1	+ GNU GENERAL PUBLIC LICENSE
2	+ Version 2, June 1991
3	+
4	+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
5	+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
6	+ Everyone is permitted to copy and distribute verbatim copies
7	+ of this license document, but changing it is not allowed.
8	+
9	+ Preamble
10	+
11	+ The licenses for most software are designed to take away your
12	+ freedom to share and change it. By contrast, the GNU General Public
13	+ License is intended to guarantee your freedom to share and change free
14	+ software--to make sure the software is free for all its users. This
15	+ General Public License applies to most of the Free Software
16	+ Foundation's software and to any other program whose authors commit to
17	+ using it. (Some other Free Software Foundation software is covered by
18	+ the GNU Lesser General Public License instead.) You can apply it to
19	+ your programs, too.
20	+
21	+ When we speak of free software, we are referring to freedom, not
22	+ price. Our General Public Licenses are designed to make sure that you
23	+ have the freedom to distribute copies of free software (and charge for
24	+ this service if you wish), that you receive source code or can get it
25	+ if you want it, that you can change the software or use pieces of it
26	+ in 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
29	+ anyone to deny you these rights or to ask you to surrender the rights.
30	+ These restrictions translate to certain responsibilities for you if you
31	+ distribute copies of the software, or if you modify it.
32	+
33	+ For example, if you distribute copies of such a program, whether
34	+ gratis or for a fee, you must give the recipients all the rights that
35	+ you have. You must make sure that they, too, receive or can get the
36	+ source code. And you must show them these terms so they know their
37	+ rights.
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,
41	+ distribute and/or modify the software.
42	+
43	+ Also, for each author's protection and ours, we want to make certain
44	+ that everyone understands that there is no warranty for this free
45	+ software. If the software is modified by someone else and passed on, we
46	+ want its recipients to know that what they have is not the original, so
47	+ that any problems introduced by others will not reflect on the original
48	+ authors' reputations.
49	+
50	+ Finally, any free program is threatened constantly by software
51	+ patents. We wish to avoid the danger that redistributors of a free
52	+ program will individually obtain patent licenses, in effect making the
53	+ program proprietary. To prevent this, we have made it clear that any
54	+ patent must be licensed for everyone's free use or not licensed at all.
55	+
56	+ The precise terms and conditions for copying, distribution and
57	+ modification follow.
58	+
59	+ GNU GENERAL PUBLIC LICENSE
60	+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
61	+
62	+ 0. This License applies to any program or other work which contains
63	+ 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".
71	+
72	+ Activities other than copying, distribution and modification are not
73	+ covered by this License; they are outside its scope. The act of
74	+ running the Program is not restricted, and the output from the Program
75	+ is covered only if its contents constitute a work based on the
76	+ Program (independent of having been made by running the Program).
77	+ Whether that is true depends on what the Program does.
78	+
79	+ 1. You may copy and distribute verbatim copies of the Program's
80	+ source code as you receive it, in any medium, provided that you
81	+ conspicuously and appropriately publish on each copy an appropriate
82	+ copyright notice and disclaimer of warranty; keep intact all the
83	+ notices that refer to this License and to the absence of any warranty;
84	+ and give any other recipients of the Program a copy of this License
85	+ along with the Program.
86	+
87	+ You may charge a fee for the physical act of transferring a copy, and
88	+ you may at your option offer warranty protection in exchange for a fee.
89	+
90	+ 2. You may modify your copy or copies of the Program or any portion
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:
94	+
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.
97	+
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.
102	+
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.)
113	+
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.
123	+
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.
128	+
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.
133	+
134	+ 3. You may copy and distribute the Program (or a work based on it,
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:
137	+
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,
141	+
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,
148	+
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.)
154	+
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.
165	+
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.
171	+
172	+ 4. You may not copy, modify, sublicense, or distribute the Program
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.
179	+
180	+ 5. You are not required to accept this License, since you have not
181	+ signed it. However, nothing else grants you permission to modify or
182	+ distribute the Program or its derivative works. These actions are
183	+ prohibited by law if you do not accept this License. Therefore, by
184	+ modifying or distributing the Program (or any work based on the
185	+ Program), you indicate your acceptance of this License to do so, and
186	+ all its terms and conditions for copying, distributing or modifying
187	+ the Program or works based on it.
188	+
189	+ 6. Each time you redistribute the Program (or any work based on the
190	+ Program), the recipient automatically receives a license from the
191	+ original licensor to copy, distribute or modify the Program subject to
192	+ these terms and conditions. You may not impose any further
193	+ restrictions on the recipients' exercise of the rights granted herein.
194	+ You are not responsible for enforcing compliance by third parties to
195	+ this License.
196	+
197	+ 7. If, as a consequence of a court judgment or allegation of patent
198	+ infringement or for any other reason (not limited to patent issues),
199	+ conditions are imposed on you (whether by court order, agreement or
200	+ otherwise) that contradict the conditions of this License, they do not
201	+ excuse you from the conditions of this License. If you cannot
202	+ distribute so as to satisfy simultaneously your obligations under this
203	+ License and any other pertinent obligations, then as a consequence you
204	+ may not distribute the Program at all. For example, if a patent
205	+ license would not permit royalty-free redistribution of the Program by
206	+ all those who receive copies directly or indirectly through you, then
207	+ the only way you could satisfy both it and this License would be to
208	+ refrain entirely from distribution of the Program.
209	+
210	+ If any portion of this section is held invalid or unenforceable under
211	+ any particular circumstance, the balance of the section is intended to
212	+ apply and the section as a whole is intended to apply in other
213	+ circumstances.
214	+
215	+ It is not the purpose of this section to induce you to infringe any
216	+ patents or other property right claims or to contest validity of any
217	+ such claims; this section has the sole purpose of protecting the
218	+ integrity of the free software distribution system, which is
219	+ implemented by public license practices. Many people have made
220	+ generous contributions to the wide range of software distributed
221	+ through that system in reliance on consistent application of that
222	+ system; it is up to the author/donor to decide if he or she is willing
223	+ to distribute software through any other system and a licensee cannot
224	+ impose that choice.
225	+
226	+ This section is intended to make thoroughly clear what is believed to
227	+ be a consequence of the rest of this License.
228	+
229	+ 8. If the distribution and/or use of the Program is restricted in
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.
236	+
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.
241	+
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
248	+ Foundation.
249	+
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.
257	+
258	+ NO WARRANTY
259	+
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.
269	+
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.
279	+
280	+ END OF TERMS AND CONDITIONS
