12 The license agreements of most software companies try to keep users

15software--to make sure the software is free for all its users. This
16General Public License applies to most of the Free Software
17Foundation's software and to any other program whose authors commit to
18using it. (Some other Free Software Foundation software is covered by
19the GNU Library General Public License instead.) You can apply it to
20your programs, too.

22 When we speak of free software, we are referring to freedom, not
21price. Specifically, the General Public License is designed to make
22sure that you have the freedom to give away or sell copies of free
23software, that you receive source code or can get it if you want it,
24that you can change the software or use pieces of it in new free
25programs; and that you know you can do these things.

24have the freedom to distribute copies of free software (and charge for
25this service if you wish), that you receive source code or can get it
26if you want it, that you can change the software or use pieces of it
27in 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
28anyone to deny you these rights or to ask you to surrender the rights.
29These restrictions translate to certain responsibilities for you if you
30distribute copies of the software, or if you modify it.

38rights.

37 We protect your rights with two steps: (1) copyright the software, and
38(2) offer you this license which gives you legal permission to copy,
39distribute and/or modify the software.
40
41 Also, for each author's protection and ours, we want to make certain
42that everyone understands that there is no warranty for this free
43software. If the software is modified by someone else and passed on, we
44want its recipients to know that what they have is not the original, so
45that any problems introduced by others will not reflect on the original
46authors' reputations.

51 Finally, any free program is threatened constantly by software
52patents. We wish to avoid the danger that redistributors of a free
53program will individually obtain patent licenses, in effect making the
54program proprietary. To prevent this, we have made it clear that any
55patent must be licensed for everyone's free use or not licensed at all.

52 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
53
61 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
62
54 0. This License Agreement applies to any program or other work which
55contains a notice placed by the copyright holder saying it may be
56distributed under the terms of this General Public License. The
57"Program", below, refers to any such program or work, and a "work based
58on the Program" means either the Program or any work containing the
59Program or a portion of it, either verbatim or with modifications. Each
60licensee is addressed as "you".
63 0. This License applies to any program or other work which contains
64a notice placed by the copyright holder saying it may be distributed
65under the terms of this General Public License. The "Program", below,
66refers to any such program or work, and a "work based on the Program"
67means either the Program or any derivative work under copyright law:
68that is to say, a work containing the Program or a portion of it,
69either verbatim or with modifications and/or translated into another
70language. (Hereinafter, translation is included without limitation in
71the term "modification".) Each licensee is addressed as "you".
61
72
62 1. You may copy and distribute verbatim copies of the Program's source
63code as you receive it, in any medium, provided that you conspicuously and
64appropriately publish on each copy an appropriate copyright notice and
65disclaimer of warranty; keep intact all the notices that refer to this
66General Public License and to the absence of any warranty; and give any
67other recipients of the Program a copy of this General Public License
68along with the Program. You may charge a fee for the physical act of
69transferring a copy.
73Activities other than copying, distribution and modification are not
74covered by this License; they are outside its scope. The act of
75running the Program is not restricted, and the output from the Program
76is covered only if its contents constitute a work based on the
77Program (independent of having been made by running the Program).
78Whether that is true depends on what the Program does.
70
79
71 2. You may modify your copy or copies of the Program or any portion of
72it, and copy and distribute such modifications under the terms of Paragraph
731 above, provided that you also do the following:
80 1. You may copy and distribute verbatim copies of the Program's
81source code as you receive it, in any medium, provided that you
82conspicuously and appropriately publish on each copy an appropriate
83copyright notice and disclaimer of warranty; keep intact all the
84notices that refer to this License and to the absence of any warranty;
85and give any other recipients of the Program a copy of this License
86along with the Program.
74
87
75 a) cause the modified files to carry prominent notices stating that
76 you changed the files and the date of any change; and
88You may charge a fee for the physical act of transferring a copy, and
89you may at your option offer warranty protection in exchange for a fee.
77
90
78 b) cause the whole of any work that you distribute or publish, that
79 in whole or in part contains the Program or any part thereof, either
80 with or without modifications, to be licensed at no charge to all
81 third parties under the terms of this General Public License (except
82 that you may choose to grant warranty protection to some or all
83 third parties, at your option).
91 2. You may modify your copy or copies of the Program or any portion
92of it, thus forming a work based on the Program, and copy and
93distribute such modifications or work under the terms of Section 1
94above, provided that you also meet all of these conditions:
84
95
85 c) If the modified program normally reads commands interactively when
86 run, you must cause it, when started running for such interactive use
87 in the simplest and most usual way, to print or display an
88 announcement including an appropriate copyright notice and a notice
89 that there is no warranty (or else, saying that you provide a
90 warranty) and that users may redistribute the program under these
91 conditions, and telling the user how to view a copy of this General
92 Public License.
96 a) You must cause the modified files to carry prominent notices
97 stating that you changed the files and the date of any change.
93
98
94 d) You may charge a fee for the physical act of transferring a
95 copy, and you may at your option offer warranty protection in
96 exchange for a fee.
99 b) You must cause any work that you distribute or publish, that in
100 whole or in part contains or is derived from the Program or any
101 part thereof, to be licensed as a whole at no charge to all third
102 parties under the terms of this License.
97
103
98Mere aggregation of another independent work with the Program (or its
99derivative) on a volume of a storage or distribution medium does not bring
100the other work under the scope of these terms.
104 c) If the modified program normally reads commands interactively
105 when run, you must cause it, when started running for such
106 interactive use in the most ordinary way, to print or display an
107 announcement including an appropriate copyright notice and a
108 notice that there is no warranty (or else, saying that you provide
109 a warranty) and that users may redistribute the program under
110 these conditions, and telling the user how to view a copy of this
111 License. (Exception: if the Program itself is interactive but
112 does not normally print such an announcement, your work based on
113 the Program is not required to print an announcement.)
101
114
102 3. You may copy and distribute the Program (or a portion or derivative of
103it, under Paragraph 2) in object code or executable form under the terms of
104Paragraphs 1 and 2 above provided that you also do one of the following:
115These requirements apply to the modified work as a whole. If
116identifiable sections of that work are not derived from the Program,
117and can be reasonably considered independent and separate works in
118themselves, then this License, and its terms, do not apply to those
119sections when you distribute them as separate works. But when you
120distribute the same sections as part of a whole which is a work based
121on the Program, the distribution of the whole must be on the terms of
122this License, whose permissions for other licensees extend to the
123entire whole, and thus to each and every part regardless of who wrote it.
105
124
106 a) accompany it with the complete corresponding machine-readable
107 source code, which must be distributed under the terms of
108 Paragraphs 1 and 2 above; or,
125Thus, it is not the intent of this section to claim rights or contest
126your rights to work written entirely by you; rather, the intent is to
127exercise the right to control the distribution of derivative or
128collective works based on the Program.
109
129
110 b) accompany it with a written offer, valid for at least three
111 years, to give any third party free (except for a nominal charge
112 for the cost of distribution) a complete machine-readable copy of the
113 corresponding source code, to be distributed under the terms of
114 Paragraphs 1 and 2 above; or,
130In addition, mere aggregation of another work not based on the Program
131with the Program (or with a work based on the Program) on a volume of
132a storage or distribution medium does not bring the other work under
133the scope of this License.
115
134
116 c) accompany it with the information you received as to where the
117 corresponding source code may be obtained. (This alternative is
135 3. You may copy and distribute the Program (or a work based on it,
136under Section 2) in object code or executable form under the terms of
137Sections 1 and 2 above provided that you also do one of the following:
138
139 a) Accompany it with the complete corresponding machine-readable
140 source code, which must be distributed under the terms of Sections
141 1 and 2 above on a medium customarily used for software interchange; or,
142
143 b) Accompany it with a written offer, valid for at least three
144 years, to give any third party, for a charge no more than your
145 cost of physically performing source distribution, a complete
146 machine-readable copy of the corresponding source code, to be
147 distributed under the terms of Sections 1 and 2 above on a medium
148 customarily used for software interchange; or,
149
150 c) Accompany it with the information you received as to the offer
151 to distribute corresponding source code. (This alternative is
118 allowed only for noncommercial distribution and only if you
152 allowed only for noncommercial distribution and only if you
119 received the program in object code or executable form alone.)
153 received the program in object code or executable form with such
154 an offer, in accord with Subsection b above.)
120
155
121Source code for a work means the preferred form of the work for making
122modifications to it. For an executable file, complete source code means
123all the source code for all modules it contains; but, as a special
124exception, it need not include source code for modules which are standard
125libraries that accompany the operating system on which the executable
126file runs, or for standard header files or definitions files that
127accompany that operating system.
156The source code for a work means the preferred form of the work for
157making modifications to it. For an executable work, complete source
158code means all the source code for all modules it contains, plus any
159associated interface definition files, plus the scripts used to
160control compilation and installation of the executable. However, as a
161special exception, the source code distributed need not include
162anything that is normally distributed (in either source or binary
163form) with the major components (compiler, kernel, and so on) of the
164operating system on which the executable runs, unless that component
165itself accompanies the executable.
128
166
129 4. You may not copy, modify, sublicense, distribute or transfer the
130Program except as expressly provided under this General Public License.
131Any attempt otherwise to copy, modify, sublicense, distribute or transfer
132the Program is void, and will automatically terminate your rights to use
133the Program under this License. However, parties who have received
134copies, or rights to use copies, from you under this General Public
135License will not have their licenses terminated so long as such parties
136remain in full compliance.
167If distribution of executable or object code is made by offering
168access to copy from a designated place, then offering equivalent
169access to copy the source code from the same place counts as
170distribution of the source code, even though third parties are not
171compelled to copy the source along with the object code.
172
173 4. You may not copy, modify, sublicense, or distribute the Program
174except as expressly provided under this License. Any attempt
175otherwise to copy, modify, sublicense or distribute the Program is
176void, and will automatically terminate your rights under this License.
177However, parties who have received copies, or rights, from you under
178this License will not have their licenses terminated so long as such
179parties remain in full compliance.
137
180
138 5. By copying, distributing or modifying the Program (or any work based
139on the Program) you indicate your acceptance of this license to do so,
140and all its terms and conditions.
181 5. You are not required to accept this License, since you have not
182signed it. However, nothing else grants you permission to modify or
183distribute the Program or its derivative works. These actions are
184prohibited by law if you do not accept this License. Therefore, by
185modifying or distributing the Program (or any work based on the
186Program), you indicate your acceptance of this License to do so, and
187all its terms and conditions for copying, distributing or modifying
188the Program or works based on it.
141
142 6. Each time you redistribute the Program (or any work based on the
189
190 6. Each time you redistribute the Program (or any work based on the
143Program), the recipient automatically receives a license from the original
144licensor to copy, distribute or modify the Program subject to these
145terms and conditions. You may not impose any further restrictions on the
146recipients' exercise of the rights granted herein.
191Program), the recipient automatically receives a license from the
192original licensor to copy, distribute or modify the Program subject to
193these terms and conditions. You may not impose any further
194restrictions on the recipients' exercise of the rights granted herein.
195You are not responsible for enforcing compliance by third parties to
196this License.
197
198 7. If, as a consequence of a court judgment or allegation of patent
199infringement or for any other reason (not limited to patent issues),
200conditions are imposed on you (whether by court order, agreement or
201otherwise) that contradict the conditions of this License, they do not
202excuse you from the conditions of this License. If you cannot
203distribute so as to satisfy simultaneously your obligations under this
204License and any other pertinent obligations, then as a consequence you
205may not distribute the Program at all. For example, if a patent
206license would not permit royalty-free redistribution of the Program by
207all those who receive copies directly or indirectly through you, then
208the only way you could satisfy both it and this License would be to
209refrain entirely from distribution of the Program.
210
211If any portion of this section is held invalid or unenforceable under
212any particular circumstance, the balance of the section is intended to
213apply and the section as a whole is intended to apply in other
214circumstances.
215
216It is not the purpose of this section to induce you to infringe any
217patents or other property right claims or to contest validity of any
218such claims; this section has the sole purpose of protecting the
219integrity of the free software distribution system, which is
220implemented by public license practices. Many people have made
221generous contributions to the wide range of software distributed
222through that system in reliance on consistent application of that
223system; it is up to the author/donor to decide if he or she is willing
224to distribute software through any other system and a licensee cannot
225impose that choice.
226
227This section is intended to make thoroughly clear what is believed to
228be a consequence of the rest of this License.
147
229
148 7. The Free Software Foundation may publish revised and/or new versions
230 8. If the distribution and/or use of the Program is restricted in
231certain countries either by patents or by copyrighted interfaces, the
232original copyright holder who places the Program under this License
233may add an explicit geographical distribution limitation excluding
234those countries, so that distribution is permitted only in or among
235countries not thus excluded. In such case, this License incorporates
236the limitation as if written in the body of this License.
237
238 9. The Free Software Foundation may publish revised and/or new versions
149of the General Public License from time to time. Such new versions will
150be similar in spirit to the present version, but may differ in detail to
151address new problems or concerns.

243Each version is given a distinguishing version number. If the Program
154specifies a version number of the license which applies to it and "any
244specifies a version number of this License which applies to it and "any
155later version", you have the option of following the terms and conditions
156either of that version or of any later version published by the Free

245later version", you have the option of following the terms and conditions
246either of that version or of any later version published by the Free
247Software Foundation. If the Program does not specify a version number of

162programs whose distribution conditions are different, write to the author
163to ask for permission. For software which is copyrighted by the Free

165make exceptions for this. Our decision will be guided by the two goals
