meillo@0 1 GNU GENERAL PUBLIC LICENSE
meillo@0 2 Version 2, June 1991

meillo@0 5 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
meillo@0 6 Everyone is permitted to copy and distribute verbatim copies
meillo@0 7 of this license document, but changing it is not allowed.
meillo@0 8
meillo@0 9 Preamble
meillo@0 10
meillo@0 11 The licenses for most software are designed to take away your
meillo@0 12 freedom to share and change it. By contrast, the GNU General Public
meillo@0 13 License is intended to guarantee your freedom to share and change free
meillo@0 14 software--to make sure the software is free for all its users. This
meillo@0 15 General Public License applies to most of the Free Software
meillo@0 16 Foundation's software and to any other program whose authors commit to
meillo@0 17 using it. (Some other Free Software Foundation software is covered by
meillo@0 18 the GNU Library General Public License instead.) You can apply it to
meillo@0 19 your programs, too.
meillo@0 20
meillo@0 21 When we speak of free software, we are referring to freedom, not
meillo@0 22 price. Our General Public Licenses are designed to make sure that you
meillo@0 23 have the freedom to distribute copies of free software (and charge for
meillo@0 24 this service if you wish), that you receive source code or can get it
meillo@0 25 if you want it, that you can change the software or use pieces of it
meillo@0 26 in new free programs; and that you know you can do these things.
meillo@0 27
meillo@0 28 To protect your rights, we need to make restrictions that forbid
meillo@0 29 anyone to deny you these rights or to ask you to surrender the rights.
meillo@0 30 These restrictions translate to certain responsibilities for you if you
meillo@0 31 distribute copies of the software, or if you modify it.
meillo@0 32
meillo@0 33 For example, if you distribute copies of such a program, whether
meillo@0 34 gratis or for a fee, you must give the recipients all the rights that
meillo@0 35 you have. You must make sure that they, too, receive or can get the
meillo@0 36 source code. And you must show them these terms so they know their
meillo@0 37 rights.
meillo@0 38
meillo@0 39 We protect your rights with two steps: (1) copyright the software, and
meillo@0 40 (2) offer you this license which gives you legal permission to copy,
meillo@0 41 distribute and/or modify the software.
meillo@0 42
meillo@0 43 Also, for each author's protection and ours, we want to make certain
meillo@0 44 that everyone understands that there is no warranty for this free
meillo@0 45 software. If the software is modified by someone else and passed on, we
meillo@0 46 want its recipients to know that what they have is not the original, so
meillo@0 47 that any problems introduced by others will not reflect on the original
meillo@0 48 authors' reputations.
meillo@0 49
meillo@0 50 Finally, any free program is threatened constantly by software
meillo@0 51 patents. We wish to avoid the danger that redistributors of a free
meillo@0 52 program will individually obtain patent licenses, in effect making the
meillo@0 53 program proprietary. To prevent this, we have made it clear that any
meillo@0 54 patent must be licensed for everyone's free use or not licensed at all.
meillo@0 55
meillo@0 56 The precise terms and conditions for copying, distribution and
meillo@0 57 modification follow.
meillo@0 58
meillo@0 59 GNU GENERAL PUBLIC LICENSE
meillo@0 60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
meillo@0 61
meillo@0 62 0. This License applies to any program or other work which contains
meillo@0 63 a notice placed by the copyright holder saying it may be distributed
meillo@0 64 under the terms of this General Public License. The "Program", below,
meillo@0 65 refers to any such program or work, and a "work based on the Program"
meillo@0 66 means either the Program or any derivative work under copyright law:
meillo@0 67 that is to say, a work containing the Program or a portion of it,
meillo@0 68 either verbatim or with modifications and/or translated into another
meillo@0 69 language. (Hereinafter, translation is included without limitation in
meillo@0 70 the term "modification".) Each licensee is addressed as "you".
meillo@0 71
meillo@0 72 Activities other than copying, distribution and modification are not
meillo@0 73 covered by this License; they are outside its scope. The act of
meillo@0 74 running the Program is not restricted, and the output from the Program
meillo@0 75 is covered only if its contents constitute a work based on the
meillo@0 76 Program (independent of having been made by running the Program).
meillo@0 77 Whether that is true depends on what the Program does.
meillo@0 78
meillo@0 79 1. You may copy and distribute verbatim copies of the Program's
meillo@0 80 source code as you receive it, in any medium, provided that you
meillo@0 81 conspicuously and appropriately publish on each copy an appropriate
meillo@0 82 copyright notice and disclaimer of warranty; keep intact all the
meillo@0 83 notices that refer to this License and to the absence of any warranty;
meillo@0 84 and give any other recipients of the Program a copy of this License
meillo@0 85 along with the Program.
meillo@0 86
meillo@0 87 You may charge a fee for the physical act of transferring a copy, and
meillo@0 88 you may at your option offer warranty protection in exchange for a fee.
meillo@0 89
meillo@0 90 2. You may modify your copy or copies of the Program or any portion
meillo@0 91 of it, thus forming a work based on the Program, and copy and
meillo@0 92 distribute such modifications or work under the terms of Section 1
meillo@0 93 above, provided that you also meet all of these conditions:
meillo@0 94
meillo@0 95 a) You must cause the modified files to carry prominent notices
meillo@0 96 stating that you changed the files and the date of any change.
meillo@0 97
meillo@0 98 b) You must cause any work that you distribute or publish, that in
meillo@0 99 whole or in part contains or is derived from the Program or any
meillo@0 100 part thereof, to be licensed as a whole at no charge to all third
meillo@0 101 parties under the terms of this License.
meillo@0 102
meillo@0 103 c) If the modified program normally reads commands interactively
meillo@0 104 when run, you must cause it, when started running for such
meillo@0 105 interactive use in the most ordinary way, to print or display an
meillo@0 106 announcement including an appropriate copyright notice and a
meillo@0 107 notice that there is no warranty (or else, saying that you provide
meillo@0 108 a warranty) and that users may redistribute the program under
meillo@0 109 these conditions, and telling the user how to view a copy of this
meillo@0 110 License. (Exception: if the Program itself is interactive but
meillo@0 111 does not normally print such an announcement, your work based on
meillo@0 112 the Program is not required to print an announcement.)
meillo@0 113
meillo@0 114 These requirements apply to the modified work as a whole. If
meillo@0 115 identifiable sections of that work are not derived from the Program,
meillo@0 116 and can be reasonably considered independent and separate works in
meillo@0 117 themselves, then this License, and its terms, do not apply to those
meillo@0 118 sections when you distribute them as separate works. But when you
meillo@0 119 distribute the same sections as part of a whole which is a work based
meillo@0 120 on the Program, the distribution of the whole must be on the terms of
meillo@0 121 this License, whose permissions for other licensees extend to the
meillo@0 122 entire whole, and thus to each and every part regardless of who wrote it.
meillo@0 123
meillo@0 124 Thus, it is not the intent of this section to claim rights or contest
meillo@0 125 your rights to work written entirely by you; rather, the intent is to
meillo@0 126 exercise the right to control the distribution of derivative or
meillo@0 127 collective works based on the Program.
meillo@0 128
meillo@0 129 In addition, mere aggregation of another work not based on the Program
meillo@0 130 with the Program (or with a work based on the Program) on a volume of
meillo@0 131 a storage or distribution medium does not bring the other work under
meillo@0 132 the scope of this License.
meillo@0 133
meillo@0 134 3. You may copy and distribute the Program (or a work based on it,
meillo@0 135 under Section 2) in object code or executable form under the terms of
meillo@0 136 Sections 1 and 2 above provided that you also do one of the following:
meillo@0 137
meillo@0 138 a) Accompany it with the complete corresponding machine-readable
meillo@0 139 source code, which must be distributed under the terms of Sections
meillo@0 140 1 and 2 above on a medium customarily used for software interchange; or,
meillo@0 141
meillo@0 142 b) Accompany it with a written offer, valid for at least three
meillo@0 143 years, to give any third party, for a charge no more than your
meillo@0 144 cost of physically performing source distribution, a complete
meillo@0 145 machine-readable copy of the corresponding source code, to be
meillo@0 146 distributed under the terms of Sections 1 and 2 above on a medium
meillo@0 147 customarily used for software interchange; or,
meillo@0 148
meillo@0 149 c) Accompany it with the information you received as to the offer
meillo@0 150 to distribute corresponding source code. (This alternative is
meillo@0 151 allowed only for noncommercial distribution and only if you
meillo@0 152 received the program in object code or executable form with such
meillo@0 153 an offer, in accord with Subsection b above.)
meillo@0 154
meillo@0 155 The source code for a work means the preferred form of the work for
meillo@0 156 making modifications to it. For an executable work, complete source
meillo@0 157 code means all the source code for all modules it contains, plus any
meillo@0 158 associated interface definition files, plus the scripts used to
meillo@0 159 control compilation and installation of the executable. However, as a
meillo@0 160 special exception, the source code distributed need not include
meillo@0 161 anything that is normally distributed (in either source or binary
meillo@0 162 form) with the major components (compiler, kernel, and so on) of the
meillo@0 163 operating system on which the executable runs, unless that component
meillo@0 164 itself accompanies the executable.
meillo@0 165
meillo@0 166 If distribution of executable or object code is made by offering
meillo@0 167 access to copy from a designated place, then offering equivalent
meillo@0 168 access to copy the source code from the same place counts as
meillo@0 169 distribution of the source code, even though third parties are not
meillo@0 170 compelled to copy the source along with the object code.
meillo@0 171
meillo@0 172 4. You may not copy, modify, sublicense, or distribute the Program
meillo@0 173 except as expressly provided under this License. Any attempt
meillo@0 174 otherwise to copy, modify, sublicense or distribute the Program is
meillo@0 175 void, and will automatically terminate your rights under this License.
meillo@0 176 However, parties who have received copies, or rights, from you under
meillo@0 177 this License will not have their licenses terminated so long as such
meillo@0 178 parties remain in full compliance.
meillo@0 179
meillo@0 180 5. You are not required to accept this License, since you have not
meillo@0 181 signed it. However, nothing else grants you permission to modify or
meillo@0 182 distribute the Program or its derivative works. These actions are
meillo@0 183 prohibited by law if you do not accept this License. Therefore, by
meillo@0 184 modifying or distributing the Program (or any work based on the
meillo@0 185 Program), you indicate your acceptance of this License to do so, and
meillo@0 186 all its terms and conditions for copying, distributing or modifying
meillo@0 187 the Program or works based on it.
meillo@0 188
meillo@0 189 6. Each time you redistribute the Program (or any work based on the
meillo@0 190 Program), the recipient automatically receives a license from the
meillo@0 191 original licensor to copy, distribute or modify the Program subject to
meillo@0 192 these terms and conditions. You may not impose any further
meillo@0 193 restrictions on the recipients' exercise of the rights granted herein.
meillo@0 194 You are not responsible for enforcing compliance by third parties to
meillo@0 195 this License.
meillo@0 196
meillo@0 197 7. If, as a consequence of a court judgment or allegation of patent
meillo@0 198 infringement or for any other reason (not limited to patent issues),
meillo@0 199 conditions are imposed on you (whether by court order, agreement or
meillo@0 200 otherwise) that contradict the conditions of this License, they do not
meillo@0 201 excuse you from the conditions of this License. If you cannot
meillo@0 202 distribute so as to satisfy simultaneously your obligations under this
meillo@0 203 License and any other pertinent obligations, then as a consequence you
meillo@0 204 may not distribute the Program at all. For example, if a patent
meillo@0 205 license would not permit royalty-free redistribution of the Program by
meillo@0 206 all those who receive copies directly or indirectly through you, then
meillo@0 207 the only way you could satisfy both it and this License would be to
meillo@0 208 refrain entirely from distribution of the Program.
meillo@0 209
meillo@0 210 If any portion of this section is held invalid or unenforceable under
meillo@0 211 any particular circumstance, the balance of the section is intended to
meillo@0 212 apply and the section as a whole is intended to apply in other
meillo@0 213 circumstances.
meillo@0 214
meillo@0 215 It is not the purpose of this section to induce you to infringe any
meillo@0 216 patents or other property right claims or to contest validity of any
meillo@0 217 such claims; this section has the sole purpose of protecting the
meillo@0 218 integrity of the free software distribution system, which is
meillo@0 219 implemented by public license practices. Many people have made
meillo@0 220 generous contributions to the wide range of software distributed
meillo@0 221 through that system in reliance on consistent application of that
meillo@0 222 system; it is up to the author/donor to decide if he or she is willing
meillo@0 223 to distribute software through any other system and a licensee cannot
meillo@0 224 impose that choice.
meillo@0 225
meillo@0 226 This section is intended to make thoroughly clear what is believed to
meillo@0 227 be a consequence of the rest of this License.
meillo@0 228
meillo@0 229 8. If the distribution and/or use of the Program is restricted in
meillo@0 230 certain countries either by patents or by copyrighted interfaces, the
meillo@0 231 original copyright holder who places the Program under this License
meillo@0 232 may add an explicit geographical distribution limitation excluding
meillo@0 233 those countries, so that distribution is permitted only in or among
meillo@0 234 countries not thus excluded. In such case, this License incorporates
meillo@0 235 the limitation as if written in the body of this License.
meillo@0 236
meillo@0 237 9. The Free Software Foundation may publish revised and/or new versions
meillo@0 238 of the General Public License from time to time. Such new versions will
meillo@0 239 be similar in spirit to the present version, but may differ in detail to
meillo@0 240 address new problems or concerns.
meillo@0 241
meillo@0 242 Each version is given a distinguishing version number. If the Program
meillo@0 243 specifies a version number of this License which applies to it and "any
meillo@0 244 later version", you have the option of following the terms and conditions
meillo@0 245 either of that version or of any later version published by the Free
meillo@0 246 Software Foundation. If the Program does not specify a version number of
meillo@0 247 this License, you may choose any version ever published by the Free Software
meillo@0 248 Foundation.
meillo@0 249
meillo@0 250 10. If you wish to incorporate parts of the Program into other free
meillo@0 251 programs whose distribution conditions are different, write to the author
meillo@0 252 to ask for permission. For software which is copyrighted by the Free
meillo@0 253 Software Foundation, write to the Free Software Foundation; we sometimes
meillo@0 254 make exceptions for this. Our decision will be guided by the two goals
meillo@0 255 of preserving the free status of all derivatives of our free software and
meillo@0 256 of promoting the sharing and reuse of software generally.
meillo@0 257
meillo@0 258 NO WARRANTY
meillo@0 259
meillo@0 260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
meillo@0 261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
meillo@0 262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
meillo@0 263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
meillo@0 264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
meillo@0 265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
meillo@0 266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
meillo@0 267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
meillo@0 268 REPAIR OR CORRECTION.
meillo@0 269
meillo@0 270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
meillo@0 271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
meillo@0 272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
meillo@0 273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
meillo@0 274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
meillo@0 275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
meillo@0 276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
meillo@0 277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
meillo@0 278 POSSIBILITY OF SUCH DAMAGES.
meillo@0 279
meillo@0 280 END OF TERMS AND CONDITIONS
meillo@0 281
meillo@0 282 How to Apply These Terms to Your New Programs
meillo@0 283
meillo@0 284 If you develop a new program, and you want it to be of the greatest
meillo@0 285 possible use to the public, the best way to achieve this is to make it
meillo@0 286 free software which everyone can redistribute and change under these terms.
meillo@0 287
meillo@0 288 To do so, attach the following notices to the program. It is safest
meillo@0 289 to attach them to the start of each source file to most effectively
meillo@0 290 convey the exclusion of warranty; and each file should have at least
meillo@0 291 the "copyright" line and a pointer to where the full notice is found.
meillo@0 292
meillo@0 293 <one line to give the program's name and a brief idea of what it does.>
meillo@0 294 Copyright (C) <year> <name of author>
meillo@0 295
meillo@0 296 This program is free software; you can redistribute it and/or modify
meillo@0 297 it under the terms of the GNU General Public License as published by
meillo@0 298 the Free Software Foundation; either version 2 of the License, or
meillo@0 299 (at your option) any later version.
meillo@0 300
meillo@0 301 This program is distributed in the hope that it will be useful,
meillo@0 302 but WITHOUT ANY WARRANTY; without even the implied warranty of
meillo@0 303 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
meillo@0 304 GNU General Public License for more details.
meillo@0 305
meillo@0 306 You should have received a copy of the GNU General Public License
meillo@0 307 along with this program; if not, write to the Free Software
meillo@0 308 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
meillo@0 309
meillo@0 310
meillo@0 311 Also add information on how to contact you by electronic and paper mail.
meillo@0 312
meillo@0 313 If the program is interactive, make it output a short notice like this
meillo@0 314 when it starts in an interactive mode:
meillo@0 315
meillo@0 316 Gnomovision version 69, Copyright (C) year name of author
meillo@0 317 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
meillo@0 318 This is free software, and you are welcome to redistribute it
meillo@0 319 under certain conditions; type `show c' for details.
meillo@0 320
meillo@0 321 The hypothetical commands `show w' and `show c' should show the appropriate
meillo@0 322 parts of the General Public License. Of course, the commands you use may
meillo@0 323 be called something other than `show w' and `show c'; they could even be
meillo@0 324 mouse-clicks or menu items--whatever suits your program.
meillo@0 325
meillo@0 326 You should also get your employer (if you work as a programmer) or your
meillo@0 327 school, if any, to sign a "copyright disclaimer" for the program, if
meillo@0 328 necessary. Here is a sample; alter the names:
meillo@0 329
meillo@0 330 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
meillo@0 331 `Gnomovision' (which makes passes at compilers) written by James Hacker.

meillo@0 335
meillo@0 336 This General Public License does not permit incorporating your program into
meillo@0 337 proprietary programs. If your program is a subroutine library, you may
meillo@0 338 consider it more useful to permit linking proprietary applications with the
meillo@0 339 library. If this is what you want to do, use the GNU Library General
meillo@0 340 Public License instead of this License.
