franck@19 5 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
franck@19 6 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
webmaster@1 7 Everyone is permitted to copy and distribute verbatim copies
webmaster@1 8 of this license document, but changing it is not allowed.
webmaster@1 9
franck@19 10 Preamble
webmaster@1 11
webmaster@1 12 The licenses for most software are designed to take away your
webmaster@1 13 freedom to share and change it. By contrast, the GNU General Public
webmaster@1 14 License is intended to guarantee your freedom to share and change free
webmaster@1 15 software--to make sure the software is free for all its users. This
webmaster@1 16 General Public License applies to most of the Free Software
webmaster@1 17 Foundation's software and to any other program whose authors commit to
webmaster@1 18 using it. (Some other Free Software Foundation software is covered by
webmaster@1 19 the GNU Lesser General Public License instead.) You can apply it to
webmaster@1 20 your programs, too.
webmaster@1 21
webmaster@1 22 When we speak of free software, we are referring to freedom, not
webmaster@1 23 price. Our General Public Licenses are designed to make sure that you
webmaster@1 24 have the freedom to distribute copies of free software (and charge for
webmaster@1 25 this service if you wish), that you receive source code or can get it
webmaster@1 26 if you want it, that you can change the software or use pieces of it
webmaster@1 27 in new free programs; and that you know you can do these things.
webmaster@1 28
webmaster@1 29 To protect your rights, we need to make restrictions that forbid
webmaster@1 30 anyone to deny you these rights or to ask you to surrender the rights.
webmaster@1 31 These restrictions translate to certain responsibilities for you if you
webmaster@1 32 distribute copies of the software, or if you modify it.
webmaster@1 33
webmaster@1 34 For example, if you distribute copies of such a program, whether
webmaster@1 35 gratis or for a fee, you must give the recipients all the rights that
webmaster@1 36 you have. You must make sure that they, too, receive or can get the
webmaster@1 37 source code. And you must show them these terms so they know their
webmaster@1 38 rights.
webmaster@1 39
webmaster@1 40 We protect your rights with two steps: (1) copyright the software, and
webmaster@1 41 (2) offer you this license which gives you legal permission to copy,
webmaster@1 42 distribute and/or modify the software.
webmaster@1 43
webmaster@1 44 Also, for each author's protection and ours, we want to make certain
webmaster@1 45 that everyone understands that there is no warranty for this free
webmaster@1 46 software. If the software is modified by someone else and passed on, we
webmaster@1 47 want its recipients to know that what they have is not the original, so
webmaster@1 48 that any problems introduced by others will not reflect on the original
webmaster@1 49 authors' reputations.
webmaster@1 50
webmaster@1 51 Finally, any free program is threatened constantly by software
webmaster@1 52 patents. We wish to avoid the danger that redistributors of a free
webmaster@1 53 program will individually obtain patent licenses, in effect making the
webmaster@1 54 program proprietary. To prevent this, we have made it clear that any
webmaster@1 55 patent must be licensed for everyone's free use or not licensed at all.
webmaster@1 56
webmaster@1 57 The precise terms and conditions for copying, distribution and
webmaster@1 58 modification follow.
webmaster@1 59
franck@19 60 GNU GENERAL PUBLIC LICENSE
webmaster@1 61 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
webmaster@1 62
webmaster@1 63 0. This License applies to any program or other work which contains
webmaster@1 64 a notice placed by the copyright holder saying it may be distributed
webmaster@1 65 under the terms of this General Public License. The "Program", below,
webmaster@1 66 refers to any such program or work, and a "work based on the Program"
webmaster@1 67 means either the Program or any derivative work under copyright law:
webmaster@1 68 that is to say, a work containing the Program or a portion of it,
webmaster@1 69 either verbatim or with modifications and/or translated into another
webmaster@1 70 language. (Hereinafter, translation is included without limitation in
webmaster@1 71 the term "modification".) Each licensee is addressed as "you".
webmaster@1 72
webmaster@1 73 Activities other than copying, distribution and modification are not
webmaster@1 74 covered by this License; they are outside its scope. The act of
webmaster@1 75 running the Program is not restricted, and the output from the Program
webmaster@1 76 is covered only if its contents constitute a work based on the
webmaster@1 77 Program (independent of having been made by running the Program).
webmaster@1 78 Whether that is true depends on what the Program does.
webmaster@1 79
webmaster@1 80 1. You may copy and distribute verbatim copies of the Program's
webmaster@1 81 source code as you receive it, in any medium, provided that you
webmaster@1 82 conspicuously and appropriately publish on each copy an appropriate
webmaster@1 83 copyright notice and disclaimer of warranty; keep intact all the
webmaster@1 84 notices that refer to this License and to the absence of any warranty;
webmaster@1 85 and give any other recipients of the Program a copy of this License
webmaster@1 86 along with the Program.
webmaster@1 87
webmaster@1 88 You may charge a fee for the physical act of transferring a copy, and
webmaster@1 89 you may at your option offer warranty protection in exchange for a fee.
webmaster@1 90
webmaster@1 91 2. You may modify your copy or copies of the Program or any portion
webmaster@1 92 of it, thus forming a work based on the Program, and copy and
webmaster@1 93 distribute such modifications or work under the terms of Section 1
webmaster@1 94 above, provided that you also meet all of these conditions:
webmaster@1 95
webmaster@1 96 a) You must cause the modified files to carry prominent notices
webmaster@1 97 stating that you changed the files and the date of any change.
webmaster@1 98
webmaster@1 99 b) You must cause any work that you distribute or publish, that in
webmaster@1 100 whole or in part contains or is derived from the Program or any
webmaster@1 101 part thereof, to be licensed as a whole at no charge to all third
webmaster@1 102 parties under the terms of this License.
webmaster@1 103
webmaster@1 104 c) If the modified program normally reads commands interactively
webmaster@1 105 when run, you must cause it, when started running for such
webmaster@1 106 interactive use in the most ordinary way, to print or display an
webmaster@1 107 announcement including an appropriate copyright notice and a
webmaster@1 108 notice that there is no warranty (or else, saying that you provide
webmaster@1 109 a warranty) and that users may redistribute the program under
webmaster@1 110 these conditions, and telling the user how to view a copy of this
webmaster@1 111 License. (Exception: if the Program itself is interactive but
webmaster@1 112 does not normally print such an announcement, your work based on
webmaster@1 113 the Program is not required to print an announcement.)
webmaster@1 114
webmaster@1 115 These requirements apply to the modified work as a whole. If
webmaster@1 116 identifiable sections of that work are not derived from the Program,
webmaster@1 117 and can be reasonably considered independent and separate works in
webmaster@1 118 themselves, then this License, and its terms, do not apply to those
webmaster@1 119 sections when you distribute them as separate works. But when you
webmaster@1 120 distribute the same sections as part of a whole which is a work based
webmaster@1 121 on the Program, the distribution of the whole must be on the terms of
webmaster@1 122 this License, whose permissions for other licensees extend to the
webmaster@1 123 entire whole, and thus to each and every part regardless of who wrote it.
webmaster@1 124
webmaster@1 125 Thus, it is not the intent of this section to claim rights or contest
webmaster@1 126 your rights to work written entirely by you; rather, the intent is to
webmaster@1 127 exercise the right to control the distribution of derivative or
webmaster@1 128 collective works based on the Program.
webmaster@1 129
webmaster@1 130 In addition, mere aggregation of another work not based on the Program
webmaster@1 131 with the Program (or with a work based on the Program) on a volume of
webmaster@1 132 a storage or distribution medium does not bring the other work under
webmaster@1 133 the scope of this License.
webmaster@1 134
webmaster@1 135 3. You may copy and distribute the Program (or a work based on it,
webmaster@1 136 under Section 2) in object code or executable form under the terms of
webmaster@1 137 Sections 1 and 2 above provided that you also do one of the following:
webmaster@1 138
webmaster@1 139 a) Accompany it with the complete corresponding machine-readable
webmaster@1 140 source code, which must be distributed under the terms of Sections
webmaster@1 141 1 and 2 above on a medium customarily used for software interchange; or,
webmaster@1 142
webmaster@1 143 b) Accompany it with a written offer, valid for at least three
webmaster@1 144 years, to give any third party, for a charge no more than your
webmaster@1 145 cost of physically performing source distribution, a complete
webmaster@1 146 machine-readable copy of the corresponding source code, to be
webmaster@1 147 distributed under the terms of Sections 1 and 2 above on a medium
webmaster@1 148 customarily used for software interchange; or,
webmaster@1 149
webmaster@1 150 c) Accompany it with the information you received as to the offer
webmaster@1 151 to distribute corresponding source code. (This alternative is
webmaster@1 152 allowed only for noncommercial distribution and only if you
webmaster@1 153 received the program in object code or executable form with such
webmaster@1 154 an offer, in accord with Subsection b above.)
webmaster@1 155
webmaster@1 156 The source code for a work means the preferred form of the work for
webmaster@1 157 making modifications to it. For an executable work, complete source
webmaster@1 158 code means all the source code for all modules it contains, plus any
webmaster@1 159 associated interface definition files, plus the scripts used to
webmaster@1 160 control compilation and installation of the executable. However, as a
webmaster@1 161 special exception, the source code distributed need not include
webmaster@1 162 anything that is normally distributed (in either source or binary
webmaster@1 163 form) with the major components (compiler, kernel, and so on) of the
webmaster@1 164 operating system on which the executable runs, unless that component
webmaster@1 165 itself accompanies the executable.
webmaster@1 166
webmaster@1 167 If distribution of executable or object code is made by offering
webmaster@1 168 access to copy from a designated place, then offering equivalent
webmaster@1 169 access to copy the source code from the same place counts as
webmaster@1 170 distribution of the source code, even though third parties are not
webmaster@1 171 compelled to copy the source along with the object code.
webmaster@1 172
webmaster@1 173 4. You may not copy, modify, sublicense, or distribute the Program
webmaster@1 174 except as expressly provided under this License. Any attempt
webmaster@1 175 otherwise to copy, modify, sublicense or distribute the Program is
webmaster@1 176 void, and will automatically terminate your rights under this License.
webmaster@1 177 However, parties who have received copies, or rights, from you under
webmaster@1 178 this License will not have their licenses terminated so long as such
webmaster@1 179 parties remain in full compliance.
webmaster@1 180
webmaster@1 181 5. You are not required to accept this License, since you have not
webmaster@1 182 signed it. However, nothing else grants you permission to modify or
webmaster@1 183 distribute the Program or its derivative works. These actions are
webmaster@1 184 prohibited by law if you do not accept this License. Therefore, by
webmaster@1 185 modifying or distributing the Program (or any work based on the
webmaster@1 186 Program), you indicate your acceptance of this License to do so, and
webmaster@1 187 all its terms and conditions for copying, distributing or modifying
webmaster@1 188 the Program or works based on it.
webmaster@1 189
webmaster@1 190 6. Each time you redistribute the Program (or any work based on the
webmaster@1 191 Program), the recipient automatically receives a license from the
webmaster@1 192 original licensor to copy, distribute or modify the Program subject to
webmaster@1 193 these terms and conditions. You may not impose any further
webmaster@1 194 restrictions on the recipients' exercise of the rights granted herein.
webmaster@1 195 You are not responsible for enforcing compliance by third parties to
webmaster@1 196 this License.
webmaster@1 197
webmaster@1 198 7. If, as a consequence of a court judgment or allegation of patent
webmaster@1 199 infringement or for any other reason (not limited to patent issues),
webmaster@1 200 conditions are imposed on you (whether by court order, agreement or
webmaster@1 201 otherwise) that contradict the conditions of this License, they do not
webmaster@1 202 excuse you from the conditions of this License. If you cannot
webmaster@1 203 distribute so as to satisfy simultaneously your obligations under this
webmaster@1 204 License and any other pertinent obligations, then as a consequence you
webmaster@1 205 may not distribute the Program at all. For example, if a patent
webmaster@1 206 license would not permit royalty-free redistribution of the Program by
webmaster@1 207 all those who receive copies directly or indirectly through you, then
webmaster@1 208 the only way you could satisfy both it and this License would be to
webmaster@1 209 refrain entirely from distribution of the Program.
webmaster@1 210
webmaster@1 211 If any portion of this section is held invalid or unenforceable under
webmaster@1 212 any particular circumstance, the balance of the section is intended to
webmaster@1 213 apply and the section as a whole is intended to apply in other
webmaster@1 214 circumstances.
webmaster@1 215
webmaster@1 216 It is not the purpose of this section to induce you to infringe any
webmaster@1 217 patents or other property right claims or to contest validity of any
webmaster@1 218 such claims; this section has the sole purpose of protecting the
webmaster@1 219 integrity of the free software distribution system, which is
webmaster@1 220 implemented by public license practices. Many people have made
webmaster@1 221 generous contributions to the wide range of software distributed
webmaster@1 222 through that system in reliance on consistent application of that
webmaster@1 223 system; it is up to the author/donor to decide if he or she is willing
webmaster@1 224 to distribute software through any other system and a licensee cannot
webmaster@1 225 impose that choice.
webmaster@1 226
webmaster@1 227 This section is intended to make thoroughly clear what is believed to
webmaster@1 228 be a consequence of the rest of this License.
webmaster@1 229
webmaster@1 230 8. If the distribution and/or use of the Program is restricted in
webmaster@1 231 certain countries either by patents or by copyrighted interfaces, the
webmaster@1 232 original copyright holder who places the Program under this License
webmaster@1 233 may add an explicit geographical distribution limitation excluding
webmaster@1 234 those countries, so that distribution is permitted only in or among
webmaster@1 235 countries not thus excluded. In such case, this License incorporates
webmaster@1 236 the limitation as if written in the body of this License.
webmaster@1 237
webmaster@1 238 9. The Free Software Foundation may publish revised and/or new versions
webmaster@1 239 of the General Public License from time to time. Such new versions will
webmaster@1 240 be similar in spirit to the present version, but may differ in detail to
webmaster@1 241 address new problems or concerns.
webmaster@1 242
webmaster@1 243 Each version is given a distinguishing version number. If the Program
webmaster@1 244 specifies a version number of this License which applies to it and "any
webmaster@1 245 later version", you have the option of following the terms and conditions
webmaster@1 246 either of that version or of any later version published by the Free
webmaster@1 247 Software Foundation. If the Program does not specify a version number of
webmaster@1 248 this License, you may choose any version ever published by the Free Software
webmaster@1 249 Foundation.
webmaster@1 250
webmaster@1 251 10. If you wish to incorporate parts of the Program into other free
webmaster@1 252 programs whose distribution conditions are different, write to the author
webmaster@1 253 to ask for permission. For software which is copyrighted by the Free
webmaster@1 254 Software Foundation, write to the Free Software Foundation; we sometimes
webmaster@1 255 make exceptions for this. Our decision will be guided by the two goals
webmaster@1 256 of preserving the free status of all derivatives of our free software and
webmaster@1 257 of promoting the sharing and reuse of software generally.
webmaster@1 258
franck@19 259 NO WARRANTY
webmaster@1 260
webmaster@1 261 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
webmaster@1 262 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
webmaster@1 263 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
webmaster@1 264 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
webmaster@1 265 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
webmaster@1 266 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
webmaster@1 267 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
webmaster@1 268 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
webmaster@1 269 REPAIR OR CORRECTION.
webmaster@1 270
webmaster@1 271 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
webmaster@1 272 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
webmaster@1 273 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
webmaster@1 274 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
webmaster@1 275 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
webmaster@1 276 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
webmaster@1 277 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
webmaster@1 278 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
webmaster@1 279 POSSIBILITY OF SUCH DAMAGES.
webmaster@1 280
franck@19 281 END OF TERMS AND CONDITIONS
webmaster@1 282
franck@19 283 How to Apply These Terms to Your New Programs
webmaster@1 284
webmaster@1 285 If you develop a new program, and you want it to be of the greatest
webmaster@1 286 possible use to the public, the best way to achieve this is to make it
webmaster@1 287 free software which everyone can redistribute and change under these terms.
webmaster@1 288
webmaster@1 289 To do so, attach the following notices to the program. It is safest
webmaster@1 290 to attach them to the start of each source file to most effectively
webmaster@1 291 convey the exclusion of warranty; and each file should have at least
webmaster@1 292 the "copyright" line and a pointer to where the full notice is found.
webmaster@1 293
webmaster@1 294 <one line to give the program's name and a brief idea of what it does.>
webmaster@1 295 Copyright (C) <year> <name of author>
webmaster@1 296
webmaster@1 297 This program is free software; you can redistribute it and/or modify
webmaster@1 298 it under the terms of the GNU General Public License as published by
webmaster@1 299 the Free Software Foundation; either version 2 of the License, or
webmaster@1 300 (at your option) any later version.
webmaster@1 301
webmaster@1 302 This program is distributed in the hope that it will be useful,
webmaster@1 303 but WITHOUT ANY WARRANTY; without even the implied warranty of
webmaster@1 304 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
webmaster@1 305 GNU General Public License for more details.
webmaster@1 306
franck@19 307 You should have received a copy of the GNU General Public License along
franck@19 308 with this program; if not, write to the Free Software Foundation, Inc.,
franck@19 309 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
webmaster@1 310
webmaster@1 311 Also add information on how to contact you by electronic and paper mail.
webmaster@1 312
webmaster@1 313 If the program is interactive, make it output a short notice like this
webmaster@1 314 when it starts in an interactive mode:
webmaster@1 315
webmaster@1 316 Gnomovision version 69, Copyright (C) year name of author
webmaster@1 317 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
webmaster@1 318 This is free software, and you are welcome to redistribute it
webmaster@1 319 under certain conditions; type `show c' for details.
webmaster@1 320
webmaster@1 321 The hypothetical commands `show w' and `show c' should show the appropriate
webmaster@1 322 parts of the General Public License. Of course, the commands you use may
webmaster@1 323 be called something other than `show w' and `show c'; they could even be
webmaster@1 324 mouse-clicks or menu items--whatever suits your program.
webmaster@1 325
webmaster@1 326 You should also get your employer (if you work as a programmer) or your
webmaster@1 327 school, if any, to sign a "copyright disclaimer" for the program, if
webmaster@1 328 necessary. Here is a sample; alter the names:
webmaster@1 329
webmaster@1 330 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
webmaster@1 331 `Gnomovision' (which makes passes at compilers) written by James Hacker.

webmaster@1 335
webmaster@1 336 This General Public License does not permit incorporating your program into
webmaster@1 337 proprietary programs. If your program is a subroutine library, you may
webmaster@1 338 consider it more useful to permit linking proprietary applications with the
webmaster@1 339 library. If this is what you want to do, use the GNU Lesser General
webmaster@1 340 Public License instead of this License.
