apply GPL v2-or-later

This is the lazy part, just the COPYING file. Non-paranoids
will be satisfied with this. Properly we should add a short
header to each file. I'll procrastinate that until we have
a final name, so we don't have to do it twice.

16                       Version 2, June 1991
17
18 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
19 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
20 Everyone is permitted to copy and distribute verbatim copies
21 of this license document, but changing it is not allowed.
22
23                            Preamble
24
25  The licenses for most software are designed to take away your
26freedom to share and change it.  By contrast, the GNU General Public
27License is intended to guarantee your freedom to share and change free
28software--to make sure the software is free for all its users.  This
29General Public License applies to most of the Free Software
30Foundation's software and to any other program whose authors commit to
31using it.  (Some other Free Software Foundation software is covered by
32the GNU Lesser General Public License instead.)  You can apply it to
33your programs, too.
34
35  When we speak of free software, we are referring to freedom, not
36price.  Our General Public Licenses are designed to make sure that you
37have the freedom to distribute copies of free software (and charge for
38this service if you wish), that you receive source code or can get it
39if you want it, that you can change the software or use pieces of it
40in new free programs; and that you know you can do these things.
41
42  To protect your rights, we need to make restrictions that forbid
43anyone to deny you these rights or to ask you to surrender the rights.
44These restrictions translate to certain responsibilities for you if you
45distribute copies of the software, or if you modify it.
46
47  For example, if you distribute copies of such a program, whether
48gratis or for a fee, you must give the recipients all the rights that
49you have.  You must make sure that they, too, receive or can get the
50source code.  And you must show them these terms so they know their
51rights.
52
53  We protect your rights with two steps: (1) copyright the software, and
54(2) offer you this license which gives you legal permission to copy,
55distribute and/or modify the software.
56
57  Also, for each author's protection and ours, we want to make certain
58that everyone understands that there is no warranty for this free
59software.  If the software is modified by someone else and passed on, we
60want its recipients to know that what they have is not the original, so
61that any problems introduced by others will not reflect on the original
62authors' reputations.
63
64  Finally, any free program is threatened constantly by software
65patents.  We wish to avoid the danger that redistributors of a free
66program will individually obtain patent licenses, in effect making the
67program proprietary.  To prevent this, we have made it clear that any
68patent must be licensed for everyone's free use or not licensed at all.
69
70  The precise terms and conditions for copying, distribution and
71modification follow.
72
73                    GNU GENERAL PUBLIC LICENSE
74   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
75
76  0. This License applies to any program or other work which contains
77a notice placed by the copyright holder saying it may be distributed
78under the terms of this General Public License.  The "Program", below,
79refers to any such program or work, and a "work based on the Program"
80means either the Program or any derivative work under copyright law:
81that is to say, a work containing the Program or a portion of it,
82either verbatim or with modifications and/or translated into another
83language.  (Hereinafter, translation is included without limitation in
84the term "modification".)  Each licensee is addressed as "you".
85
86Activities other than copying, distribution and modification are not
87covered by this License; they are outside its scope.  The act of
88running the Program is not restricted, and the output from the Program
89is covered only if its contents constitute a work based on the
90Program (independent of having been made by running the Program).
91Whether that is true depends on what the Program does.
92
93  1. You may copy and distribute verbatim copies of the Program's
94source code as you receive it, in any medium, provided that you
95conspicuously and appropriately publish on each copy an appropriate
96copyright notice and disclaimer of warranty; keep intact all the
97notices that refer to this License and to the absence of any warranty;
98and give any other recipients of the Program a copy of this License
99along with the Program.
100
101You may charge a fee for the physical act of transferring a copy, and
102you may at your option offer warranty protection in exchange for a fee.
103
104  2. You may modify your copy or copies of the Program or any portion
105of it, thus forming a work based on the Program, and copy and
106distribute such modifications or work under the terms of Section 1
107above, provided that you also meet all of these conditions:
108
109    a) You must cause the modified files to carry prominent notices
110    stating that you changed the files and the date of any change.
111
112    b) You must cause any work that you distribute or publish, that in
113    whole or in part contains or is derived from the Program or any
114    part thereof, to be licensed as a whole at no charge to all third
115    parties under the terms of this License.
116
117    c) If the modified program normally reads commands interactively
118    when run, you must cause it, when started running for such
119    interactive use in the most ordinary way, to print or display an
120    announcement including an appropriate copyright notice and a
121    notice that there is no warranty (or else, saying that you provide
122    a warranty) and that users may redistribute the program under
123    these conditions, and telling the user how to view a copy of this
124    License.  (Exception: if the Program itself is interactive but
125    does not normally print such an announcement, your work based on
126    the Program is not required to print an announcement.)
127
128These requirements apply to the modified work as a whole.  If
129identifiable sections of that work are not derived from the Program,
130and can be reasonably considered independent and separate works in
131themselves, then this License, and its terms, do not apply to those
132sections when you distribute them as separate works.  But when you
133distribute the same sections as part of a whole which is a work based
134on the Program, the distribution of the whole must be on the terms of
135this License, whose permissions for other licensees extend to the
136entire whole, and thus to each and every part regardless of who wrote it.
137
138Thus, it is not the intent of this section to claim rights or contest
139your rights to work written entirely by you; rather, the intent is to
140exercise the right to control the distribution of derivative or
141collective works based on the Program.
142
143In addition, mere aggregation of another work not based on the Program
144with the Program (or with a work based on the Program) on a volume of
145a storage or distribution medium does not bring the other work under
146the scope of this License.
147
148  3. You may copy and distribute the Program (or a work based on it,
149under Section 2) in object code or executable form under the terms of
150Sections 1 and 2 above provided that you also do one of the following:
151
152    a) Accompany it with the complete corresponding machine-readable
153    source code, which must be distributed under the terms of Sections
154    1 and 2 above on a medium customarily used for software interchange; or,
155
156    b) Accompany it with a written offer, valid for at least three
157    years, to give any third party, for a charge no more than your
158    cost of physically performing source distribution, a complete
159    machine-readable copy of the corresponding source code, to be
160    distributed under the terms of Sections 1 and 2 above on a medium
161    customarily used for software interchange; or,
162
163    c) Accompany it with the information you received as to the offer
164    to distribute corresponding source code.  (This alternative is
165    allowed only for noncommercial distribution and only if you
166    received the program in object code or executable form with such
167    an offer, in accord with Subsection b above.)
168
169The source code for a work means the preferred form of the work for
170making modifications to it.  For an executable work, complete source
171code means all the source code for all modules it contains, plus any
172associated interface definition files, plus the scripts used to
173control compilation and installation of the executable.  However, as a
174special exception, the source code distributed need not include
175anything that is normally distributed (in either source or binary
176form) with the major components (compiler, kernel, and so on) of the
177operating system on which the executable runs, unless that component
178itself accompanies the executable.
179
180If distribution of executable or object code is made by offering
181access to copy from a designated place, then offering equivalent
182access to copy the source code from the same place counts as
183distribution of the source code, even though third parties are not
184compelled to copy the source along with the object code.
185
186  4. You may not copy, modify, sublicense, or distribute the Program
187except as expressly provided under this License.  Any attempt
188otherwise to copy, modify, sublicense or distribute the Program is
189void, and will automatically terminate your rights under this License.
190However, parties who have received copies, or rights, from you under
191this License will not have their licenses terminated so long as such
192parties remain in full compliance.
193
194  5. You are not required to accept this License, since you have not
195signed it.  However, nothing else grants you permission to modify or
196distribute the Program or its derivative works.  These actions are
197prohibited by law if you do not accept this License.  Therefore, by
198modifying or distributing the Program (or any work based on the
199Program), you indicate your acceptance of this License to do so, and
200all its terms and conditions for copying, distributing or modifying
201the Program or works based on it.
202
203  6. Each time you redistribute the Program (or any work based on the
204Program), the recipient automatically receives a license from the
205original licensor to copy, distribute or modify the Program subject to
206these terms and conditions.  You may not impose any further
207restrictions on the recipients' exercise of the rights granted herein.
208You are not responsible for enforcing compliance by third parties to
209this License.
210
211  7. If, as a consequence of a court judgment or allegation of patent
212infringement or for any other reason (not limited to patent issues),
213conditions are imposed on you (whether by court order, agreement or
214otherwise) that contradict the conditions of this License, they do not
215excuse you from the conditions of this License.  If you cannot
216distribute so as to satisfy simultaneously your obligations under this
217License and any other pertinent obligations, then as a consequence you
218may not distribute the Program at all.  For example, if a patent
219license would not permit royalty-free redistribution of the Program by
220all those who receive copies directly or indirectly through you, then
221the only way you could satisfy both it and this License would be to
222refrain entirely from distribution of the Program.
223
224If any portion of this section is held invalid or unenforceable under
225any particular circumstance, the balance of the section is intended to
226apply and the section as a whole is intended to apply in other
227circumstances.
228
229It is not the purpose of this section to induce you to infringe any
230patents or other property right claims or to contest validity of any
231such claims; this section has the sole purpose of protecting the
232integrity of the free software distribution system, which is
233implemented by public license practices.  Many people have made
234generous contributions to the wide range of software distributed
235through that system in reliance on consistent application of that
236system; it is up to the author/donor to decide if he or she is willing
237to distribute software through any other system and a licensee cannot
238impose that choice.
239
240This section is intended to make thoroughly clear what is believed to
241be a consequence of the rest of this License.
242
243  8. If the distribution and/or use of the Program is restricted in
244certain countries either by patents or by copyrighted interfaces, the
245original copyright holder who places the Program under this License
246may add an explicit geographical distribution limitation excluding
247those countries, so that distribution is permitted only in or among
248countries not thus excluded.  In such case, this License incorporates
249the limitation as if written in the body of this License.
250
251  9. The Free Software Foundation may publish revised and/or new versions
252of the General Public License from time to time.  Such new versions will
253be similar in spirit to the present version, but may differ in detail to
254address new problems or concerns.
255
256Each version is given a distinguishing version number.  If the Program
257specifies a version number of this License which applies to it and "any
258later version", you have the option of following the terms and conditions
259either of that version or of any later version published by the Free
260Software Foundation.  If the Program does not specify a version number of
261this License, you may choose any version ever published by the Free Software
262Foundation.
263
264  10. If you wish to incorporate parts of the Program into other free
265programs whose distribution conditions are different, write to the author
266to ask for permission.  For software which is copyrighted by the Free
267Software Foundation, write to the Free Software Foundation; we sometimes
268make exceptions for this.  Our decision will be guided by the two goals
269of preserving the free status of all derivatives of our free software and
270of promoting the sharing and reuse of software generally.
271
272                            NO WARRANTY
273
274  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
275FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
276OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
277PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
278OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
279MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
280TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
281PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
282REPAIR OR CORRECTION.
283
284  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
285WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
286REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
287INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
288OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
289TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
290YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
291PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
292POSSIBILITY OF SUCH DAMAGES.
293
294                     END OF TERMS AND CONDITIONS
295
296            How to Apply These Terms to Your New Programs
297
298  If you develop a new program, and you want it to be of the greatest
299possible use to the public, the best way to achieve this is to make it
300free software which everyone can redistribute and change under these terms.
301
302  To do so, attach the following notices to the program.  It is safest
303to attach them to the start of each source file to most effectively
304convey the exclusion of warranty; and each file should have at least
305the "copyright" line and a pointer to where the full notice is found.
306
307    <one line to give the program's name and a brief idea of what it does.>
308    Copyright (C) <year>  <name of author>
309
310    This program is free software; you can redistribute it and/or modify
311    it under the terms of the GNU General Public License as published by
312    the Free Software Foundation; either version 2 of the License, or
313    (at your option) any later version.
314
315    This program is distributed in the hope that it will be useful,
316    but WITHOUT ANY WARRANTY; without even the implied warranty of
317    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
318    GNU General Public License for more details.
319
320    You should have received a copy of the GNU General Public License along
321    with this program; if not, write to the Free Software Foundation, Inc.,
322    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
323
324Also add information on how to contact you by electronic and paper mail.
325
326If the program is interactive, make it output a short notice like this
327when it starts in an interactive mode:
328
329    Gnomovision version 69, Copyright (C) year name of author
330    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
331    This is free software, and you are welcome to redistribute it
332    under certain conditions; type `show c' for details.
333
334The hypothetical commands `show w' and `show c' should show the appropriate
335parts of the General Public License.  Of course, the commands you use may
336be called something other than `show w' and `show c'; they could even be
337mouse-clicks or menu items--whatever suits your program.
338
339You should also get your employer (if you work as a programmer) or your
340school, if any, to sign a "copyright disclaimer" for the program, if
341necessary.  Here is a sample; alter the names:
342
343  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
344  `Gnomovision' (which makes passes at compilers) written by James Hacker.
345
346  <signature of Ty Coon>, 1 April 1989
347  Ty Coon, President of Vice
348
349This General Public License does not permit incorporating your program into
350proprietary programs.  If your program is a subroutine library, you may
351consider it more useful to permit linking proprietary applications with the
352library.  If this is what you want to do, use the GNU Lesser General
353Public License instead of this License.
