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