9 GNU GENERAL PUBLIC LICENSE
10 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
11
12 0. This License applies to any program or other work which contains
13 a notice placed by the copyright holder saying it may be distributed
14 under the terms of this General Public License. The "Program", below,
15 refers to any such program or work, and a "work based on the Program"
16 means either the Program or any derivative work under copyright law:
17 that is to say, a work containing the Program or a portion of it,
18 either verbatim or with modifications and/or translated into another
19 language. (Hereinafter, translation is included without limitation in
20 the term "modification".) Each licensee is addressed as "you".
21
22 Activities other than copying, distribution and modification are not
23 covered by this License; they are outside its scope. The act of
24 running the Program is not restricted, and the output from the Program
25 is covered only if its contents constitute a work based on the
26 Program (independent of having been made by running the Program).
27 Whether that is true depends on what the Program does.
28
29 1. You may copy and distribute verbatim copies of the Program's
30 source code as you receive it, in any medium, provided that you
31 conspicuously and appropriately publish on each copy an appropriate
32 copyright notice and disclaimer of warranty; keep intact all the
33 notices that refer to this License and to the absence of any warranty;
34 and give any other recipients of the Program a copy of this License
35 along with the Program.
36
37 You may charge a fee for the physical act of transferring a copy, and
38 you may at your option offer warranty protection in exchange for a fee.
39
40 2. You may modify your copy or copies of the Program or any portion
41 of it, thus forming a work based on the Program, and copy and
42 distribute such modifications or work under the terms of Section 1
43 above, provided that you also meet all of these conditions:
44
45 a) You must cause the modified files to carry prominent notices
46 stating that you changed the files and the date of any change.
47
48 b) You must cause any work that you distribute or publish, that in
49 whole or in part contains or is derived from the Program or any
50 part thereof, to be licensed as a whole at no charge to all third
51 parties under the terms of this License.
52
53 c) If the modified program normally reads commands interactively
54 when run, you must cause it, when started running for such
55 interactive use in the most ordinary way, to print or display an
56 announcement including an appropriate copyright notice and a
57 notice that there is no warranty (or else, saying that you provide
58 a warranty) and that users may redistribute the program under
59 these conditions, and telling the user how to view a copy of this
60 License. (Exception: if the Program itself is interactive but
61 does not normally print such an announcement, your work based on
62 the Program is not required to print an announcement.)
63
64 These requirements apply to the modified work as a whole. If
65 identifiable sections of that work are not derived from the Program,
66 and can be reasonably considered independent and separate works in
67 themselves, then this License, and its terms, do not apply to those
68 sections when you distribute them as separate works. But when you
69 distribute the same sections as part of a whole which is a work based
70 on the Program, the distribution of the whole must be on the terms of
71 this License, whose permissions for other licensees extend to the
72 entire whole, and thus to each and every part regardless of who wrote it.
73
74 Thus, it is not the intent of this section to claim rights or contest
75 your rights to work written entirely by you; rather, the intent is to
76 exercise the right to control the distribution of derivative or
77 collective works based on the Program.
78
79 In addition, mere aggregation of another work not based on the Program
80 with the Program (or with a work based on the Program) on a volume of
81 a storage or distribution medium does not bring the other work under
82 the scope of this License.
83
84 3. You may copy and distribute the Program (or a work based on it,
85 under Section 2) in object code or executable form under the terms of
86 Sections 1 and 2 above provided that you also do one of the following:
87
88 a) Accompany it with the complete corresponding machine-readable
89 source code, which must be distributed under the terms of Sections
90 1 and 2 above on a medium customarily used for software interchange; or,
91
92 b) Accompany it with a written offer, valid for at least three
93 years, to give any third party, for a charge no more than your
94 cost of physically performing source distribution, a complete
95 machine-readable copy of the corresponding source code, to be
96 distributed under the terms of Sections 1 and 2 above on a medium
97 customarily used for software interchange; or,
98
99 c) Accompany it with the information you received as to the offer
100 to distribute corresponding source code. (This alternative is
101 allowed only for noncommercial distribution and only if you
102 received the program in object code or executable form with such
103 an offer, in accord with Subsection b above.)
104
105 The source code for a work means the preferred form of the work for
106 making modifications to it. For an executable work, complete source
107 code means all the source code for all modules it contains, plus any
108 associated interface definition files, plus the scripts used to
109 control compilation and installation of the executable. However, as a
110 special exception, the source code distributed need not include
111 anything that is normally distributed (in either source or binary
112 form) with the major components (compiler, kernel, and so on) of the
113 operating system on which the executable runs, unless that component
114 itself accompanies the executable.
115
116 If distribution of executable or object code is made by offering
117 access to copy from a designated place, then offering equivalent
118 access to copy the source code from the same place counts as
119 distribution of the source code, even though third parties are not
120 compelled to copy the source along with the object code.
121
122 4. You may not copy, modify, sublicense, or distribute the Program
123 except as expressly provided under this License. Any attempt
124 otherwise to copy, modify, sublicense or distribute the Program is
125 void, and will automatically terminate your rights under this License.
126 However, parties who have received copies, or rights, from you under
127 this License will not have their licenses terminated so long as such
128 parties remain in full compliance.
129
130 5. You are not required to accept this License, since you have not
131 signed it. However, nothing else grants you permission to modify or
132 distribute the Program or its derivative works. These actions are
133 prohibited by law if you do not accept this License. Therefore, by
134 modifying or distributing the Program (or any work based on the
135 Program), you indicate your acceptance of this License to do so, and
136 all its terms and conditions for copying, distributing or modifying
137 the Program or works based on it.
138
139 6. Each time you redistribute the Program (or any work based on the
140 Program), the recipient automatically receives a license from the
141 original licensor to copy, distribute or modify the Program subject to
142 these terms and conditions. You may not impose any further
143 restrictions on the recipients' exercise of the rights granted herein.
144 You are not responsible for enforcing compliance by third parties to
145 this License.
146
147 7. If, as a consequence of a court judgment or allegation of patent
148 infringement or for any other reason (not limited to patent issues),
149 conditions are imposed on you (whether by court order, agreement or
150 otherwise) that contradict the conditions of this License, they do not
151 excuse you from the conditions of this License. If you cannot
152 distribute so as to satisfy simultaneously your obligations under this
153 License and any other pertinent obligations, then as a consequence you
154 may not distribute the Program at all. For example, if a patent
155 license would not permit royalty-free redistribution of the Program by
156 all those who receive copies directly or indirectly through you, then
157 the only way you could satisfy both it and this License would be to
158 refrain entirely from distribution of the Program.
159
160 If any portion of this section is held invalid or unenforceable under
161 any particular circumstance, the balance of the section is intended to
162 apply and the section as a whole is intended to apply in other
163 circumstances.
164
165 It is not the purpose of this section to induce you to infringe any
166 patents or other property right claims or to contest validity of any
167 such claims; this section has the sole purpose of protecting the
168 integrity of the free software distribution system, which is
169 implemented by public license practices. Many people have made
170 generous contributions to the wide range of software distributed
171 through that system in reliance on consistent application of that
172 system; it is up to the author/donor to decide if he or she is willing
173 to distribute software through any other system and a licensee cannot
174 impose that choice.
175
176 This section is intended to make thoroughly clear what is believed to
177 be a consequence of the rest of this License.
178
179 8. If the distribution and/or use of the Program is restricted in
180 certain countries either by patents or by copyrighted interfaces, the
181 original copyright holder who places the Program under this License
182 may add an explicit geographical distribution limitation excluding
183 those countries, so that distribution is permitted only in or among
184 countries not thus excluded. In such case, this License incorporates
185 the limitation as if written in the body of this License.
186
187 9. The Free Software Foundation may publish revised and/or new versions
188 of the General Public License from time to time. Such new versions will
189 be similar in spirit to the present version, but may differ in detail to
190 address new problems or concerns.
191
192 Each version is given a distinguishing version number. If the Program
193 specifies a version number of this License which applies to it and "any
194 later version", you have the option of following the terms and conditions
195 either of that version or of any later version published by the Free
196 Software Foundation. If the Program does not specify a version number of
197 this License, you may choose any version ever published by the Free Software
198 Foundation.
199
200 10. If you wish to incorporate parts of the Program into other free
201 programs whose distribution conditions are different, write to the author
202 to ask for permission. For software which is copyrighted by the Free
203 Software Foundation, write to the Free Software Foundation; we sometimes
204 make exceptions for this. Our decision will be guided by the two goals
205 of preserving the free status of all derivatives of our free software and
206 of promoting the sharing and reuse of software generally.
207
208 NO WARRANTY
209
210 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
211 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
212 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
213 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
214 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
215 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
216 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
217 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
218 REPAIR OR CORRECTION.
219
220 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
221 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
222 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
223 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
224 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
225 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
226 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
227 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
228 POSSIBILITY OF SUCH DAMAGES.
