevent this, we have made it clear that any
darkhan@105 54 patent must be licensed for everyone's free use or not licensed at all.
darkhan@105 55
darkhan@105 56 The precise terms and conditions for copying, distribution and
darkhan@105 57 modification follow.
darkhan@105 58
darkhan@105 59 GNU GENERAL PUBLIC LICENSE
darkhan@105 60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
darkhan@105 61
darkhan@105 62 0. This License applies to any program or other work which contains
darkhan@105 63 a notice placed by the copyright holder saying it may be distributed
darkhan@105 64 under the terms of this General Public License. The "Program", below,
darkhan@105 65 refers to any such program or work, and a "work based on the Program"
darkhan@105 66 means either the Program or any derivative work under copyright law:
darkhan@105 67 that is to say, a work containing the Program or a portion of it,
darkhan@105 68 either verbatim or with modifications and/or translated into another
darkhan@105 69 language. (Hereinafter, translation is included without limitation in
darkhan@105 70 the term "modification".) Each licensee is addressed as "you".
darkhan@105 71
darkhan@105 72 Activities other than copying, distribution and modification are not
darkhan@105 73 covered by this License; they are outside its scope. The act of
darkhan@105 74 running the Program is not restricted, and the output from the Program
darkhan@105 75 is covered only if its contents constitute a work based on the
darkhan@105 76 Program (independent of having been made by running the Program).
darkhan@105 77 Whether that is true depends on what the Program does.
darkhan@105 78
darkhan@105 79 1. You may copy and distribute verbatim copies of the Program's
darkhan@105 80 source code as you receive it, in any medium, provided that you
darkhan@105 81 conspicuously and appropriately publish on each copy an appropriate
darkhan@105 82 copyright notice and disclaimer of warranty; keep intact all the
darkhan@105 83 notices that refer to this License and to the absence of any warranty;
darkhan@105 84 and give any other recipients of the Program a copy of this License
darkhan@105 85 along with the Program.
darkhan@105 86
darkhan@105 87 You may charge a fee for the physical act of transferring a copy, and
darkhan@105 88 you may at your option offer warranty protection in exchange for a fee.
darkhan@105 89
darkhan@105 90 2. You may modify your copy or copies of the Program or any portion
darkhan@105 91 of it, thus forming a work based on the Program, and copy and
darkhan@105 92 distribute such modifications or work under the terms of Section 1
darkhan@105 93 above, provided that you also meet all of these conditions:
darkhan@105 94
darkhan@105 95 a) You must cause the modified files to carry prominent notices
darkhan@105 96 stating that you changed the files and the date of any change.
darkhan@105 97
darkhan@105 98 b) You must cause any work that you distribute or publish, that in
darkhan@105 99 whole or in part contains or is derived from the Program or any
darkhan@105 100 part thereof, to be licensed as a whole at no charge to all third
darkhan@105 101 parties under the terms of this License.
darkhan@105 102
darkhan@105 103 c) If the modified program normally reads commands interactively
darkhan@105 104 when run, you must cause it, when started running for such
darkhan@105 105 interactive use in the most ordinary way, to print or display an
darkhan@105 106 announcement including an appropriate copyright notice and a
darkhan@105 107 notice that there is no warranty (or else, saying that you provide
darkhan@105 108 a warranty) and that users may redistribute the program under
darkhan@105 109 these conditions, and telling the user how to view a copy of this
darkhan@105 110 License. (Exception: if the Program itself is interactive but
darkhan@105 111 does not normally print such an announcement, your work based on
darkhan@105 112 the Program is not required to print an announcement.)
darkhan@105 113
darkhan@105 114 These requirements apply to the modified work as a whole. If
darkhan@105 115 identifiable sections of that work are not derived from the Program,
darkhan@105 116 and can be reasonably considered independent and separate works in
darkhan@105 117 themselves, then this License, and its terms, do not apply to those
darkhan@105 118 sections when you distribute them as separate works. But when you
darkhan@105 119 distribute the same sections as part of a whole which is a work based
darkhan@105 120 on the Program, the distribution of the whole must be on the terms of
darkhan@105 121 this License, whose permissions for other licensees extend to the
darkhan@105 122 entire whole, and thus to each and every part regardless of who wrote it.
darkhan@105 123
darkhan@105 124 Thus, it is not the intent of this section to claim rights or contest
darkhan@105 125 your rights to work written entirely by you; rather, the intent is to
darkhan@105 126 exercise the right to control the distribution of derivative or
darkhan@105 127 collective works based on the Program.
darkhan@105 128
darkhan@105 129 In addition, mere aggregation of another work not based on the Program
darkhan@105 130 with the Program (or with a work based on the Program) on a volume of
darkhan@105 131 a storage or distribution medium does not bring the other work under
darkhan@105 132 the scope of this License.
darkhan@105 133
darkhan@105 134 3. You may copy and distribute the Program (or a work based on it,
darkhan@105 135 under Section 2) in object code or executable form under the terms of
darkhan@105 136 Sections 1 and 2 above provided that you also do one of the following:
darkhan@105 137
darkhan@105 138 a) Accompany it with the complete corresponding machine-readable
darkhan@105 139 source code, which must be distributed under the terms of Sections
darkhan@105 140 1 and 2 above on a medium customarily used for software interchange; or,
darkhan@105 141
darkhan@105 142 b) Accompany it with a written offer, valid for at least three
darkhan@105 143 years, to give any third party, for a charge no more than your
darkhan@105 144 cost of physically performing source distribution, a complete
darkhan@105 145 machine-readable copy of the corresponding source code, to be
darkhan@105 146 distributed under the terms of Sections 1 and 2 above on a medium
darkhan@105 147 customarily used for software interchange; or,
darkhan@105 148
darkhan@105 149 c) Accompany it with the information you received as to the offer
darkhan@105 150 to distribute corresponding source code. (This alternative is
darkhan@105 151 allowed only for noncommercial distribution and only if you
darkhan@105 152 received the program in object code or executable form with such
darkhan@105 153 an offer, in accord with Subsection b above.)
darkhan@105 154
darkhan@105 155 The source code for a work means the preferred form of the work for
darkhan@105 156 making modifications to it. For an executable work, complete source
darkhan@105 157 code means all the source code for all modules it contains, plus any
darkhan@105 158 associated interface definition files, plus the scripts used to
darkhan@105 159 control compilation and installation of the executable. However, as a
darkhan@105 160 special exception, the source code distributed need not include
darkhan@105 161 anything that is normally distributed (in either source or binary
darkhan@105 162 form) with the major components (compiler, kernel, and so on) of the
darkhan@105 163 operating system on which the executable runs, unless that component
darkhan@105 164 itself accompanies the executable.
darkhan@105 165
darkhan@105 166 If distribution of executable or object code is made by offering
darkhan@105 167 access to copy from a designated place, then offering equivalent
darkhan@105 168 access to copy the source code from the same place counts as
darkhan@105 169 distribution of the source code, even though third parties are not
darkhan@105 170 compelled to copy the source along with the object code.
darkhan@105 171
darkhan@105 172 4. You may not copy, modify, sublicense, or distribute the Program
darkhan@105 173 except as expressly provided under this License. Any attempt
darkhan@105 174 otherwise to copy, modify, sublicense or distribute the Program is
darkhan@105 175 void, and will automatically terminate your rights under this License.
darkhan@105 176 However, parties who have received copies, or rights, from you under
darkhan@105 177 this License will not have their licenses terminated so long as such
darkhan@105 178 parties remain in full compliance.
darkhan@105 179
darkhan@105 180 5. You are not required to accept this License, since you have not
darkhan@105 181 signed it. However, nothing else grants you permission to modify or
darkhan@105 182 distribute the Program or its derivative works. These actions are
darkhan@105 183 prohibited by law if you do not accept this License. Therefore, by
darkhan@105 184 modifying or distributing the Program (or any work based on the
darkhan@105 185 Program), you indicate your acceptance of this License to do so, and
darkhan@105 186 all its terms and conditions for copying, distributing or modifying
darkhan@105 187 the Program or works based on it.
darkhan@105 188
darkhan@105 189 6. Each time you redistribute the Program (or any work based on the
darkhan@105 190 Program), the recipient automatically receives a license from the
darkhan@105 191 original licensor to copy, distribute or modify the Program subject to
darkhan@105 192 these terms and conditions. You may not impose any further
darkhan@105 193 restrictions on the recipients' exercise of the rights granted herein.
darkhan@105 194 You are not responsible for enforcing compliance by third parties to
darkhan@105 195 this License.
darkhan@105 196
darkhan@105 197 7. If, as a consequence of a court judgment or allegation of patent
darkhan@105 198 infringement or for any other reason (not limited to patent issues),
darkhan@105 199 conditions are imposed on you (whether by court order, agreement or
darkhan@105 200 otherwise) that contradict the conditions of this License, they do not
darkhan@105 201 excuse you from the conditions of this License. If you cannot
darkhan@105 202 distribute so as to satisfy simultaneously your obligations under this
darkhan@105 203 License and any other pertinent obligations, then as a consequence you
darkhan@105 204 may not distribute the Program at all. For example, if a patent
darkhan@105 205 license would not permit royalty-free redistribution of the Program by
darkhan@105 206 all those who receive copies directly or indirectly through you, then
darkhan@105 207 the only way you could satisfy both it and this License would be to
darkhan@105 208 refrain entirely from distribution of the Program.
darkhan@105 209
darkhan@105 210 If any portion of this section is held invalid or unenforceable under
darkhan@105 211 any particular circumstance, the balance of the section is intended to
darkhan@105 212 apply and the section as a whole is intended to apply in other
darkhan@105 213 circumstances.
darkhan@105 214
darkhan@105 215 It is not the purpose of this section to induce you to infringe any
darkhan@105 216 patents or other property right claims or to contest validity of any
darkhan@105 217 such claims; this section has the sole purpose of protecting the
darkhan@105 218 integrity of the free software distribution system, which is
darkhan@105 219 implemented by public license practices. Many people have made
darkhan@105 220 generous contributions to the wide range of software distributed
darkhan@105 221 through that system in reliance on consistent application of that
darkhan@105 222 system; it is up to the author/donor to decide if he or she is willing
darkhan@105 223 to distribute software through any other system and a licensee cannot
darkhan@105 224 impose that choice.
darkhan@105 225
darkhan@105 226 This section is intended to make thoroughly clear what is believed to
darkhan@105 227 be a consequence of the rest of this License.
darkhan@105 228
darkhan@105 229 8. If the distribution and/or use of the Program is restricted in
darkhan@105 230 certain countries either by patents or by copyrighted interfaces, the
darkhan@105 231 original copyright holder who places the Program under this License
darkhan@105 232 may add an explicit geographical distribution limitation excluding
darkhan@105 233 those countries, so that distribution is permitted only in or among
darkhan@105 234 countries not thus excluded. In such case, this License incorporates
darkhan@105 235 the limitation as if written in the body of this License.
darkhan@105 236
darkhan@105 237 9. The Free Software Foundation may publish revised and/or new versions
darkhan@105 238 of the General Public License from time to time. Such new versions will
darkhan@105 239 be similar in spirit to the present version, but may differ in detail to
darkhan@105 240 address new problems or concerns.
darkhan@105 241
darkhan@105 242 Each version is given a distinguishing version number. If the Program
darkhan@105 243 specifies a version number of this License which applies to it and "any
darkhan@105 244 later version", you have the option of following the terms and conditions
darkhan@105 245 either of that version or of any later version published by the Free
darkhan@105 246 Software Foundation. If the Program does not specify a version number of
darkhan@105 247 this License, you may choose any version ever published by the Free Software
darkhan@105 248 Foundation.
darkhan@105 249
darkhan@105 250 10. If you wish to incorporate parts of the Program into other free
darkhan@105 251 programs whose distribution conditions are different, write to the author
darkhan@105 252 to ask for permission. For software which is copyrighted by the Free
darkhan@105 253 Software Foundation, write to the Free Software Foundation; we sometimes
darkhan@105 254 make exceptions for this. Our decision will be guided by the two goals
darkhan@105 255 of preserving the free status of all derivatives of our free software and
darkhan@105 256 of promoting the sharing and reuse of software generally.
darkhan@105 257
darkhan@105 258 NO WARRANTY
darkhan@105 259
darkhan@105 260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
darkhan@105 261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
darkhan@105 262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
darkhan@105 263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
darkhan@105 264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
darkhan@105 265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
darkhan@105 266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
darkhan@105 267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
darkhan@105 268 REPAIR OR CORRECTION.
darkhan@105 269
darkhan@105 270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
darkhan@105 271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
darkhan@105 272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
darkhan@105 273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
darkhan@105 274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
darkhan@105 275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
darkhan@105 276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
darkhan@105 277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
darkhan@105 278 POSSIBILITY OF SUCH DAMAGES.
darkhan@105 279
darkhan@105 280 END OF TERMS AND CONDITIONS
darkhan@105 281
darkhan@105 282 How to Apply These Terms to Your New Programs
darkhan@105 283
darkhan@105 284 If you develop a new program, and you want it to be of the greatest
darkhan@105 285 possible use to the public, the best way to achieve this is to make it
darkhan@105 286 free software which everyone can redistribute and change under these terms.
darkhan@105 287
darkhan@105 288 To do so, attach the following notices to the program. It is safest
darkhan@105 289 to attach them to the start of each source file to most effectively
darkhan@105 290 convey the exclusion of warranty; and each file should have at least
darkhan@105 291 the "copyright" line and a pointer to where the full notice is found.
darkhan@105 292
darkhan@105 293 <one line to give the program's name and a brief idea of what it does.>
darkhan@105 294 Copyright (C) <year> <name of author>
darkhan@105 295
darkhan@105 296 This program is free software; you can redistribute it and/or modify
darkhan@105 297 it under the terms of the GNU General Public License as published by
darkhan@105 298 the Free Software Foundation; either version 2 of the License, or
darkhan@105 299 (at your option) any later version.
darkhan@105 300
darkhan@105 301 This program is distributed in the hope that it will be useful,
darkhan@105 302 but WITHOUT ANY WARRANTY; without even the implied warranty of
darkhan@105 303 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
darkhan@105 304 GNU General Public License for more details.
darkhan@105 305
darkhan@105 306 You should have received a copy of the GNU General Public License along
darkhan@105 307 with this program; if not, write to the Free Software Foundation, Inc.,
darkhan@105 308 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
darkhan@105 309
darkhan@105 310 Also add information on how to contact you by electronic and paper mail.
darkhan@105 311
darkhan@105 312 If the program is interactive, make it output a short notice like this
darkhan@105 313 when it starts in an interactive mode:
darkhan@105 314
darkhan@105 315 Gnomovision version 69, Copyright (C) year name of author
darkhan@105 316 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
darkhan@105 317 This is free software, and you are welcome to redistribute it
darkhan@105 318 under certain conditions; type `show c' for details.
darkhan@105 319
darkhan@105 320 The hypothetical commands `show w' and `show c' should show the appropriate
darkhan@105 321 parts of the General Public License. Of course, the commands you use may
darkhan@105 322 be called something other than `show w' and `show c'; they could even be
darkhan@105 323 mouse-clicks or menu items--whatever suits your program.
darkhan@105 324
darkhan@105 325 You should also get your employer (if you work as a programmer) or your
darkhan@105 326 school, if any, to sign a "copyright disclaimer" for the program, if
darkhan@105 327 necessary. Here is a sample; alter the names:
darkhan@105 328
darkhan@105 329 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
darkhan@105 330 `Gnomovision' (which makes passes at compilers) written by James Hacker.

darkhan@105 333 Ty Coon, President of Vice
darkhan@105 334
darkhan@105 335 This General Public License does not permit incorporating your program into
darkhan@105 336 proprietary programs. If your program is a subroutine library, you may
darkhan@105 337 consider it more useful to permit linking proprietary applications with the
darkhan@105 338 library. If this is what you want to do, use the GNU Lesser General
darkhan@105 339 Public License instead of this License.
