Chris@647 1 GNU GENERAL PUBLIC LICENSE
Chris@647 2 Version 2, June 1991
Chris@647 3
Chris@647 4 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
Chris@647 5 675 Mass Ave, Cambridge, MA 02139, USA
Chris@647 6 Everyone is permitted to copy and distribute verbatim copies
Chris@647 7 of this license document, but changing it is not allowed.
Chris@647 8
Chris@647 9 Preamble
Chris@647 10
Chris@647 11 The licenses for most software are designed to take away your
Chris@647 12 freedom to share and change it. By contrast, the GNU General Public
Chris@647 13 License is intended to guarantee your freedom to share and change free
Chris@647 14 software--to make sure the software is free for all its users. This
Chris@647 15 General Public License applies to most of the Free Software
Chris@647 16 Foundation's software and to any other program whose authors commit to
Chris@647 17 using it. (Some other Free Software Foundation software is covered by
Chris@647 18 the GNU Library General Public License instead.) You can apply it to
Chris@647 19 your programs, too.
Chris@647 20
Chris@647 21 When we speak of free software, we are referring to freedom, not
Chris@647 22 price. Our General Public Licenses are designed to make sure that you
Chris@647 23 have the freedom to distribute copies of free software (and charge for
Chris@647 24 this service if you wish), that you receive source code or can get it
Chris@647 25 if you want it, that you can change the software or use pieces of it
Chris@647 26 in new free programs; and that you know you can do these things.
Chris@647 27
Chris@647 28 To protect your rights, we need to make restrictions that forbid
Chris@647 29 anyone to deny you these rights or to ask you to surrender the rights.
Chris@647 30 These restrictions translate to certain responsibilities for you if you
Chris@647 31 distribute copies of the software, or if you modify it.
Chris@647 32
Chris@647 33 For example, if you distribute copies of such a program, whether
Chris@647 34 gratis or for a fee, you must give the recipients all the rights that
Chris@647 35 you have. You must make sure that they, too, receive or can get the
Chris@647 36 source code. And you must show them these terms so they know their
Chris@647 37 rights.
Chris@647 38
Chris@647 39 We protect your rights with two steps: (1) copyright the software, and
Chris@647 40 (2) offer you this license which gives you legal permission to copy,
Chris@647 41 distribute and/or modify the software.
Chris@647 42
Chris@647 43 Also, for each author's protection and ours, we want to make certain
Chris@647 44 that everyone understands that there is no warranty for this free
Chris@647 45 software. If the software is modified by someone else and passed on, we
Chris@647 46 want its recipients to know that what they have is not the original, so
Chris@647 47 that any problems introduced by others will not reflect on the original
Chris@647 48 authors' reputations.
Chris@647 49
Chris@647 50 Finally, any free program is threatened constantly by software
Chris@647 51 patents. We wish to avoid the danger that redistributors of a free
Chris@647 52 program will individually obtain patent licenses, in effect making the
Chris@647 53 program proprietary. To prevent this, we have made it clear that any
Chris@647 54 patent must be licensed for everyone's free use or not licensed at all.
Chris@647 55
Chris@647 56 The precise terms and conditions for copying, distribution and
Chris@647 57 modification follow.
Chris@647 58
Chris@647 59 GNU GENERAL PUBLIC LICENSE
Chris@647 60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
Chris@647 61
Chris@647 62 0. This License applies to any program or other work which contains
Chris@647 63 a notice placed by the copyright holder saying it may be distributed
Chris@647 64 under the terms of this General Public License. The "Program", below,
Chris@647 65 refers to any such program or work, and a "work based on the Program"
Chris@647 66 means either the Program or any derivative work under copyright law:
Chris@647 67 that is to say, a work containing the Program or a portion of it,
Chris@647 68 either verbatim or with modifications and/or translated into another
Chris@647 69 language. (Hereinafter, translation is included without limitation in
Chris@647 70 the term "modification".) Each licensee is addressed as "you".
Chris@647 71
Chris@647 72 Activities other than copying, distribution and modification are not
Chris@647 73 covered by this License; they are outside its scope. The act of
Chris@647 74 running the Program is not restricted, and the output from the Program
Chris@647 75 is covered only if its contents constitute a work based on the
Chris@647 76 Program (independent of having been made by running the Program).
Chris@647 77 Whether that is true depends on what the Program does.
Chris@647 78
Chris@647 79 1. You may copy and distribute verbatim copies of the Program's
Chris@647 80 source code as you receive it, in any medium, provided that you
Chris@647 81 conspicuously and appropriately publish on each copy an appropriate
Chris@647 82 copyright notice and disclaimer of warranty; keep intact all the
Chris@647 83 notices that refer to this License and to the absence of any warranty;
Chris@647 84 and give any other recipients of the Program a copy of this License
Chris@647 85 along with the Program.
Chris@647 86
Chris@647 87 You may charge a fee for the physical act of transferring a copy, and
Chris@647 88 you may at your option offer warranty protection in exchange for a fee.
Chris@647 89
Chris@647 90 2. You may modify your copy or copies of the Program or any portion
Chris@647 91 of it, thus forming a work based on the Program, and copy and
Chris@647 92 distribute such modifications or work under the terms of Section 1
Chris@647 93 above, provided that you also meet all of these conditions:
Chris@647 94
Chris@647 95 a) You must cause the modified files to carry prominent notices
Chris@647 96 stating that you changed the files and the date of any change.
Chris@647 97
Chris@647 98 b) You must cause any work that you distribute or publish, that in
Chris@647 99 whole or in part contains or is derived from the Program or any
Chris@647 100 part thereof, to be licensed as a whole at no charge to all third
Chris@647 101 parties under the terms of this License.
Chris@647 102
Chris@647 103 c) If the modified program normally reads commands interactively
Chris@647 104 when run, you must cause it, when started running for such
Chris@647 105 interactive use in the most ordinary way, to print or display an
Chris@647 106 announcement including an appropriate copyright notice and a
Chris@647 107 notice that there is no warranty (or else, saying that you provide
Chris@647 108 a warranty) and that users may redistribute the program under
Chris@647 109 these conditions, and telling the user how to view a copy of this
Chris@647 110 License. (Exception: if the Program itself is interactive but
Chris@647 111 does not normally print such an announcement, your work based on
Chris@647 112 the Program is not required to print an announcement.)
Chris@647 113
Chris@647 114 These requirements apply to the modified work as a whole. If
Chris@647 115 identifiable sections of that work are not derived from the Program,
Chris@647 116 and can be reasonably considered independent and separate works in
Chris@647 117 themselves, then this License, and its terms, do not apply to those
Chris@647 118 sections when you distribute them as separate works. But when you
Chris@647 119 distribute the same sections as part of a whole which is a work based
Chris@647 120 on the Program, the distribution of the whole must be on the terms of
Chris@647 121 this License, whose permissions for other licensees extend to the
Chris@647 122 entire whole, and thus to each and every part regardless of who wrote it.
Chris@647 123
Chris@647 124 Thus, it is not the intent of this section to claim rights or contest
Chris@647 125 your rights to work written entirely by you; rather, the intent is to
Chris@647 126 exercise the right to control the distribution of derivative or
Chris@647 127 collective works based on the Program.
Chris@647 128
Chris@647 129 In addition, mere aggregation of another work not based on the Program
Chris@647 130 with the Program (or with a work based on the Program) on a volume of
Chris@647 131 a storage or distribution medium does not bring the other work under
Chris@647 132 the scope of this License.
Chris@647 133
Chris@647 134 3. You may copy and distribute the Program (or a work based on it,
Chris@647 135 under Section 2) in object code or executable form under the terms of
Chris@647 136 Sections 1 and 2 above provided that you also do one of the following:
Chris@647 137
Chris@647 138 a) Accompany it with the complete corresponding machine-readable
Chris@647 139 source code, which must be distributed under the terms of Sections
Chris@647 140 1 and 2 above on a medium customarily used for software interchange; or,
Chris@647 141
Chris@647 142 b) Accompany it with a written offer, valid for at least three
Chris@647 143 years, to give any third party, for a charge no more than your
Chris@647 144 cost of physically performing source distribution, a complete
Chris@647 145 machine-readable copy of the corresponding source code, to be
Chris@647 146 distributed under the terms of Sections 1 and 2 above on a medium
Chris@647 147 customarily used for software interchange; or,
Chris@647 148
Chris@647 149 c) Accompany it with the information you received as to the offer
Chris@647 150 to distribute corresponding source code. (This alternative is
Chris@647 151 allowed only for noncommercial distribution and only if you
Chris@647 152 received the program in object code or executable form with such
Chris@647 153 an offer, in accord with Subsection b above.)
Chris@647 154
Chris@647 155 The source code for a work means the preferred form of the work for
Chris@647 156 making modifications to it. For an executable work, complete source
Chris@647 157 code means all the source code for all modules it contains, plus any
Chris@647 158 associated interface definition files, plus the scripts used to
Chris@647 159 control compilation and installation of the executable. However, as a
Chris@647 160 special exception, the source code distributed need not include
Chris@647 161 anything that is normally distributed (in either source or binary
Chris@647 162 form) with the major components (compiler, kernel, and so on) of the
Chris@647 163 operating system on which the executable runs, unless that component
Chris@647 164 itself accompanies the executable.
Chris@647 165
Chris@647 166 If distribution of executable or object code is made by offering
Chris@647 167 access to copy from a designated place, then offering equivalent
Chris@647 168 access to copy the source code from the same place counts as
Chris@647 169 distribution of the source code, even though third parties are not
Chris@647 170 compelled to copy the source along with the object code.
Chris@647 171
Chris@647 172 4. You may not copy, modify, sublicense, or distribute the Program
Chris@647 173 except as expressly provided under this License. Any attempt
Chris@647 174 otherwise to copy, modify, sublicense or distribute the Program is
Chris@647 175 void, and will automatically terminate your rights under this License.
Chris@647 176 However, parties who have received copies, or rights, from you under
Chris@647 177 this License will not have their licenses terminated so long as such
Chris@647 178 parties remain in full compliance.
Chris@647 179
Chris@647 180 5. You are not required to accept this License, since you have not
Chris@647 181 signed it. However, nothing else grants you permission to modify or
Chris@647 182 distribute the Program or its derivative works. These actions are
Chris@647 183 prohibited by law if you do not accept this License. Therefore, by
Chris@647 184 modifying or distributing the Program (or any work based on the
Chris@647 185 Program), you indicate your acceptance of this License to do so, and
Chris@647 186 all its terms and conditions for copying, distributing or modifying
Chris@647 187 the Program or works based on it.
Chris@647 188
Chris@647 189 6. Each time you redistribute the Program (or any work based on the
Chris@647 190 Program), the recipient automatically receives a license from the
Chris@647 191 original licensor to copy, distribute or modify the Program subject to
Chris@647 192 these terms and conditions. You may not impose any further
Chris@647 193 restrictions on the recipients' exercise of the rights granted herein.
Chris@647 194 You are not responsible for enforcing compliance by third parties to
Chris@647 195 this License.
Chris@647 196
Chris@647 197 7. If, as a consequence of a court judgment or allegation of patent
Chris@647 198 infringement or for any other reason (not limited to patent issues),
Chris@647 199 conditions are imposed on you (whether by court order, agreement or
Chris@647 200 otherwise) that contradict the conditions of this License, they do not
Chris@647 201 excuse you from the conditions of this License. If you cannot
Chris@647 202 distribute so as to satisfy simultaneously your obligations under this
Chris@647 203 License and any other pertinent obligations, then as a consequence you
Chris@647 204 may not distribute the Program at all. For example, if a patent
Chris@647 205 license would not permit royalty-free redistribution of the Program by
Chris@647 206 all those who receive copies directly or indirectly through you, then
Chris@647 207 the only way you could satisfy both it and this License would be to
Chris@647 208 refrain entirely from distribution of the Program.
Chris@647 209
Chris@647 210 If any portion of this section is held invalid or unenforceable under
Chris@647 211 any particular circumstance, the balance of the section is intended to
Chris@647 212 apply and the section as a whole is intended to apply in other
Chris@647 213 circumstances.
Chris@647 214
Chris@647 215 It is not the purpose of this section to induce you to infringe any
Chris@647 216 patents or other property right claims or to contest validity of any
Chris@647 217 such claims; this section has the sole purpose of protecting the
Chris@647 218 integrity of the free software distribution system, which is
Chris@647 219 implemented by public license practices. Many people have made
Chris@647 220 generous contributions to the wide range of software distributed
Chris@647 221 through that system in reliance on consistent application of that
Chris@647 222 system; it is up to the author/donor to decide if he or she is willing
Chris@647 223 to distribute software through any other system and a licensee cannot
Chris@647 224 impose that choice.
Chris@647 225
Chris@647 226 This section is intended to make thoroughly clear what is believed to
Chris@647 227 be a consequence of the rest of this License.
Chris@647 228
Chris@647 229 8. If the distribution and/or use of the Program is restricted in
Chris@647 230 certain countries either by patents or by copyrighted interfaces, the
Chris@647 231 original copyright holder who places the Program under this License
Chris@647 232 may add an explicit geographical distribution limitation excluding
Chris@647 233 those countries, so that distribution is permitted only in or among
Chris@647 234 countries not thus excluded. In such case, this License incorporates
Chris@647 235 the limitation as if written in the body of this License.
Chris@647 236
Chris@647 237 9. The Free Software Foundation may publish revised and/or new versions
Chris@647 238 of the General Public License from time to time. Such new versions will
Chris@647 239 be similar in spirit to the present version, but may differ in detail to
Chris@647 240 address new problems or concerns.
Chris@647 241
Chris@647 242 Each version is given a distinguishing version number. If the Program
Chris@647 243 specifies a version number of this License which applies to it and "any
Chris@647 244 later version", you have the option of following the terms and conditions
Chris@647 245 either of that version or of any later version published by the Free
Chris@647 246 Software Foundation. If the Program does not specify a version number of
Chris@647 247 this License, you may choose any version ever published by the Free Software
Chris@647 248 Foundation.
Chris@647 249
Chris@647 250 10. If you wish to incorporate parts of the Program into other free
Chris@647 251 programs whose distribution conditions are different, write to the author
Chris@647 252 to ask for permission. For software which is copyrighted by the Free
Chris@647 253 Software Foundation, write to the Free Software Foundation; we sometimes
Chris@647 254 make exceptions for this. Our decision will be guided by the two goals
Chris@647 255 of preserving the free status of all derivatives of our free software and
Chris@647 256 of promoting the sharing and reuse of software generally.
Chris@647 257
Chris@647 258 NO WARRANTY
Chris@647 259
Chris@647 260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
Chris@647 261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
Chris@647 262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
Chris@647 263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
Chris@647 264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
Chris@647 265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
Chris@647 266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
Chris@647 267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
Chris@647 268 REPAIR OR CORRECTION.
Chris@647 269
Chris@647 270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
Chris@647 271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
Chris@647 272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
Chris@647 273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
Chris@647 274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
Chris@647 275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
Chris@647 276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
Chris@647 277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
Chris@647 278 POSSIBILITY OF SUCH DAMAGES.
Chris@647 279
Chris@647 280 END OF TERMS AND CONDITIONS
