16: GNU GENERAL PUBLIC LICENSE
17: Version 2, June 1991
18:
19: Copyright (C) 1989, 1991 Free Software Foundation, Inc.
20: 51 Franklin St, Fifth Floor, Boston, MA, 02110-1301 USA
21: Everyone is permitted to copy and distribute verbatim copies
22: of this license document, but changing it is not allowed.
23:
24: Preamble
25:
26: The licenses for most software are designed to take away your
27: freedom to share and change it. By contrast, the GNU General Public
28: License is intended to guarantee your freedom to share and change free
29: software--to make sure the software is free for all its users. This
30: General Public License applies to most of the Free Software
31: Foundation's software and to any other program whose authors commit to
32: using it. (Some other Free Software Foundation software is covered by
33: the GNU Library General Public License instead.) You can apply it to
34: your programs, too.
35:
36: When we speak of free software, we are referring to freedom, not
37: price. Our General Public Licenses are designed to make sure that you
38: have the freedom to distribute copies of free software (and charge for
39: this service if you wish), that you receive source code or can get it
40: if you want it, that you can change the software or use pieces of it
41: in new free programs; and that you know you can do these things.
42:
43: To protect your rights, we need to make restrictions that forbid
44: anyone to deny you these rights or to ask you to surrender the rights.
45: These restrictions translate to certain responsibilities for you if you
46: distribute copies of the software, or if you modify it.
47:
48: For example, if you distribute copies of such a program, whether
49: gratis or for a fee, you must give the recipients all the rights that
50: you have. You must make sure that they, too, receive or can get the
51: source code. And you must show them these terms so they know their
52: rights.
53:
54: We protect your rights with two steps: (1) copyright the software, and
55: (2) offer you this license which gives you legal permission to copy,
56: distribute and/or modify the software.
57:
58: Also, for each author's protection and ours, we want to make certain
59: that everyone understands that there is no warranty for this free
60: software. If the software is modified by someone else and passed on, we
61: want its recipients to know that what they have is not the original, so
62: that any problems introduced by others will not reflect on the original
63: authors' reputations.
64:
65: Finally, any free program is threatened constantly by software
66: patents. We wish to avoid the danger that redistributors of a free
67: program will individually obtain patent licenses, in effect making the
68: program proprietary. To prevent this, we have made it clear that any
69: patent must be licensed for everyone's free use or not licensed at all.
70:
71: The precise terms and conditions for copying, distribution and
72: modification follow.
73:
74: GNU GENERAL PUBLIC LICENSE
75: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
76:
77: 0. This License applies to any program or other work which contains
78: a notice placed by the copyright holder saying it may be distributed
79: under the terms of this General Public License. The "Program", below,
80: refers to any such program or work, and a "work based on the Program"
81: means either the Program or any derivative work under copyright law:
82: that is to say, a work containing the Program or a portion of it,
83: either verbatim or with modifications and/or translated into another
84: language. (Hereinafter, translation is included without limitation in
85: the term "modification".) Each licensee is addressed as "you".
86:
87: Activities other than copying, distribution and modification are not
88: covered by this License; they are outside its scope. The act of
89: running the Program is not restricted, and the output from the Program
90: is covered only if its contents constitute a work based on the
91: Program (independent of having been made by running the Program).
92: Whether that is true depends on what the Program does.
93:
94: 1. You may copy and distribute verbatim copies of the Program's
95: source code as you receive it, in any medium, provided that you
96: conspicuously and appropriately publish on each copy an appropriate
97: copyright notice and disclaimer of warranty; keep intact all the
98: notices that refer to this License and to the absence of any warranty;
99: and give any other recipients of the Program a copy of this License
100: along with the Program.
101:
102: You may charge a fee for the physical act of transferring a copy, and
103: you may at your option offer warranty protection in exchange for a fee.
104:
105: 2. You may modify your copy or copies of the Program or any portion
106: of it, thus forming a work based on the Program, and copy and
107: distribute such modifications or work under the terms of Section 1
108: above, provided that you also meet all of these conditions:
109:
110: a) You must cause the modified files to carry prominent notices
111: stating that you changed the files and the date of any change.
112:
113: b) You must cause any work that you distribute or publish, that in
114: whole or in part contains or is derived from the Program or any
115: part thereof, to be licensed as a whole at no charge to all third
116: parties under the terms of this License.
117:
118: c) If the modified program normally reads commands interactively
119: when run, you must cause it, when started running for such
120: interactive use in the most ordinary way, to print or display an
121: announcement including an appropriate copyright notice and a
122: notice that there is no warranty (or else, saying that you provide
123: a warranty) and that users may redistribute the program under
124: these conditions, and telling the user how to view a copy of this
125: License. (Exception: if the Program itself is interactive but
126: does not normally print such an announcement, your work based on
127: the Program is not required to print an announcement.)
128:
129: These requirements apply to the modified work as a whole. If
130: identifiable sections of that work are not derived from the Program,
131: and can be reasonably considered independent and separate works in
132: themselves, then this License, and its terms, do not apply to those
133: sections when you distribute them as separate works. But when you
134: distribute the same sections as part of a whole which is a work based
135: on the Program, the distribution of the whole must be on the terms of
136: this License, whose permissions for other licensees extend to the
137: entire whole, and thus to each and every part regardless of who wrote it.
138:
139: Thus, it is not the intent of this section to claim rights or contest
140: your rights to work written entirely by you; rather, the intent is to
141: exercise the right to control the distribution of derivative or
142: collective works based on the Program.
143:
144: In addition, mere aggregation of another work not based on the Program
145: with the Program (or with a work based on the Program) on a volume of
146: a storage or distribution medium does not bring the other work under
147: the scope of this License.
148:
149: 3. You may copy and distribute the Program (or a work based on it,
150: under Section 2) in object code or executable form under the terms of
151: Sections 1 and 2 above provided that you also do one of the following:
152:
153: a) Accompany it with the complete corresponding machine-readable
154: source code, which must be distributed under the terms of Sections
155: 1 and 2 above on a medium customarily used for software interchange; or,
156:
157: b) Accompany it with a written offer, valid for at least three
158: years, to give any third party, for a charge no more than your
159: cost of physically performing source distribution, a complete
160: machine-readable copy of the corresponding source code, to be
161: distributed under the terms of Sections 1 and 2 above on a medium
162: customarily used for software interchange; or,
163:
164: c) Accompany it with the information you received as to the offer
165: to distribute corresponding source code. (This alternative is
166: allowed only for noncommercial distribution and only if you
167: received the program in object code or executable form with such
168: an offer, in accord with Subsection b above.)
169:
170: The source code for a work means the preferred form of the work for
171: making modifications to it. For an executable work, complete source
172: code means all the source code for all modules it contains, plus any
173: associated interface definition files, plus the scripts used to
174: control compilation and installation of the executable. However, as a
175: special exception, the source code distributed need not include
176: anything that is normally distributed (in either source or binary
177: form) with the major components (compiler, kernel, and so on) of the
178: operating system on which the executable runs, unless that component
179: itself accompanies the executable.
180:
181: If distribution of executable or object code is made by offering
182: access to copy from a designated place, then offering equivalent
183: access to copy the source code from the same place counts as
184: distribution of the source code, even though third parties are not
185: compelled to copy the source along with the object code.
186:
187: 4. You may not copy, modify, sublicense, or distribute the Program
188: except as expressly provided under this License. Any attempt
189: otherwise to copy, modify, sublicense or distribute the Program is
190: void, and will automatically terminate your rights under this License.
191: However, parties who have received copies, or rights, from you under
192: this License will not have their licenses terminated so long as such
193: parties remain in full compliance.
194:
195: 5. You are not required to accept this License, since you have not
196: signed it. However, nothing else grants you permission to modify or
197: distribute the Program or its derivative works. These actions are
198: prohibited by law if you do not accept this License. Therefore, by
199: modifying or distributing the Program (or any work based on the
200: Program), you indicate your acceptance of this License to do so, and
201: all its terms and conditions for copying, distributing or modifying
202: the Program or works based on it.
203:
204: 6. Each time you redistribute the Program (or any work based on the
205: Program), the recipient automatically receives a license from the
206: original licensor to copy, distribute or modify the Program subject to
207: these terms and conditions. You may not impose any further
208: restrictions on the recipients' exercise of the rights granted herein.
209: You are not responsible for enforcing compliance by third parties to
210: this License.
211:
212: 7. If, as a consequence of a court judgment or allegation of patent
213: infringement or for any other reason (not limited to patent issues),
214: conditions are imposed on you (whether by court order, agreement or
215: otherwise) that contradict the conditions of this License, they do not
216: excuse you from the conditions of this License. If you cannot
217: distribute so as to satisfy simultaneously your obligations under this
218: License and any other pertinent obligations, then as a consequence you
219: may not distribute the Program at all. For example, if a patent
220: license would not permit royalty-free redistribution of the Program by
221: all those who receive copies directly or indirectly through you, then
222: the only way you could satisfy both it and this License would be to
223: refrain entirely from distribution of the Program.
224:
225: If any portion of this section is held invalid or unenforceable under
226: any particular circumstance, the balance of the section is intended to
227: apply and the section as a whole is intended to apply in other
228: circumstances.
229:
230: It is not the purpose of this section to induce you to infringe any
231: patents or other property right claims or to contest validity of any
232: such claims; this section has the sole purpose of protecting the
233: integrity of the free software distribution system, which is
234: implemented by public license practices. Many people have made
235: generous contributions to the wide range of software distributed
236: through that system in reliance on consistent application of that
237: system; it is up to the author/donor to decide if he or she is willing
238: to distribute software through any other system and a licensee cannot
239: impose that choice.
240:
241: This section is intended to make thoroughly clear what is believed to
242: be a consequence of the rest of this License.
243:
244: 8. If the distribution and/or use of the Program is restricted in
245: certain countries either by patents or by copyrighted interfaces, the
246: original copyright holder who places the Program under this License
247: may add an explicit geographical distribution limitation excluding
248: those countries, so that distribution is permitted only in or among
249: countries not thus excluded. In such case, this License incorporates
250: the limitation as if written in the body of this License.
251:
252: 9. The Free Software Foundation may publish revised and/or new versions
253: of the General Public License from time to time. Such new versions will
254: be similar in spirit to the present version, but may differ in detail to
255: address new problems or concerns.
256:
257: Each version is given a distinguishing version number. If the Program
258: specifies a version number of this License which applies to it and "any
259: later version", you have the option of following the terms and conditions
260: either of that version or of any later version published by the Free
261: Software Foundation. If the Program does not specify a version number of
262: this License, you may choose any version ever published by the Free Software
263: Foundation.
264:
265: 10. If you wish to incorporate parts of the Program into other free
266: programs whose distribution conditions are different, write to the author
267: to ask for permission. For software which is copyrighted by the Free
268: Software Foundation, write to the Free Software Foundation; we sometimes
269: make exceptions for this. Our decision will be guided by the two goals
270: of preserving the free status of all derivatives of our free software and
271: of promoting the sharing and reuse of software generally.
272:
273: NO WARRANTY
274:
275: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
276: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
277: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
278: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
279: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
280: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
281: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
282: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
283: REPAIR OR CORRECTION.
284:
285: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
286: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
287: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
288: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
289: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
290: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
291: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
292: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
293: POSSIBILITY OF SUCH DAMAGES.
294:
295: END OF TERMS AND CONDITIONS
296:
297: How to Apply These Terms to Your New Programs
298:
299: If you develop a new program, and you want it to be of the greatest
300: possible use to the public, the best way to achieve this is to make it
301: free software which everyone can redistribute and change under these terms.
302:
303: To do so, attach the following notices to the program. It is safest
304: to attach them to the start of each source file to most effectively
305: convey the exclusion of warranty; and each file should have at least
306: the "copyright" line and a pointer to where the full notice is found.
307:
308: <one line to give the program's name and a brief idea of what it does.>
309: Copyright (C) <year> <name of author>
310:
311: This program is free software; you can redistribute it and/or modify
312: it under the terms of the GNU General Public License as published by
313: the Free Software Foundation; either version 2 of the License, or
314: (at your option) any later version.
315:
316: This program is distributed in the hope that it will be useful,
317: but WITHOUT ANY WARRANTY; without even the implied warranty of
318: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
319: GNU General Public License for more details.
320:
321: You should have received a copy of the GNU General Public License
322: along with this program; if not, write to the Free Software
323: Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA, 02110-1301 USA
324:
325:
326: Also add information on how to contact you by electronic and paper mail.
327:
328: If the program is interactive, make it output a short notice like this
329: when it starts in an interactive mode:
330:
331: Gnomovision version 69, Copyright (C) year name of author
332: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
333: This is free software, and you are welcome to redistribute it
334: under certain conditions; type `show c' for details.
335:
336: The hypothetical commands `show w' and `show c' should show the appropriate
337: parts of the General Public License. Of course, the commands you use may
338: be called something other than `show w' and `show c'; they could even be
339: mouse-clicks or menu items--whatever suits your program.
340:
341: You should also get your employer (if you work as a programmer) or your
342: school, if any, to sign a "copyright disclaimer" for the program, if
343: necessary. Here is a sample; alter the names:
344:
345: Yoyodyne, Inc., hereby disclaims all copyright interest in the program
346: `Gnomovision' (which makes passes at compilers) written by James Hacker.
347:

349: Ty Coon, President of Vice
350:
351: This General Public License does not permit incorporating your program into
352: proprietary programs. If your program is a subroutine library, you may
353: consider it more useful to permit linking proprietary applications with the
354: library. If this is what you want to do, use the GNU Library General
355: Public License instead of this License.
