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

EmFor@6 334 Ty Coon, President of Vice
EmFor@6 335
EmFor@6 336 This General Public License does not permit incorporating your program into
EmFor@6 337 proprietary programs. If your program is a subroutine library, you may
EmFor@6 338 consider it more useful to permit linking proprietary applications with the
EmFor@6 339 library. If this is what you want to do, use the GNU Library General
EmFor@6 340 Public License instead of this License.
