that everyone understands that there is no warranty for this free

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
62
0. This License applies to any program or other work which contains a
63
notice placed by the copyright holder saying it may be distributed
64
under the terms of this General Public License. The "Program",
65
below, refers to any such program or work, and a "work based on
66
the Program" means either the Program or any derivative work under
67
copyright law: that is to say, a work containing the Program or a
68
portion of it, either verbatim or with modifications and/or
69
translated into another language. (Hereinafter, translation is
70
included without limitation in the term "modification".) Each
71
licensee is addressed as "you".
73
Activities other than copying, distribution and modification are
74
not covered by this License; they are outside its scope. The act
75
of running the Program is not restricted, and the output from the
76
Program is covered only if its contents constitute a work based on
77
the Program (independent of having been made by running the
78
Program). Whether that is true depends on what the Program does.

a notice placed by the copyright holder saying it may be distributed
64
under the terms of this General Public License. The "Program", below,
65
refers to any such program or work, and a "work based on the Program"
66
means either the Program or any derivative work under copyright law:
67
that is to say, a work containing the Program or a portion of it,
68
either verbatim or with modifications and/or translated into another
69
language. (Hereinafter, translation is included without limitation in
70
the term "modification".) Each licensee is addressed as "you".
72
Activities other than copying, distribution and modification are not
73
covered by this License; they are outside its scope. The act of

is covered only if its contents constitute a work based on the

Whether that is true depends on what the Program does.
80
79
1. You may copy and distribute verbatim copies of the Program's
81
source code as you receive it, in any medium, provided that you
82
conspicuously and appropriately publish on each copy an appropriate
83
copyright notice and disclaimer of warranty; keep intact all the

notices that refer to this License and to the absence of any

warranty; and give any other recipients of the Program a copy of

92
90
2. You may modify your copy or copies of the Program or any portion
93
of it, thus forming a work based on the Program, and copy and
94
distribute such modifications or work under the terms of Section 1
95
above, provided that you also meet all of these conditions:
97
a. You must cause the modified files to carry prominent notices
98
stating that you changed the files and the date of any change.
100
b. You must cause any work that you distribute or publish, that
101
in whole or in part contains or is derived from the Program
102
or any part thereof, to be licensed as a whole at no charge
103
to all third parties under the terms of this License.
105
c. If the modified program normally reads commands interactively
106
when run, you must cause it, when started running for such
107
interactive use in the most ordinary way, to print or display
108
an announcement including an appropriate copyright notice and
109
a notice that there is no warranty (or else, saying that you
110
provide a warranty) and that users may redistribute the
111
program under these conditions, and telling the user how to
112
view a copy of this License. (Exception: if the Program
113
itself is interactive but does not normally print such an
114
announcement, your work based on the Program is not required
115
to print an announcement.)
117
These requirements apply to the modified work as a whole. If
118
identifiable sections of that work are not derived from the
119
Program, and can be reasonably considered independent and separate
120
works in themselves, then this License, and its terms, do not
121
apply to those sections when you distribute them as separate
122
works. But when you distribute the same sections as part of a
123
whole which is a work based on the Program, the distribution of
124
the whole must be on the terms of this License, whose permissions
125
for other licensees extend to the entire whole, and thus to each
126
and every part regardless of who wrote it.
128
Thus, it is not the intent of this section to claim rights or
129
contest your rights to work written entirely by you; rather, the
130
intent is to exercise the right to control the distribution of
131
derivative or collective works based on the Program.
133
In addition, mere aggregation of another work not based on the
134
Program with the Program (or with a work based on the Program) on
135
a volume of a storage or distribution medium does not bring the
136
other work under the scope of this License.
91
of it, thus forming a work based on the Program, and copy and
92
distribute such modifications or work under the terms of Section 1
93
above, provided that you also meet all of these conditions:
95
a) You must cause the modified files to carry prominent notices
96
stating that you changed the files and the date of any change.
98
b) You must cause any work that you distribute or publish, that in
99
whole or in part contains or is derived from the Program or any
100
part thereof, to be licensed as a whole at no charge to all third
101
parties under the terms of this License.
103
c) If the modified program normally reads commands interactively
104
when run, you must cause it, when started running for such
105
interactive use in the most ordinary way, to print or display an
106
announcement including an appropriate copyright notice and a
107
notice that there is no warranty (or else, saying that you provide
108
a warranty) and that users may redistribute the program under
109
these conditions, and telling the user how to view a copy of this
110
License. (Exception: if the Program itself is interactive but
111
does not normally print such an announcement, your work based on
112
the Program is not required to print an announcement.)
114
These requirements apply to the modified work as a whole. If
115
identifiable sections of that work are not derived from the Program,
116
and can be reasonably considered independent and separate works in
117
themselves, then this License, and its terms, do not apply to those
118
sections when you distribute them as separate works. But when you
119
distribute the same sections as part of a whole which is a work based
120
on the Program, the distribution of the whole must be on the terms of
121
this License, whose permissions for other licensees extend to the
122
entire whole, and thus to each and every part regardless of who wrote it.
124
Thus, it is not the intent of this section to claim rights or contest
125
your rights to work written entirely by you; rather, the intent is to
126
exercise the right to control the distribution of derivative or
127
collective works based on the Program.
129
In addition, mere aggregation of another work not based on the Program
130
with the Program (or with a work based on the Program) on a volume of
131
a storage or distribution medium does not bring the other work under
132
the scope of this License.
138
134
3. You may copy and distribute the Program (or a work based on it,
139
under Section 2) in object code or executable form under the terms
140
of Sections 1 and 2 above provided that you also do one of the
143
a. Accompany it with the complete corresponding machine-readable
144
source code, which must be distributed under the terms of
145
Sections 1 and 2 above on a medium customarily used for
146
software interchange; or,
148
b. Accompany it with a written offer, valid for at least three
149
years, to give any third-party, for a charge no more than your
150
cost of physically performing source distribution, a complete
151
machine-readable copy of the corresponding source code, to be
152
distributed under the terms of Sections 1 and 2 above on a
153
medium customarily used for software interchange; or,
155
c. Accompany it with the information you received as to the offer
156
to distribute corresponding source code. (This alternative is
157
allowed only for noncommercial distribution and only if you
158
received the program in object code or executable form with
159
such an offer, in accord with Subsection b above.)
161
The source code for a work means the preferred form of the work for
162
making modifications to it. For an executable work, complete
163
source code means all the source code for all modules it contains,
164
plus any associated interface definition files, plus the scripts
165
used to control compilation and installation of the executable.
166
However, as a special exception, the source code distributed need
167
not include anything that is normally distributed (in either
168
source or binary form) with the major components (compiler,
169
kernel, and so on) of the operating system on which the executable
170
runs, unless that component itself accompanies the executable.
172
If distribution of executable or object code is made by offering
173
access to copy from a designated place, then offering equivalent
174
access to copy the source code from the same place counts as
175
distribution of the source code, even though third parties are not
176
compelled to copy the source along with the object code.
135
under Section 2) in object code or executable form under the terms of
136
Sections 1 and 2 above provided that you also do one of the following:
138
a) Accompany it with the complete corresponding machine-readable
139
source code, which must be distributed under the terms of Sections
140
1 and 2 above on a medium customarily used for software interchange; or,
142
b) Accompany it with a written offer, valid for at least three
143
years, to give any third party, for a charge no more than your
144
cost of physically performing source distribution, a complete
145
machine-readable copy of the corresponding source code, to be
146
distributed under the terms of Sections 1 and 2 above on a medium
147
customarily used for software interchange; or,
149
c) Accompany it with the information you received as to the offer
150
to distribute corresponding source code. (This alternative is
151
allowed only for noncommercial distribution and only if you
152
received the program in object code or executable form with such
153
an offer, in accord with Subsection b above.)
155
The source code for a work means the preferred form of the work for
156
making modifications to it. For an executable work, complete source
157
code means all the source code for all modules it contains, plus any
158
associated interface definition files, plus the scripts used to
159
control compilation and installation of the executable. However, as a
160
special exception, the source code distributed need not include
161
anything that is normally distributed (in either source or binary
162
form) with the major components (compiler, kernel, and so on) of the
163
operating system on which the executable runs, unless that component
164
itself accompanies the executable.
166
If distribution of executable or object code is made by offering
167
access to copy from a designated place, then offering equivalent
168
access to copy the source code from the same place counts as
169
distribution of the source code, even though third parties are not
170
compelled to copy the source along with the object code.
178
172
4. You may not copy, modify, sublicense, or distribute the Program
179
except as expressly provided under this License. Any attempt
180
otherwise to copy, modify, sublicense or distribute the Program is
181
void, and will automatically terminate your rights under this
182
License. However, parties who have received copies, or rights,
183
from you under this License will not have their licenses
184
terminated so long as such parties remain in full compliance.
173
except as expressly provided under this License. Any attempt
174
otherwise to copy, modify, sublicense or distribute the Program is
175
void, and will automatically terminate your rights under this License.
176
However, parties who have received copies, or rights, from you under
177
this License will not have their licenses terminated so long as such
178
parties remain in full compliance.
186
180
5. You are not required to accept this License, since you have not
187
signed it. However, nothing else grants you permission to modify
188
or distribute the Program or its derivative works. These actions
189
are prohibited by law if you do not accept this License.
190
Therefore, by modifying or distributing the Program (or any work
191
based on the Program), you indicate your acceptance of this
192
License to do so, and all its terms and conditions for copying,
193
distributing or modifying the Program or works based on it.

186
all its terms and conditions for copying, distributing or modifying
187
the Program or works based on it.
195
189
6. Each time you redistribute the Program (or any work based on the
196
Program), the recipient automatically receives a license from the
197
original licensor to copy, distribute or modify the Program
198
subject to these terms and conditions. You may not impose any

further restrictions on the recipients' exercise of the rights

granted herein. You are not responsible for enforcing compliance

194
You are not responsible for enforcing compliance by third parties to

204
infringement or for any other reason (not limited to patent
205
issues), conditions are imposed on you (whether by court order,
206
agreement or otherwise) that contradict the conditions of this
207
License, they do not excuse you from the conditions of this
208
License. If you cannot distribute so as to satisfy simultaneously
209
your obligations under this License and any other pertinent
210
obligations, then as a consequence you may not distribute the
211
Program at all. For example, if a patent license would not permit
212
royalty-free redistribution of the Program by all those who
213
receive copies directly or indirectly through you, then the only
214
way you could satisfy both it and this License would be to refrain
215
entirely from distribution of the Program.
217
If any portion of this section is held invalid or unenforceable
218
under any particular circumstance, the balance of the section is
219
intended to apply and the section as a whole is intended to apply
220
in other circumstances.
222
It is not the purpose of this section to induce you to infringe any
223
patents or other property right claims or to contest validity of
224
any such claims; this section has the sole purpose of protecting
225
the integrity of the free software distribution system, which is
226
implemented by public license practices. Many people have made
227
generous contributions to the wide range of software distributed
228
through that system in reliance on consistent application of that
229
system; it is up to the author/donor to decide if he or she is
230
willing to distribute software through any other system and a
231
licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed
234
to be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in
237
certain countries either by patents or by copyrighted interfaces,
238
the original copyright holder who places the Program under this
239
License may add an explicit geographical distribution limitation
240
excluding those countries, so that distribution is permitted only
241
in or among countries not thus excluded. In such case, this
242
License incorporates the limitation as if written in the body of
245
9. The Free Software Foundation may publish revised and/or new
246
versions of the General Public License from time to time. Such
247
new versions will be similar in spirit to the present version, but
248
may differ in detail to address new problems or concerns.
250
Each version is given a distinguishing version number. If the
251
Program specifies a version number of this License which applies
252
to it and "any later version", you have the option of following
253
the terms and conditions either of that version or of any later
254
version published by the Free Software Foundation. If the Program
255
does not specify a version number of this License, you may choose
256
any version ever published by the Free Software Foundation.
258
10. If you wish to incorporate parts of the Program into other free
259
programs whose distribution conditions are different, write to the
260
author to ask for permission. For software which is copyrighted
261
by the Free Software Foundation, write to the Free Software
262
Foundation; we sometimes make exceptions for this. Our decision
263
will be guided by the two goals of preserving the free status of
264
all derivatives of our free software and of promoting the sharing
265
and reuse of software generally.
268
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
269
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
270
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
271
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
272
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
273
NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
274
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
275
QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
276
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
277
SERVICING, REPAIR OR CORRECTION.
279
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
280
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
281
MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
282
LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
283
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
284
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
285
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
286
OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
287
OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

294
If you develop a new program, and you want it to be of the greatest
230
certain countries either by patents or by copyrighted interfaces, the
231
original copyright holder who places the Program under this License
232
may add an explicit geographical distribution limitation excluding
233
those countries, so that distribution is permitted only in or among
234
countries not thus excluded. In such case, this License incorporates
235
the limitation as if written in the body of this License.
237
9. The Free Software Foundation may publish revised and/or new versions
238
of the General Public License from time to time. Such new versions will
239
be similar in spirit to the present version, but may differ in detail to
240
address new problems or concerns.
242
Each version is given a distinguishing version number. If the Program
243
specifies a version number of this License which applies to it and "any
244
later version", you have the option of following the terms and conditions
245
either of that version or of any later version published by the Free
246
Software Foundation. If the Program does not specify a version number of
247
this License, you may choose any version ever published by the Free Software
250
10. If you wish to incorporate parts of the Program into other free
251
programs whose distribution conditions are different, write to the author
252
to ask for permission. For software which is copyrighted by the Free
253
Software Foundation, write to the Free Software Foundation; we sometimes
254
make exceptions for this. Our decision will be guided by the two goals
255
of preserving the free status of all derivatives of our free software and
256
of promoting the sharing and reuse of software generally.
260
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
262
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
266
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
267
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268
REPAIR OR CORRECTION.
270
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278
POSSIBILITY OF SUCH DAMAGES.

282
How to Apply These Terms to Your New Programs
284
If you develop a new program, and you want it to be of the greatest
295
285
possible use to the public, the best way to achieve this is to make it
296
free software which everyone can redistribute and change under these
299
To do so, attach the following notices to the program. It is safest to
300
attach them to the start of each source file to most effectively convey
301
the exclusion of warranty; and each file should have at least the
302
"copyright" line and a pointer to where the full notice is found.
304
ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.

310
Also add information on how to contact you by electronic and paper mail.
323
312
If the program is interactive, make it output a short notice like this
324
313
when it starts in an interactive mode:
326

You should also get your employer (if you work as a programmer) or your
338
326
school, if any, to sign a "copyright disclaimer" for the program, if
339
327
necessary. Here is a sample; alter the names:

This General Public License does not permit incorporating your program
348
into proprietary programs. If your program is a subroutine library,
349
you may consider it more useful to permit linking proprietary
350
applications with the library. If this is what you want to do, use the
351
GNU Library General Public License instead of this License.
