 Copyright (C) 1989, 1991 Free Software Foundation, Inc. <http://fsf.org/>

 Everyone is permitted to copy and distribute verbatim copies
6
 of this license document, but changing it is not allowed.

                            Preamble
9
10
  The licenses for most software are designed to take away your
11
freedom to share and change it.  By contrast, the GNU General Public
12
License is intended to guarantee your freedom to share and change free
13
software--to make sure the software is free for all its users.  This
14
General Public License applies to most of the Free Software
15
Foundation's software and to any other program whose authors commit to
16
using it.  (Some other Free Software Foundation software is covered by
17
the GNU Library General Public License instead.)  You can apply it to
18
your programs, too.
19
20
  When we speak of free software, we are referring to freedom, not
21
price.  Our General Public Licenses are designed to make sure that you
22
have the freedom to distribute copies of free software (and charge for
23
this service if you wish), that you receive source code or can get it
24
if you want it, that you can change the software or use pieces of it
25
in new free programs; and that you know you can do these things.
26
27
  To protect your rights, we need to make restrictions that forbid
28
anyone to deny you these rights or to ask you to surrender the rights.
29
These restrictions translate to certain responsibilities for you if you
30
distribute copies of the software, or if you modify it.
31
32
  For example, if you distribute copies of such a program, whether
33
gratis or for a fee, you must give the recipients all the rights that
34
you have.  You must make sure that they, too, receive or can get the
35
source code.  And you must show them these terms so they know their
36
rights.
37
38
  We protect your rights with two steps: (1) copyright the software, and
39
(2) offer you this license which gives you legal permission to copy,
40
distribute and/or modify the software.
41
42
  Also, for each author's protection and ours, we want to make certain
43
that everyone understands that there is no warranty for this free
44
software.  If the software is modified by someone else and passed on, we
45
want its recipients to know that what they have is not the original, so
46
that any problems introduced by others will not reflect on the original
47
authors' reputations.
48
49
  Finally, any free program is threatened constantly by software
50
patents.  We wish to avoid the danger that redistributors of a free
51
program will individually obtain patent licenses, in effect making the
52
program proprietary.  To prevent this, we have made it clear that any
53
patent must be licensed for everyone's free use or not licensed at all.
54
55
  The precise terms and conditions for copying, distribution and
56
modification follow.

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

332
333
This General Public License does not permit incorporating your program into
334
proprietary programs.  If your program is a subroutine library, you may
335
consider it more useful to permit linking proprietary applications with the
336
library.  If this is what you want to do, use the GNU Library General
337
Public License instead of this License.
