066        + "license document, but changing it is not allowed.\n"
067        + "\n"
068        + "Preamble\n"
069        + "The licenses for most software are designed to take away your freedom to share and "
070        + "change it. By contrast, the GNU General Public License is intended to guarantee your "
071        + "freedom to share and change free software--to make sure the software is free for all "
072        + "its users. This General Public License applies to most of the Free Software "
073        + "Foundation's software and to any other program whose authors commit to using it. (Some "
074        + "other Free Software Foundation software is covered by the GNU Library General Public "
075        + "License instead.) You can apply it to your programs, too.\n"
076        + "\n"
077        + "When we speak of free software, we are referring to freedom, not price. Our General "
078        + "Public Licenses are designed to make sure that you have the freedom to distribute "
079        + "copies of free software (and charge for this service if you wish), that you receive "
080        + "source code or can get it if you want it, that you can change the software or use "
081        + "pieces of it in new free programs; and that you know you can do these things."
082        + "\n"
083        + "To protect your rights, we need to make restrictions that forbid anyone to deny you "
084        + "these rights or to ask you to surrender the rights. These restrictions translate to "
085        + "certain responsibilities for you if you distribute copies of the software, or if you "
086        + "modify it.\n"
087        + "\n"
088        + "For example, if you distribute copies of such a program, whether gratis or for a fee, "
089        + "you must give the recipients all the rights that you have. You must make sure that "
090        + "they, too, receive or can get the source code. And you must show them these terms so "
091        + "they know their rights.\n"
092        + "\n"
093        + "We protect your rights with two steps: (1) copyright the software, and (2) offer you "
094        + "this license which gives you legal permission to copy, distribute and/or modify the "
095        + "software.\n"
096        + "\n"
097        + "Also, for each author's protection and ours, we want to make certain that everyone "
098        + "understands that there is no warranty for this free software. If the software is "
099        + "modified by someone else and passed on, we want its recipients to know that what they "
100        + "have is not the original, so that any problems introduced by others will not reflect "
101        + "on the original authors' reputations.\n"
102        + "\n"
103        + "Finally, any free program is threatened constantly by software patents. We wish to "
104        + "avoid the danger that redistributors of a free program will individually obtain patent "
105        + "licenses, in effect making the program proprietary. To prevent this, we have made it "
106        + "clear that any patent must be licensed for everyone's free use or not licensed at "
107        + "all.\n"
108        + "\n"
109        + "The precise terms and conditions for copying, distribution and modification follow.\n"
110        + "\n"
111        + "GNU GENERAL PUBLIC LICENSE\n"
112        + "TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n"
113        + "\n"
114        + "0. This License applies to any program or other work which contains a notice placed by "
115        + "the copyright holder saying it may be distributed under the terms of this General "
116        + "Public License. The \"Program\", below, refers to any such program or work, and a "
117        + "\"work based on the Program\" means either the Program or any derivative work under "
118        + "copyright law: that is to say, a work containing the Program or a portion of it, "
119        + "either verbatim or with modifications and/or translated into another language. "
120        + "(Hereinafter, translation is included without limitation in the term "
121        + "\"modification\".) Each licensee is addressed as \"you\".\n"
122        + "\n"
123        + "Activities other than copying, distribution and modification are not covered by this "
124        + "License; they are outside its scope. The act of running the Program is not restricted, "
125        + "and the output from the Program is covered only if its contents constitute a work "
126        + "based on the Program (independent of having been made by running the Program). Whether "
127        + "that is true depends on what the Program does.\n"
128        + "\n"
129        + "1. You may copy and distribute verbatim copies of the Program's source code as you "
130        + "receive it, in any medium, provided that you conspicuously and appropriately publish "
131        + "on each copy an appropriate copyright notice and disclaimer of warranty; keep intact "
132        + "all the notices that refer to this License and to the absence of any warranty; and "
133        + "give any other recipients of the Program a copy of this License along with the "
134        + "Program.\n"
135        + "\n"
136        + "You may charge a fee for the physical act of transferring a copy, and you may at your "
137        + "option offer warranty protection in exchange for a fee.\n"
138        + "\n"
139        + "2. You may modify your copy or copies of the Program or any portion of it, thus "
140        + "forming a work based on the Program, and copy and distribute such modifications or "
141        + "work under the terms of Section 1 above, provided that you also meet all of these "
142        + "conditions:\n"
143        + "\n"
144        + "a) You must cause the modified files to carry prominent notices stating that you "
145        + "changed the files and the date of any change.\n"
146        + "\n"
147        + "b) You must cause any work that you distribute or publish, that in whole or in part "
148        + "contains or is derived from the Program or any part thereof, to be licensed as a whole "
149        + "at no charge to all third parties under the terms of this License.\n"
150        + "\n"
151        + "c) If the modified program normally reads commands interactively when run, you must "
152        + "cause it, when started running for such interactive use in the most ordinary way, to "
153        + "print or display an announcement including an appropriate copyright notice and a "
154        + "notice that there is no warranty (or else, saying that you provide a warranty) and "
155        + "that users may redistribute the program under these conditions, and telling the user "
156        + "how to view a copy of this License. (Exception: if the Program itself is interactive "
157        + "but does not normally print such an announcement, your work based on the Program is "
158        + "not required to print an announcement.)\n"
159        + "\n"
160        + "These requirements apply to the modified work as a whole. If identifiable sections of "
161        + "that work are not derived from the Program, and can be reasonably considered "
162        + "independent and separate works in themselves, then this License, and its terms, do not "
163        + "apply to those sections when you distribute them as separate works. But when you "
164        + "distribute the same sections as part of a whole which is a work based on the Program, "
165        + "the distribution of the whole must be on the terms of this License, whose permissions "
166        + "for other licensees extend to the entire whole, and thus to each and every part "
167        + "regardless of who wrote it.\n"
168        + "\n"
169        + "Thus, it is not the intent of this section to claim rights or contest your rights to "
170        + "work written entirely by you; rather, the intent is to exercise the right to control "
171        + "the distribution of derivative or collective works based on the Program.\n"
172        + "\n"
173        + "In addition, mere aggregation of another work not based on the Program with the "
174        + "Program (or with a work based on the Program) on a volume of a storage or distribution "
175        + "medium does not bring the other work under the scope of this License.\n"
176        + "\n"
177        + "3. You may copy and distribute the Program (or a work based on it, under Section 2) in "
178        + "object code or executable form under the terms of Sections 1 and 2 above provided that "
179        + "you also do one of the following:\n"
180        + "\n"
181        + "a) Accompany it with the complete corresponding machine-readable source code, which "
182        + "must be distributed under the terms of Sections 1 and 2 above on a medium customarily "
183        + "used for software interchange; or,\n"
184        + "b) Accompany it with a written offer, valid for at least three years, to give any "
185        + "third party, for a charge no more than your cost of physically performing source "
186        + "distribution, a complete machine-readable copy of the corresponding source code, to be "
187        + "distributed under the terms of Sections 1 and 2 above on a medium customarily used for "
188        + "software interchange; or,\n"
189        + "c) Accompany it with the information you received as to the offer to distribute "
190        + "corresponding source code. (This alternative is allowed only for noncommercial "
191        + "distribution and only if you received the program in object code or executable form "
192        + "with such an offer, in accord with Subsection b above.)\n"
193        + "\n"
194        + "The source code for a work means the preferred form of the work for making "
195        + "modifications to it. For an executable work, complete source code means all the source "
196        + "code for all modules it contains, plus any associated interface definition files, plus "
197        + "the scripts used to control compilation and installation of the executable. However, "
198        + "as a special exception, the source code distributed need not include anything that is "
199        + "normally distributed (in either source or binary form) with the major components "
200        + "(compiler, kernel, and so on) of the operating system on which the executable runs, "
201        + "unless that component itself accompanies the executable.\n"
202        + "\n"
203        + "If distribution of executable or object code is made by offering access to copy from a "
204        + "designated place, then offering equivalent access to copy the source code from the "
205        + "same place counts as distribution of the source code, even though third parties are "
206        + "not compelled to copy the source along with the object code.\n"
207        + "\n"
208        + "4. You may not copy, modify, sublicense, or distribute the Program except as expressly "
209        + "provided under this License. Any attempt otherwise to copy, modify, sublicense or "
210        + "distribute the Program is void, and will automatically terminate your rights under "
211        + "this License. However, parties who have received copies, or rights, from you under "
212        + "this License will not have their licenses terminated so long as such parties remain in "
213        + "full compliance."
214        + "\n"
215        + "5. You are not required to accept this License, since you have not signed it. However, "
216        + "nothing else grants you permission to modify or distribute the Program or its "
217        + "derivative works. These actions are prohibited by law if you do not accept this "
218        + "License. Therefore, by modifying or distributing the Program (or any work based on the "
219        + "Program), you indicate your acceptance of this License to do so, and all its terms and "
220        + "conditions for copying, distributing or modifying the Program or works based on it.\n"
221        + "\n"
222        + "6. Each time you redistribute the Program (or any work based on the Program), the "
223        + "recipient automatically receives a license from the original licensor to copy, "
224        + "distribute or modify the Program subject to these terms and conditions. You may not "
225        + "impose any further restrictions on the recipients' exercise of the rights granted "
226        + "herein. You are not responsible for enforcing compliance by third parties to this "
227        + "License."
228        + "\n"
229        + "7. If, as a consequence of a court judgment or allegation of patent infringement or "
230        + "for any other reason (not limited to patent issues), conditions are imposed on you "
231        + "(whether by court order, agreement or otherwise) that contradict the conditions of "
232        + "this License, they do not excuse you from the conditions of this License. If you "
233        + "cannot distribute so as to satisfy simultaneously your obligations under this License "
234        + "and any other pertinent obligations, then as a consequence you may not distribute the "
235        + "Program at all. For example, if a patent license would not permit royalty-free "
236        + "redistribution of the Program by all those who receive copies directly or indirectly "
237        + "through you, then the only way you could satisfy both it and this License would be to "
238        + "refrain entirely from distribution of the Program.\n"
239        + "\n"
240        + "If any portion of this section is held invalid or unenforceable under any particular "
241        + "circumstance, the balance of the section is intended to apply and the section as a "
242        + "whole is intended to apply in other circumstances.\n"
243        + "\n"
244        + "It is not the purpose of this section to induce you to infringe any patents or other "
245        + "property right claims or to contest validity of any such claims; this section has the "
246        + "sole purpose of protecting the integrity of the free software distribution system, "
247        + "which is implemented by public license practices. Many people have made generous "
248        + "contributions to the wide range of software distributed through that system in "
249        + "reliance on consistent application of that system; it is up to the author/donor to "
250        + "decide if he or she is willing to distribute software through any other system and a "
251        + "licensee cannot impose that choice.\n"
252        + "\n"
253        + "This section is intended to make thoroughly clear what is believed to be a consequence "
254        + "of the rest of this License.\n"
255        + "\n"
256        + "8. If the distribution and/or use of the Program is restricted in certain countries "
257        + "either by patents or by copyrighted interfaces, the original copyright holder who "
258        + "places the Program under this License may add an explicit geographical distribution "
259        + "limitation excluding those countries, so that distribution is permitted only in or "
260        + "among countries not thus excluded. In such case, this License incorporates the "
261        + "limitation as if written in the body of this License.\n"
262        + "\n"
263        + "9. The Free Software Foundation may publish revised and/or new versions of the General "
264        + "Public License from time to time. Such new versions will be similar in spirit to the "
265        + "present version, but may differ in detail to address new problems or concerns.\n"
266        + "\n"
267        + "Each version is given a distinguishing version number. If the Program specifies a "
268        + "version number of this License which applies to it and \"any later version\", you have "
269        + "the option of following the terms and conditions either of that version or of any "
270        + "later version published by the Free Software Foundation. If the Program does not "
271        + "specify a version number of this License, you may choose any version ever published by "
272        + "the Free Software Foundation.\n"
273        + "\n"
274        + "10. If you wish to incorporate parts of the Program into other free programs whose "
275        + "distribution conditions are different, write to the author to ask for permission. For "
276        + "software which is copyrighted by the Free Software Foundation, write to the Free "
277        + "Software Foundation; we sometimes make exceptions for this. Our decision will be "
278        + "guided by the two goals of preserving the free status of all derivatives of our free "
279        + "software and of promoting the sharing and reuse of software generally.\n"
280        + "\n"
281        + "NO WARRANTY\n"
282        + "\n"
283        + "11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE "

385        + "carefully about whether this license or the ordinary General Public License is the "
386        + "better strategy to use in any particular case, based on the explanations below.\n"
387        + "\n"
388        + "When we speak of free software, we are referring to freedom of use, not price. Our "

395        + "To protect your rights, we need to make restrictions that forbid distributors to deny "

400        + "For example, if you distribute copies of the library, whether gratis or for a fee, you "

405        + "And you must show them these terms so they know their rights.\n"
406        + "\n"
407        + "We protect your rights with a two-step method: (1) we copyright the library, and (2) "

411        + "To protect each distributor, we want to make it very clear that there is no warranty "

418        + "We wish to make sure that a company cannot effectively restrict the users of a free "

423        + "Most GNU software, including some libraries, is covered by the ordinary GNU General "

425        + "certain designated libraries, and is quite different from the ordinary General Public "

428        + "\n"
429        + "When a program is linked with a library, whether statically or using a shared library, "
430        + "the combination of the two is legally speaking a combined work, a derivative of the "
431        + "original library. The ordinary General Public License therefore permits such linking "
432        + "only if the entire combination fits its criteria of freedom. The Lesser General Public "
433        + "License permits more lax criteria for linking other code with the library.\n"
434        + "\n"
435        + "We call this license the \"Lesser\" General Public License because it does Less to "
436        + "protect the user's freedom than the ordinary General Public License. It also provides "
437        + "other free software developers Less of an advantage over competing non-free programs. "
438        + "These disadvantages are the reason we use the ordinary General Public License for many "
439        + "libraries. However, the Lesser license provides advantages in certain special "
440        + "circumstances.\n"
441        + "\n"
442        + "For example, on rare occasions, there may be a special need to encourage the widest "
443        + "possible use of a certain library, so that it becomes a de-facto standard. To achieve "
444        + "this, non-free programs must be allowed to use the library. A more frequent case is "
445        + "that a free library does the same job as widely used non-free libraries. In this case, "
446        + "there is little to gain by limiting the free library to free software only, so we use "
447        + "the Lesser General Public License.\n"
448        + "\n"
449        + "In other cases, permission to use a particular library in non-free programs enables a "
450        + "greater number of people to use a large body of free software. For example, permission "
451        + "to use the GNU C Library in non-free programs enables many more people to use the "
452        + "whole GNU operating system, as well as its variant, the GNU/Linux operating system.\n"
453        + "\n"
454        + "Although the Lesser General Public License is Less protective of the users' freedom, "
455        + "it does ensure that the user of a program that is linked with the Library has the "
456        + "freedom and the wherewithal to run that program using a modified version of the "
457        + "Library.\n"
458        + "\n"
459        + "The precise terms and conditions for copying, distribution and modification follow. "
460        + "Pay close attention to the difference between a \"work based on the library\" and a "
461        + "\"work that uses the library\". The former contains code derived from the library, "

487        + "Activities other than copying, distribution and modification are not covered by this "

513        + "*    d) If a facility in the modified Library refers to a function or a table of data "
514        + "to be supplied by an application program that uses the facility, other than as an "
515        + "argument passed when the facility is invoked, then you must make a good faith effort "

519        + "\n"
520        + "(For example, a function in a library to compute square roots has a purpose that is "

526        + "These requirements apply to the modified work as a whole. If identifiable sections of "

569        + "5. A program that contains no derivative of any portion of the Library, but is "

573        + "\n"
574        + "However, linking a \"work that uses the Library\" with the Library creates an "
575        + "executable that is a derivative of the Library (because it contains portions of the "

606        + "directing the user to the copy of this License. Also, you must do one of these "

609        + "*    a) Accompany the work with the complete corresponding machine-readable source "
610        + "code for the Library including whatever changes were used in the work (which must be "
611        + "distributed under Sections 1 and 2 above); and, if the work is an executable linked "
612        + "with the Library, with the complete machine-readable \"work that uses the Library\", "
613        + "as object code and/or source code, so that the user can modify the Library and then "
614        + "relink to produce a modified executable containing the modified Library. (It is "
615        + "understood that the user who changes the contents of definitions files in the Library "
616        + "will not necessarily be able to recompile the application to use the modified "
617        + "definitions.)\n"
618        + "*    b) Use a suitable shared library mechanism for linking with the Library. A "
619        + "suitable mechanism is one that (1) uses at run time a copy of the library already "
620        + "present on the user's computer system, rather than copying library functions into the "
621        + "executable, and (2) will operate properly with a modified version of the library, if "
622        + "the user installs one, as long as the modified version is interface-compatible with "
623        + "the version that the work was made with.\n"
624        + "*    c) Accompany the work with a written offer, valid for at least three years, to "
625        + "give the same user the materials specified in Subsection 6a, above, for a charge no "
626        + "more than the cost of performing this distribution.\n"
627        + "*    d) If distribution of the work is made by offering access to copy from a "
628        + "designated place, offer equivalent access to copy the above specified materials from "
629        + "the same place.\n"
630        + "*    e) Verify that the user has already received a copy of these materials or that "
631        + "you have already sent this user a copy.\n"
632        + "\n"
633        + "For an executable, the required form of the \"work that uses the Library\" must "
634        + "include any data and utility programs needed for reproducing the executable from it. "
635        + "However, as a special exception, the materials to be distributed need not include "
636        + "anything that is normally distributed (in either source or binary form) with the major "
637        + "components (compiler, kernel, and so on) of the operating system on which the "
638        + "executable runs, unless that component itself accompanies the executable.\n"
639        + "\n"
640        + "It may happen that this requirement contradicts the license restrictions of other "
641        + "proprietary libraries that do not normally accompany the operating system. Such a "
642        + "contradiction means you cannot use both them and the Library together in an executable "
643        + "that you distribute.\n"
644        + "\n"

648        + "distribution of the work based on the Library and of the other library facilities is "
649        + "otherwise permitted, and provided that you do these two things:\n"
650        + "\n"
651        + "*    a) Accompany the combined library with a copy of the same work based on the "
652        + "Library, uncombined with any other library facilities. This must be distributed under "
653        + "the terms of the Sections above.\n"
