12                          675 Mass Ave, Cambridge, MA 02139, USA
13 Everyone is permitted to copy and distribute verbatim copies
14 of this license document, but changing it is not allowed.
15
16			    Preamble
17
18  The licenses for most software are designed to take away your
19freedom to share and change it.  By contrast, the GNU General Public
20License is intended to guarantee your freedom to share and change free
21software--to make sure the software is free for all its users.  This
22General Public License applies to most of the Free Software
23Foundation's software and to any other program whose authors commit to
24using it.  (Some other Free Software Foundation software is covered by
25the GNU Library General Public License instead.)  You can apply it to
26your programs, too.
27
28  When we speak of free software, we are referring to freedom, not
29price.  Our General Public Licenses are designed to make sure that you
30have the freedom to distribute copies of free software (and charge for
31this service if you wish), that you receive source code or can get it
32if you want it, that you can change the software or use pieces of it
33in new free programs; and that you know you can do these things.
34
35  To protect your rights, we need to make restrictions that forbid
36anyone to deny you these rights or to ask you to surrender the rights.
37These restrictions translate to certain responsibilities for you if you
38distribute copies of the software, or if you modify it.
39
40  For example, if you distribute copies of such a program, whether
41gratis or for a fee, you must give the recipients all the rights that
42you have.  You must make sure that they, too, receive or can get the
43source code.  And you must show them these terms so they know their
44rights.
45
46  We protect your rights with two steps: (1) copyright the software, and
47(2) offer you this license which gives you legal permission to copy,
48distribute and/or modify the software.
49
50  Also, for each author's protection and ours, we want to make certain
51that everyone understands that there is no warranty for this free
52software.  If the software is modified by someone else and passed on, we
53want its recipients to know that what they have is not the original, so
54that any problems introduced by others will not reflect on the original
55authors' reputations.
56
57  Finally, any free program is threatened constantly by software
58patents.  We wish to avoid the danger that redistributors of a free
59program will individually obtain patent licenses, in effect making the
60program proprietary.  To prevent this, we have made it clear that any
61patent must be licensed for everyone's free use or not licensed at all.
62
63  The precise terms and conditions for copying, distribution and
64modification follow.
65
66		    GNU GENERAL PUBLIC LICENSE
67   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
68
69  0. This License applies to any program or other work which contains
70a notice placed by the copyright holder saying it may be distributed
71under the terms of this General Public License.  The "Program", below,
72refers to any such program or work, and a "work based on the Program"
73means either the Program or any derivative work under copyright law:
74that is to say, a work containing the Program or a portion of it,
75either verbatim or with modifications and/or translated into another
76language.  (Hereinafter, translation is included without limitation in
77the term "modification".)  Each licensee is addressed as "you".
78
79Activities other than copying, distribution and modification are not
80covered by this License; they are outside its scope.  The act of
81running the Program is not restricted, and the output from the Program
82is covered only if its contents constitute a work based on the
83Program (independent of having been made by running the Program).
84Whether that is true depends on what the Program does.
85
86  1. You may copy and distribute verbatim copies of the Program's
87source code as you receive it, in any medium, provided that you
88conspicuously and appropriately publish on each copy an appropriate
89copyright notice and disclaimer of warranty; keep intact all the
90notices that refer to this License and to the absence of any warranty;
91and give any other recipients of the Program a copy of this License
92along with the Program.
93
94You may charge a fee for the physical act of transferring a copy, and
95you may at your option offer warranty protection in exchange for a fee.
96
97  2. You may modify your copy or copies of the Program or any portion
98of it, thus forming a work based on the Program, and copy and
99distribute such modifications or work under the terms of Section 1
100above, provided that you also meet all of these conditions:
101
102    a) You must cause the modified files to carry prominent notices
103    stating that you changed the files and the date of any change.
104
105    b) You must cause any work that you distribute or publish, that in
106    whole or in part contains or is derived from the Program or any
107    part thereof, to be licensed as a whole at no charge to all third
108    parties under the terms of this License.
109
110    c) If the modified program normally reads commands interactively
111    when run, you must cause it, when started running for such
112    interactive use in the most ordinary way, to print or display an
113    announcement including an appropriate copyright notice and a
114    notice that there is no warranty (or else, saying that you provide
115    a warranty) and that users may redistribute the program under
116    these conditions, and telling the user how to view a copy of this
117    License.  (Exception: if the Program itself is interactive but
118    does not normally print such an announcement, your work based on
119    the Program is not required to print an announcement.)
120
121These requirements apply to the modified work as a whole.  If
122identifiable sections of that work are not derived from the Program,
123and can be reasonably considered independent and separate works in
124themselves, then this License, and its terms, do not apply to those
125sections when you distribute them as separate works.  But when you
126distribute the same sections as part of a whole which is a work based
127on the Program, the distribution of the whole must be on the terms of
128this License, whose permissions for other licensees extend to the
129entire whole, and thus to each and every part regardless of who wrote it.
130
131Thus, it is not the intent of this section to claim rights or contest
132your rights to work written entirely by you; rather, the intent is to
133exercise the right to control the distribution of derivative or
134collective works based on the Program.
135
136In addition, mere aggregation of another work not based on the Program
137with the Program (or with a work based on the Program) on a volume of
138a storage or distribution medium does not bring the other work under
139the scope of this License.
140
141  3. You may copy and distribute the Program (or a work based on it,
142under Section 2) in object code or executable form under the terms of
143Sections 1 and 2 above provided that you also do one of the following:
144
145    a) Accompany it with the complete corresponding machine-readable
146    source code, which must be distributed under the terms of Sections
147    1 and 2 above on a medium customarily used for software interchange; or,
148
149    b) Accompany it with a written offer, valid for at least three
150    years, to give any third party, for a charge no more than your
151    cost of physically performing source distribution, a complete
152    machine-readable copy of the corresponding source code, to be
153    distributed under the terms of Sections 1 and 2 above on a medium
154    customarily used for software interchange; or,
155
156    c) Accompany it with the information you received as to the offer
157    to distribute corresponding source code.  (This alternative is
158    allowed only for noncommercial distribution and only if you
159    received the program in object code or executable form with such
160    an offer, in accord with Subsection b above.)
161
162The source code for a work means the preferred form of the work for
163making modifications to it.  For an executable work, complete source
164code means all the source code for all modules it contains, plus any
165associated interface definition files, plus the scripts used to
166control compilation and installation of the executable.  However, as a
167special exception, the source code distributed need not include
168anything that is normally distributed (in either source or binary
169form) with the major components (compiler, kernel, and so on) of the
170operating system on which the executable runs, unless that component
171itself accompanies the executable.
172
173If distribution of executable or object code is made by offering
174access to copy from a designated place, then offering equivalent
175access to copy the source code from the same place counts as
176distribution of the source code, even though third parties are not
177compelled to copy the source along with the object code.
178
179  4. You may not copy, modify, sublicense, or distribute the Program
180except as expressly provided under this License.  Any attempt
181otherwise to copy, modify, sublicense or distribute the Program is
182void, and will automatically terminate your rights under this License.
183However, parties who have received copies, or rights, from you under
184this License will not have their licenses terminated so long as such
185parties remain in full compliance.
186
187  5. You are not required to accept this License, since you have not
188signed it.  However, nothing else grants you permission to modify or
189distribute the Program or its derivative works.  These actions are
190prohibited by law if you do not accept this License.  Therefore, by
191modifying or distributing the Program (or any work based on the
192Program), you indicate your acceptance of this License to do so, and
193all its terms and conditions for copying, distributing or modifying
194the Program or works based on it.
195
196  6. Each time you redistribute the Program (or any work based on the
197Program), the recipient automatically receives a license from the
198original licensor to copy, distribute or modify the Program subject to
199these terms and conditions.  You may not impose any further
200restrictions on the recipients' exercise of the rights granted herein.
201You are not responsible for enforcing compliance by third parties to
202this License.
203
204  7. If, as a consequence of a court judgment or allegation of patent
205infringement or for any other reason (not limited to patent issues),
206conditions are imposed on you (whether by court order, agreement or
207otherwise) that contradict the conditions of this License, they do not
208excuse you from the conditions of this License.  If you cannot
209distribute so as to satisfy simultaneously your obligations under this
210License and any other pertinent obligations, then as a consequence you
211may not distribute the Program at all.  For example, if a patent
212license would not permit royalty-free redistribution of the Program by
213all those who receive copies directly or indirectly through you, then
214the only way you could satisfy both it and this License would be to
215refrain entirely from distribution of the Program.
216
217If any portion of this section is held invalid or unenforceable under
218any particular circumstance, the balance of the section is intended to
219apply and the section as a whole is intended to apply in other
220circumstances.
221
222It is not the purpose of this section to induce you to infringe any
223patents or other property right claims or to contest validity of any
224such claims; this section has the sole purpose of protecting the
225integrity of the free software distribution system, which is
226implemented by public license practices.  Many people have made
227generous contributions to the wide range of software distributed
228through that system in reliance on consistent application of that
229system; it is up to the author/donor to decide if he or she is willing
230to distribute software through any other system and a licensee cannot
231impose that choice.
232
233This section is intended to make thoroughly clear what is believed to
234be a consequence of the rest of this License.
235
236  8. If the distribution and/or use of the Program is restricted in
237certain countries either by patents or by copyrighted interfaces, the
238original copyright holder who places the Program under this License
239may add an explicit geographical distribution limitation excluding
240those countries, so that distribution is permitted only in or among
241countries not thus excluded.  In such case, this License incorporates
242the limitation as if written in the body of this License.
243
244  9. The Free Software Foundation may publish revised and/or new versions
245of the General Public License from time to time.  Such new versions will
246be similar in spirit to the present version, but may differ in detail to
247address new problems or concerns.
248
249Each version is given a distinguishing version number.  If the Program
250specifies a version number of this License which applies to it and "any
251later version", you have the option of following the terms and conditions
252either of that version or of any later version published by the Free
253Software Foundation.  If the Program does not specify a version number of
254this License, you may choose any version ever published by the Free Software
255Foundation.
256
257  10. If you wish to incorporate parts of the Program into other free
258programs whose distribution conditions are different, write to the author
259to ask for permission.  For software which is copyrighted by the Free
260Software Foundation, write to the Free Software Foundation; we sometimes
261make exceptions for this.  Our decision will be guided by the two goals
262of preserving the free status of all derivatives of our free software and
263of promoting the sharing and reuse of software generally.
264
265			    NO WARRANTY
266
267  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
268FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
269OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
270PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
271OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
272MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
273TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
274PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
275REPAIR OR CORRECTION.
276
277  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
278WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
279REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
280INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
281OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
282TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
283YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
284PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
285POSSIBILITY OF SUCH DAMAGES.
286
287		     END OF TERMS AND CONDITIONS
288
289	Appendix: How to Apply These Terms to Your New Programs
290
291  If you develop a new program, and you want it to be of the greatest
292possible use to the public, the best way to achieve this is to make it
293free software which everyone can redistribute and change under these terms.
294
295  To do so, attach the following notices to the program.  It is safest
296to attach them to the start of each source file to most effectively
297convey the exclusion of warranty; and each file should have at least
298the "copyright" line and a pointer to where the full notice is found.
299
300    <one line to give the program's name and a brief idea of what it does.>
301    Copyright (C) 19yy  <name of author>
302
303    This program is free software; you can redistribute it and/or modify
304    it under the terms of the GNU General Public License as published by
305    the Free Software Foundation; either version 2 of the License, or
306    (at your option) any later version.
307
308    This program is distributed in the hope that it will be useful,
309    but WITHOUT ANY WARRANTY; without even the implied warranty of
310    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
311    GNU General Public License for more details.
312
313    You should have received a copy of the GNU General Public License
314    along with this program; if not, write to the Free Software
315    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
316
317Also add information on how to contact you by electronic and paper mail.
318
319If the program is interactive, make it output a short notice like this
320when it starts in an interactive mode:
321
322    Gnomovision version 69, Copyright (C) 19yy name of author
323    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
324    This is free software, and you are welcome to redistribute it
325    under certain conditions; type `show c' for details.
326
327The hypothetical commands `show w' and `show c' should show the appropriate
328parts of the General Public License.  Of course, the commands you use may
329be called something other than `show w' and `show c'; they could even be
330mouse-clicks or menu items--whatever suits your program.
331
332You should also get your employer (if you work as a programmer) or your
333school, if any, to sign a "copyright disclaimer" for the program, if
334necessary.  Here is a sample; alter the names:
335
336  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
337  `Gnomovision' (which makes passes at compilers) written by James Hacker.
338
339  <signature of Ty Coon>, 1 April 1989
340  Ty Coon, President of Vice
341
342This General Public License does not permit incorporating your program into
343proprietary programs.  If your program is a subroutine library, you may
344consider it more useful to permit linking proprietary applications with the
345library.  If this is what you want to do, use the GNU Library General
346Public License instead of this License.
347
