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

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