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

10
11  The licenses for most software are designed to take away your
12freedom to share and change it.  By contrast, the GNU General Public
13License is intended to guarantee your freedom to share and change free
14software--to make sure the software is free for all its users.  This
15General Public License applies to most of the Free Software
16Foundation's software and to any other program whose authors commit to
17using it.  (Some other Free Software Foundation software is covered by
18the GNU Library General Public License instead.)  You can apply it to
19your programs, too.
20
21  When we speak of free software, we are referring to freedom, not
22price.  Our General Public Licenses are designed to make sure that you
23have the freedom to distribute copies of free software (and charge for
24this service if you wish), that you receive source code or can get it
25if you want it, that you can change the software or use pieces of it
26in new free programs; 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 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 show them these terms so they know their
37rights.
38
39  We protect your rights with two steps: (1) copyright the software, and
40(2) offer you this license which gives you legal permission to copy,
41distribute and/or modify the software.
42
43  Also, for each author's protection and ours, we want to make certain
44that everyone understands that there is no warranty for this free
45software.  If the software is modified by someone else and passed on, we
46want its recipients to know that what they have is not the original, so
47that any problems introduced by others will not reflect on the original
48authors' reputations.
49
50  Finally, any free program is threatened constantly by software
51patents.  We wish to avoid the danger that redistributors of a free
52program will individually obtain patent licenses, in effect making the
53program proprietary.  To prevent this, we have made it clear that any
54patent must be licensed for everyone's free use or not licensed at all.
55
56  The precise terms and conditions for copying, distribution and
57modification follow.
58                    GNU GENERAL PUBLIC LICENSE
59   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
60
61  0. This License applies to any program or other work which contains
62a notice placed by the copyright holder saying it may be distributed
63under the terms of this General Public License.  The "Program", below,
64refers to any such program or work, and a "work based on the Program"
65means either the Program or any derivative work under copyright law:
66that is to say, a work containing the Program or a portion of it,
67either verbatim or with modifications and/or translated into another
68language.  (Hereinafter, translation is included without limitation in
69the term "modification".)  Each licensee is addressed as "you".
70
71Activities other than copying, distribution and modification are not
72covered by this License; they are outside its scope.  The act of
73running the Program is not restricted, and the output from the Program
74is covered only if its contents constitute a work based on the
75Program (independent of having been made by running the Program).
76Whether that is true depends on what the Program does.
77
78  1. You may copy and distribute verbatim copies of the Program's
79source code as you receive it, in any medium, provided that you
80conspicuously and appropriately publish on each copy an appropriate
81copyright notice and disclaimer of warranty; keep intact all the
82notices that refer to this License and to the absence of any warranty;
83and give any other recipients of the Program a copy of this License
84along with the Program.
85
86You may charge a fee for the physical act of transferring a copy, and
87you 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
90of it, thus forming a work based on the Program, and copy and
91distribute such modifications or work under the terms of Section 1
92above, 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.)
112These requirements apply to the modified work as a whole.  If
113identifiable sections of that work are not derived from the Program,
114and can be reasonably considered independent and separate works in
115themselves, then this License, and its terms, do not apply to those
116sections when you distribute them as separate works.  But when you
117distribute the same sections as part of a whole which is a work based
118on the Program, the distribution of the whole must be on the terms of
119this License, whose permissions for other licensees extend to the
120entire whole, and thus to each and every part regardless of who wrote it.
121
122Thus, it is not the intent of this section to claim rights or contest
123your rights to work written entirely by you; rather, the intent is to
124exercise the right to control the distribution of derivative or
125collective works based on the Program.
126
127In addition, mere aggregation of another work not based on the Program
128with the Program (or with a work based on the Program) on a volume of
129a storage or distribution medium does not bring the other work under
130the scope of this License.
131
132  3. You may copy and distribute the Program (or a work based on it,
133under Section 2) in object code or executable form under the terms of
134Sections 1 and 2 above provided that you also do one of the following:
135
136    a) Accompany it with the complete corresponding machine-readable
137    source code, which must be distributed under the terms of Sections
138    1 and 2 above on a medium customarily used for software interchange; or,
139
140    b) Accompany it with a written offer, valid for at least three
141    years, to give any third party, for a charge no more than your
142    cost of physically performing source distribution, a complete
143    machine-readable copy of the corresponding source code, to be
144    distributed under the terms of Sections 1 and 2 above on a medium
145    customarily used for software interchange; or,
146
147    c) Accompany it with the information you received as to the offer
148    to distribute corresponding source code.  (This alternative is
149    allowed only for noncommercial distribution and only if you
150    received the program in object code or executable form with such
151    an offer, in accord with Subsection b above.)
152
153The source code for a work means the preferred form of the work for
154making modifications to it.  For an executable work, complete source
155code means all the source code for all modules it contains, plus any
156associated interface definition files, plus the scripts used to
157control compilation and installation of the executable.  However, as a
158special exception, the source code distributed need not include
159anything that is normally distributed (in either source or binary
160form) with the major components (compiler, kernel, and so on) of the
161operating system on which the executable runs, unless that component
162itself accompanies the executable.
163
164If distribution of executable or object code is made by offering
165access to copy from a designated place, then offering equivalent
166access to copy the source code from the same place counts as
167distribution of the source code, even though third parties are not
168compelled to copy the source along with the object code.
169  4. You may not copy, modify, sublicense, or distribute the Program
170except as expressly provided under this License.  Any attempt
171otherwise to copy, modify, sublicense or distribute the Program is
172void, and will automatically terminate your rights under this License.
173However, parties who have received copies, or rights, from you under
174this License will not have their licenses terminated so long as such
175parties remain in full compliance.
176
177  5. You are not required to accept this License, since you have not
178signed it.  However, nothing else grants you permission to modify or
179distribute the Program or its derivative works.  These actions are
180prohibited by law if you do not accept this License.  Therefore, by
181modifying or distributing the Program (or any work based on the
182Program), you indicate your acceptance of this License to do so, and
183all its terms and conditions for copying, distributing or modifying
184the Program or works based on it.
185
186  6. Each time you redistribute the Program (or any work based on the
187Program), the recipient automatically receives a license from the
188original licensor to copy, distribute or modify the Program subject to
189these terms and conditions.  You may not impose any further
190restrictions on the recipients' exercise of the rights granted herein.
191You are not responsible for enforcing compliance by third parties to
192this License.
193
194  7. If, as a consequence of a court judgment or allegation of patent
195infringement or for any other reason (not limited to patent issues),
196conditions are imposed on you (whether by court order, agreement or
197otherwise) that contradict the conditions of this License, they do not
198excuse you from the conditions of this License.  If you cannot
199distribute so as to satisfy simultaneously your obligations under this
200License and any other pertinent obligations, then as a consequence you
201may not distribute the Program at all.  For example, if a patent
202license would not permit royalty-free redistribution of the Program by
203all those who receive copies directly or indirectly through you, then
204the only way you could satisfy both it and this License would be to
205refrain entirely from distribution of the Program.
206
207If any portion of this section is held invalid or unenforceable under
208any particular circumstance, the balance of the section is intended to
209apply and the section as a whole is intended to apply in other
210circumstances.
211
212It is not the purpose of this section to induce you to infringe any
213patents or other property right claims or to contest validity of any
214such claims; this section has the sole purpose of protecting the
215integrity of the free software distribution system, which is
216implemented by public license practices.  Many people have made
217generous contributions to the wide range of software distributed
218through that system in reliance on consistent application of that
219system; it is up to the author/donor to decide if he or she is willing
220to distribute software through any other system and a licensee cannot
221impose that choice.
222
223This section is intended to make thoroughly clear what is believed to
224be a consequence of the rest of this License.
225
226  8. If the distribution and/or use of the Program is restricted in
227certain countries either by patents or by copyrighted interfaces, the
228original copyright holder who places the Program under this License
229may add an explicit geographical distribution limitation excluding
230those countries, so that distribution is permitted only in or among
231countries not thus excluded.  In such case, this License incorporates
232the limitation as if written in the body of this License.
233
234  9. The Free Software Foundation may publish revised and/or new versions
235of the General Public License from time to time.  Such new versions will
236be similar in spirit to the present version, but may differ in detail to
237address new problems or concerns.
238
239Each version is given a distinguishing version number.  If the Program
240specifies a version number of this License which applies to it and "any
241later version", you have the option of following the terms and conditions
242either of that version or of any later version published by the Free
243Software Foundation.  If the Program does not specify a version number of
244this License, you may choose any version ever published by the Free Software
245Foundation.
246
247  10. If you wish to incorporate parts of the Program into other free
248programs whose distribution conditions are different, write to the author
249to ask for permission.  For software which is copyrighted by the Free
250Software Foundation, write to the Free Software Foundation; we sometimes
251make exceptions for this.  Our decision will be guided by the two goals
252of preserving the free status of all derivatives of our free software and
253of promoting the sharing and reuse of software generally.
254
255                            NO WARRANTY
256
257  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
258FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
259OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
260PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
261OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
262MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
263TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
264PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
265REPAIR OR CORRECTION.
266
267  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
268WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
269REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
270INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
271OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
272TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
273YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
274PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
275POSSIBILITY OF SUCH DAMAGES.
276
277                     END OF TERMS AND CONDITIONS
