24e75b45 11 Preamble
a687059c
LW
12
13 The license agreements of most software companies try to keep users
14at the mercy of those companies. By contrast, our General Public
15License is intended to guarantee your freedom to share and change free
16software--to make sure the software is free for all its users. The
17General Public License applies to the Free Software Foundation's
18software and to any other program whose authors commit to using it.
19You can use it for your programs, too.
20
21 When we speak of free software, we are referring to freedom, not
22price. Specifically, the General Public License is designed to make
23sure that you have the freedom to give away or sell copies of free
24software, that you receive source code or can get it if you want it,
25that you can change the software or use pieces of it in new free
26programs; and that you know you can do these things.
27
28 To protect your rights, we need to make restrictions that forbid
29anyone to deny you these rights or to ask you to surrender the rights.
30These restrictions translate to certain responsibilities for you if you
31distribute copies of the software, or if you modify it.
32
33 For example, if you distribute copies of a such a program, whether
34gratis or for a fee, you must give the recipients all the rights that
35you have. You must make sure that they, too, receive or can get the
36source code. And you must tell them their 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,
40distribute and/or modify the software.
41
42 Also, for each author's protection and ours, we want to make certain
43that everyone understands that there is no warranty for this free
44software. If the software is modified by someone else and passed on, we
45want its recipients to know that what they have is not the original, so
46that any problems introduced by others will not reflect on the original
47authors' reputations.
48
49 The precise terms and conditions for copying, distribution and
50modification follow.

24e75b45 52 GNU GENERAL PUBLIC LICENSE

53 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
54
55 0. This License Agreement applies to any program or other work which
56contains a notice placed by the copyright holder saying it may be
57distributed under the terms of this General Public License. The
58"Program", below, refers to any such program or work, and a "work based
59on the Program" means either the Program or any work containing the
60Program or a portion of it, either verbatim or with modifications. Each
61licensee is addressed as "you".
62
63 1. You may copy and distribute verbatim copies of the Program's source
64code as you receive it, in any medium, provided that you conspicuously and
65appropriately publish on each copy an appropriate copyright notice and
66disclaimer of warranty; keep intact all the notices that refer to this
67General Public License and to the absence of any warranty; and give any
68other recipients of the Program a copy of this General Public License
69along with the Program. You may charge a fee for the physical act of
70transferring a copy.
71
72 2. You may modify your copy or copies of the Program or any portion of
73it, and copy and distribute such modifications under the terms of Paragraph
741 above, provided that you also do the following:
75
76 a) cause the modified files to carry prominent notices stating that
77 you changed the files and the date of any change; and
78
79 b) cause the whole of any work that you distribute or publish, that
80 in whole or in part contains the Program or any part thereof, either
81 with or without modifications, to be licensed at no charge to all
82 third parties under the terms of this General Public License (except
83 that you may choose to grant warranty protection to some or all
84 third parties, at your option).
85
86 c) If the modified program normally reads commands interactively when
87 run, you must cause it, when started running for such interactive use
88 in the simplest and most usual way, to print or display an
89 announcement including an appropriate copyright notice and a notice
90 that there is no warranty (or else, saying that you provide a
91 warranty) and that users may redistribute the program under these
92 conditions, and telling the user how to view a copy of this General
93 Public License.
94
95 d) You may charge a fee for the physical act of transferring a
96 copy, and you may at your option offer warranty protection in
97 exchange for a fee.
98
99Mere aggregation of another independent work with the Program (or its
100derivative) on a volume of a storage or distribution medium does not bring
101the other work under the scope of these terms.
102\f
103 3. You may copy and distribute the Program (or a portion or derivative of
104it, under Paragraph 2) in object code or executable form under the terms of
105Paragraphs 1 and 2 above provided that you also do one of the following:
106
107 a) accompany it with the complete corresponding machine-readable
108 source code, which must be distributed under the terms of
109 Paragraphs 1 and 2 above; or,
110
111 b) accompany it with a written offer, valid for at least three
112 years, to give any third party free (except for a nominal charge
113 for the cost of distribution) a complete machine-readable copy of the
114 corresponding source code, to be distributed under the terms of
115 Paragraphs 1 and 2 above; or,
116
117 c) accompany it with the information you received as to where the
118 corresponding source code may be obtained. (This alternative is
119 allowed only for noncommercial distribution and only if you
120 received the program in object code or executable form alone.)
121
122Source code for a work means the preferred form of the work for making
123modifications to it. For an executable file, complete source code means
124all the source code for all modules it contains; but, as a special
125exception, it need not include source code for modules which are standard
126libraries that accompany the operating system on which the executable
127file runs, or for standard header files or definitions files that
128accompany that operating system.
129
130 4. You may not copy, modify, sublicense, distribute or transfer the
131Program except as expressly provided under this General Public License.
132Any attempt otherwise to copy, modify, sublicense, distribute or transfer
133the Program is void, and will automatically terminate your rights to use
134the Program under this License. However, parties who have received
135copies, or rights to use copies, from you under this General Public
136License will not have their licenses terminated so long as such parties
137remain in full compliance.
138
139 5. By copying, distributing or modifying the Program (or any work based
140on the Program) you indicate your acceptance of this license to do so,
141and all its terms and conditions.
142
143 6. Each time you redistribute the Program (or any work based on the
144Program), the recipient automatically receives a license from the original
145licensor to copy, distribute or modify the Program subject to these
146terms and conditions. You may not impose any further restrictions on the
147recipients' exercise of the rights granted herein.
148\f
149 7. The Free Software Foundation may publish revised and/or new versions
150of the General Public License from time to time. Such new versions will
151be similar in spirit to the present version, but may differ in detail to
152address new problems or concerns.
153
154Each version is given a distinguishing version number. If the Program
155specifies a version number of the license which applies to it and "any
156later version", you have the option of following the terms and conditions
157either of that version or of any later version published by the Free
158Software Foundation. If the Program does not specify a version number of
159the license, you may choose any version ever published by the Free Software
160Foundation.
161
162 8. If you wish to incorporate parts of the Program into other free
163programs whose distribution conditions are different, write to the author
164to ask for permission. For software which is copyrighted by the Free
165Software Foundation, write to the Free Software Foundation; we sometimes
166make exceptions for this. Our decision will be guided by the two goals
167of preserving the free status of all derivatives of our free software and
168of promoting the sharing and reuse of software generally.
169
24e75b45 170 NO WARRANTY
a687059c
LW
171
172 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
173FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
174OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
175PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
176OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
177MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
178TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
179PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
180REPAIR OR CORRECTION.
181
182 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
183WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
184REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
185INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
186OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
187TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
188YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
189PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
190POSSIBILITY OF SUCH DAMAGES.
191

24e75b45 194 Appendix: How to Apply These Terms to Your New Programs
a687059c
LW
195
196 If you develop a new program, and you want it to be of the greatest
197possible use to humanity, the best way to achieve this is to make it
198free software which everyone can redistribute and change under these
199terms.
200
201 To do so, attach the following notices to the program. It is safest to
202attach them to the start of each source file to most effectively convey
203the exclusion of warranty; and each file should have at least the
204"copyright" line and a pointer to where the full notice is found.
205
206 <one line to give the program's name and a brief idea of what it does.>
207 Copyright (C) 19yy <name of author>
208
209 This program is free software; you can redistribute it and/or modify
210 it under the terms of the GNU General Public License as published by
211 the Free Software Foundation; either version 1, or (at your option)
212 any later version.
213
214 This program is distributed in the hope that it will be useful,
215 but WITHOUT ANY WARRANTY; without even the implied warranty of
216 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
217 GNU General Public License for more details.
218
219 You should have received a copy of the GNU General Public License
24e75b45
NC
220 along with this program; if not, write to the Free Software
221 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA
222
a687059c
LW
223
224Also add information on how to contact you by electronic and paper mail.
225
226If the program is interactive, make it output a short notice like this
227when it starts in an interactive mode:
228
229 Gnomovision version 69, Copyright (C) 19xx name of author
24e75b45 230 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
a687059c 231 This is free software, and you are welcome to redistribute it
24e75b45 232 under certain conditions; type `show c' for details.
a687059c 233
24e75b45 234The hypothetical commands `show w' and `show c' should show the
a687059c 235appropriate parts of the General Public License. Of course, the
24e75b45 236commands you use may be called something other than `show w' and `show
a687059c
LW
237c'; they could even be mouse-clicks or menu items--whatever suits your
238program.
239
240You should also get your employer (if you work as a programmer) or your
241school, if any, to sign a "copyright disclaimer" for the program, if
242necessary. Here a sample; alter the names:
243
244 Yoyodyne, Inc., hereby disclaims all copyright interest in the
24e75b45 245 program `Gnomovision' (a program to direct compilers to make passes
a687059c

246 at assemblers) written by James Hacker.
