24 Version 2, June 1991
25
26 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
27 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
28 Everyone is permitted to copy and distribute verbatim copies
29 of this license document, but changing it is not allowed.
30
31 Preamble
32
33 The licenses for most software are designed to take away your
34 freedom to share and change it. By contrast, the GNU General Public
35 License is intended to guarantee your freedom to share and change free
36 software--to make sure the software is free for all its users. This
37 General Public License applies to most of the Free Software
38 Foundation's software and to any other program whose authors commit to
39 using it. (Some other Free Software Foundation software is covered by
40 the GNU Library General Public License instead.) You can apply it to
41 your programs, too.
42
43 When we speak of free software, we are referring to freedom, not
44 price. Our General Public Licenses are designed to make sure that you
45 have the freedom to distribute copies of free software (and charge for
46 this service if you wish), that you receive source code or can get it
47 if you want it, that you can change the software or use pieces of it
48 in new free programs; and that you know you can do these things.
49
50 To protect your rights, we need to make restrictions that forbid
51 anyone to deny you these rights or to ask you to surrender the rights.
52 These restrictions translate to certain responsibilities for you if you
53 distribute copies of the software, or if you modify it.
54
55 For example, if you distribute copies of such a program, whether
56 gratis or for a fee, you must give the recipients all the rights that
57 you have. You must make sure that they, too, receive or can get the
58 source code. And you must show them these terms so they know their
59 rights.
60
61 We protect your rights with two steps: (1) copyright the software, and
62 (2) offer you this license which gives you legal permission to copy,
63 distribute and/or modify the software.
64
65 Also, for each author's protection and ours, we want to make certain
66 that everyone understands that there is no warranty for this free
67 software. If the software is modified by someone else and passed on, we
68 want its recipients to know that what they have is not the original, so
69 that any problems introduced by others will not reflect on the original
70 authors' reputations.
71
72 Finally, any free program is threatened constantly by software
73 patents. We wish to avoid the danger that redistributors of a free
74 program will individually obtain patent licenses, in effect making the
75 program proprietary. To prevent this, we have made it clear that any
76 patent must be licensed for everyone's free use or not licensed at all.
77
78 The precise terms and conditions for copying, distribution and
79 modification follow.

81 GNU GENERAL PUBLIC LICENSE
82 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
83
84 0. This License applies to any program or other work which contains
85 a notice placed by the copyright holder saying it may be distributed
86 under the terms of this General Public License. The "Program", below,
87 refers to any such program or work, and a "work based on the Program"
88 means either the Program or any derivative work under copyright law:
89 that is to say, a work containing the Program or a portion of it,
90 either verbatim or with modifications and/or translated into another
91 language. (Hereinafter, translation is included without limitation in
92 the term "modification".) Each licensee is addressed as "you".
93
94 Activities other than copying, distribution and modification are not
95 covered by this License; they are outside its scope. The act of
96 running the Program is not restricted, and the output from the Program
97 is covered only if its contents constitute a work based on the
98 Program (independent of having been made by running the Program).
99 Whether that is true depends on what the Program does.
100
101 1. You may copy and distribute verbatim copies of the Program's
102 source code as you receive it, in any medium, provided that you
103 conspicuously and appropriately publish on each copy an appropriate
104 copyright notice and disclaimer of warranty; keep intact all the
105 notices that refer to this License and to the absence of any warranty;
106 and give any other recipients of the Program a copy of this License
107 along with the Program.
108
109 You may charge a fee for the physical act of transferring a copy, and
110 you may at your option offer warranty protection in exchange for a fee.
111
112 2. You may modify your copy or copies of the Program or any portion
113 of it, thus forming a work based on the Program, and copy and
114 distribute such modifications or work under the terms of Section 1
115 above, provided that you also meet all of these conditions:
116
117 a) You must cause the modified files to carry prominent notices
118 stating that you changed the files and the date of any change.
119
120 b) You must cause any work that you distribute or publish, that in
121 whole or in part contains or is derived from the Program or any
122 part thereof, to be licensed as a whole at no charge to all third
123 parties under the terms of this License.
124
125 c) If the modified program normally reads commands interactively
126 when run, you must cause it, when started running for such
127 interactive use in the most ordinary way, to print or display an
128 announcement including an appropriate copyright notice and a
129 notice that there is no warranty (or else, saying that you provide
130 a warranty) and that users may redistribute the program under
131 these conditions, and telling the user how to view a copy of this
132 License. (Exception: if the Program itself is interactive but
133 does not normally print such an announcement, your work based on
134 the Program is not required to print an announcement.)

135
50298f4 @spearce Switch the license from BSD to GPL+libgcc exception
spearce authored
136 These requirements apply to the modified work as a whole. If
137 identifiable sections of that work are not derived from the Program,
138 and can be reasonably considered independent and separate works in
139 themselves, then this License, and its terms, do not apply to those
140 sections when you distribute them as separate works. But when you
141 distribute the same sections as part of a whole which is a work based
142 on the Program, the distribution of the whole must be on the terms of
143 this License, whose permissions for other licensees extend to the
144 entire whole, and thus to each and every part regardless of who wrote it.
145
146 Thus, it is not the intent of this section to claim rights or contest
147 your rights to work written entirely by you; rather, the intent is to
148 exercise the right to control the distribution of derivative or
149 collective works based on the Program.
150
151 In addition, mere aggregation of another work not based on the Program
152 with the Program (or with a work based on the Program) on a volume of
153 a storage or distribution medium does not bring the other work under
154 the scope of this License.
155
156 3. You may copy and distribute the Program (or a work based on it,
157 under Section 2) in object code or executable form under the terms of
158 Sections 1 and 2 above provided that you also do one of the following:
159
160 a) Accompany it with the complete corresponding machine-readable
161 source code, which must be distributed under the terms of Sections
162 1 and 2 above on a medium customarily used for software interchange; or,
163
164 b) Accompany it with a written offer, valid for at least three
165 years, to give any third party, for a charge no more than your
166 cost of physically performing source distribution, a complete
167 machine-readable copy of the corresponding source code, to be
168 distributed under the terms of Sections 1 and 2 above on a medium
169 customarily used for software interchange; or,
170
171 c) Accompany it with the information you received as to the offer
172 to distribute corresponding source code. (This alternative is
173 allowed only for noncommercial distribution and only if you
174 received the program in object code or executable form with such
175 an offer, in accord with Subsection b above.)
176
177 The source code for a work means the preferred form of the work for
178 making modifications to it. For an executable work, complete source
179 code means all the source code for all modules it contains, plus any
180 associated interface definition files, plus the scripts used to
181 control compilation and installation of the executable. However, as a
182 special exception, the source code distributed need not include
183 anything that is normally distributed (in either source or binary
184 form) with the major components (compiler, kernel, and so on) of the
185 operating system on which the executable runs, unless that component
186 itself accompanies the executable.
187
188 If distribution of executable or object code is made by offering
189 access to copy from a designated place, then offering equivalent
190 access to copy the source code from the same place counts as
191 distribution of the source code, even though third parties are not
192 compelled to copy the source along with the object code.

194 4. You may not copy, modify, sublicense, or distribute the Program
195 except as expressly provided under this License. Any attempt
196 otherwise to copy, modify, sublicense or distribute the Program is
197 void, and will automatically terminate your rights under this License.
198 However, parties who have received copies, or rights, from you under
199 this License will not have their licenses terminated so long as such
200 parties remain in full compliance.
201
202 5. You are not required to accept this License, since you have not
203 signed it. However, nothing else grants you permission to modify or
204 distribute the Program or its derivative works. These actions are
205 prohibited by law if you do not accept this License. Therefore, by
206 modifying or distributing the Program (or any work based on the
207 Program), you indicate your acceptance of this License to do so, and
208 all its terms and conditions for copying, distributing or modifying
209 the Program or works based on it.
210
211 6. Each time you redistribute the Program (or any work based on the
212 Program), the recipient automatically receives a license from the
213 original licensor to copy, distribute or modify the Program subject to
214 these terms and conditions. You may not impose any further
215 restrictions on the recipients' exercise of the rights granted herein.
216 You are not responsible for enforcing compliance by third parties to
217 this License.
218
219 7. If, as a consequence of a court judgment or allegation of patent
220 infringement or for any other reason (not limited to patent issues),
221 conditions are imposed on you (whether by court order, agreement or
222 otherwise) that contradict the conditions of this License, they do not
223 excuse you from the conditions of this License. If you cannot
224 distribute so as to satisfy simultaneously your obligations under this
225 License and any other pertinent obligations, then as a consequence you
226 may not distribute the Program at all. For example, if a patent
227 license would not permit royalty-free redistribution of the Program by
228 all those who receive copies directly or indirectly through you, then
229 the only way you could satisfy both it and this License would be to
230 refrain entirely from distribution of the Program.
231
232 If any portion of this section is held invalid or unenforceable under
233 any particular circumstance, the balance of the section is intended to
234 apply and the section as a whole is intended to apply in other
235 circumstances.
236
237 It is not the purpose of this section to induce you to infringe any
238 patents or other property right claims or to contest validity of any
239 such claims; this section has the sole purpose of protecting the
240 integrity of the free software distribution system, which is
241 implemented by public license practices. Many people have made
242 generous contributions to the wide range of software distributed
243 through that system in reliance on consistent application of that
244 system; it is up to the author/donor to decide if he or she is willing
245 to distribute software through any other system and a licensee cannot
246 impose that choice.
247
248 This section is intended to make thoroughly clear what is believed to
249 be a consequence of the rest of this License.

251 8. If the distribution and/or use of the Program is restricted in
252 certain countries either by patents or by copyrighted interfaces, the
253 original copyright holder who places the Program under this License
254 may add an explicit geographical distribution limitation excluding
255 those countries, so that distribution is permitted only in or among
256 countries not thus excluded. In such case, this License incorporates
257 the limitation as if written in the body of this License.
258
259 9. The Free Software Foundation may publish revised and/or new versions
260 of the General Public License from time to time. Such new versions will
261 be similar in spirit to the present version, but may differ in detail to
262 address new problems or concerns.
263
264 Each version is given a distinguishing version number. If the Program
265 specifies a version number of this License which applies to it and "any
266 later version", you have the option of following the terms and conditions
267 either of that version or of any later version published by the Free
268 Software Foundation. If the Program does not specify a version number of
269 this License, you may choose any version ever published by the Free Software
270 Foundation.
271
272 10. If you wish to incorporate parts of the Program into other free
273 programs whose distribution conditions are different, write to the author
274 to ask for permission. For software which is copyrighted by the Free
275 Software Foundation, write to the Free Software Foundation; we sometimes
276 make exceptions for this. Our decision will be guided by the two goals
277 of preserving the free status of all derivatives of our free software and
278 of promoting the sharing and reuse of software generally.
279
280 NO WARRANTY
281
282 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
283 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
284 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
285 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
286 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
287 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
288 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
289 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
290 REPAIR OR CORRECTION.
291
292 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
293 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
294 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
295 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
296 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
297 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
298 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
299 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
300 POSSIBILITY OF SUCH DAMAGES.

304 How to Apply These Terms to Your New Programs
305
306 If you develop a new program, and you want it to be of the greatest
307 possible use to the public, the best way to achieve this is to make it
308 free software which everyone can redistribute and change under these terms.
309
310 To do so, attach the following notices to the program. It is safest
311 to attach them to the start of each source file to most effectively
312 convey the exclusion of warranty; and each file should have at least
313 the "copyright" line and a pointer to where the full notice is found.
314
315 <one line to give the program's name and a brief idea of what it does.>
316 Copyright (C) <year> <name of author>
317
318 This program is free software; you can redistribute it and/or modify
319 it under the terms of the GNU General Public License as published by
320 the Free Software Foundation; either version 2 of the License, or
321 (at your option) any later version.
322
323 This program is distributed in the hope that it will be useful,
324 but WITHOUT ANY WARRANTY; without even the implied warranty of
325 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
326 GNU General Public License for more details.
327
328 You should have received a copy of the GNU General Public License
329 along with this program; if not, write to the Free Software
330 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
331
332
333 Also add information on how to contact you by electronic and paper mail.
334
335 If the program is interactive, make it output a short notice like this
336 when it starts in an interactive mode:
337
338 Gnomovision version 69, Copyright (C) year name of author
339 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
340 This is free software, and you are welcome to redistribute it
341 under certain conditions; type `show c' for details.
342
343 The hypothetical commands `show w' and `show c' should show the appropriate
344 parts of the General Public License. Of course, the commands you use may
345 be called something other than `show w' and `show c'; they could even be
346 mouse-clicks or menu items--whatever suits your program.
347
348 You should also get your employer (if you work as a programmer) or your
349 school, if any, to sign a "copyright disclaimer" for the program, if
350 necessary. Here is a sample; alter the names:
351
352 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
353 `Gnomovision' (which makes passes at compilers) written by James Hacker.
354
355 <signature of Ty Coon>, 1 April 1989
356 Ty Coon, President of Vice
357
358 This General Public License does not permit incorporating your program into
359 proprietary programs. If your program is a subroutine library, you may
360 consider it more useful to permit linking proprietary applications with the
361 library. If this is what you want to do, use the GNU Library General
362 Public License instead of this License.
