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