100 Everyone is permitted to copy and distribute verbatim copies
101 of this license document, but changing it is not allowed.
102
103			    Preamble
104
105  The licenses for most software are designed to take away your
106freedom to share and change it.  By contrast, the GNU General Public
107License is intended to guarantee your freedom to share and change free
108software--to make sure the software is free for all its users.  This
109General Public License applies to most of the Free Software
110Foundation's software and to any other program whose authors commit to
111using it.  (Some other Free Software Foundation software is covered by
112the GNU Library General Public License instead.)  You can apply it to
113your programs, too.
114
115  When we speak of free software, we are referring to freedom, not
116price.  Our General Public Licenses are designed to make sure that you
117have the freedom to distribute copies of free software (and charge for
118this service if you wish), that you receive source code or can get it
119if you want it, that you can change the software or use pieces of it
120in new free programs; and that you know you can do these things.
121
122  To protect your rights, we need to make restrictions that forbid
123anyone to deny you these rights or to ask you to surrender the rights.
124These restrictions translate to certain responsibilities for you if you
125distribute copies of the software, or if you modify it.
126
127  For example, if you distribute copies of such a program, whether
128gratis or for a fee, you must give the recipients all the rights that
129you have.  You must make sure that they, too, receive or can get the
130source code.  And you must show them these terms so they know their
131rights.
132
133  We protect your rights with two steps: (1) copyright the software, and
134(2) offer you this license which gives you legal permission to copy,
135distribute and/or modify the software.
136
137  Also, for each author's protection and ours, we want to make certain
138that everyone understands that there is no warranty for this free
139software.  If the software is modified by someone else and passed on, we
140want its recipients to know that what they have is not the original, so
141that any problems introduced by others will not reflect on the original
142authors' reputations.
143
144  Finally, any free program is threatened constantly by software
145patents.  We wish to avoid the danger that redistributors of a free
146program will individually obtain patent licenses, in effect making the
147program proprietary.  To prevent this, we have made it clear that any
148patent must be licensed for everyone's free use or not licensed at all.
149
150  The precise terms and conditions for copying, distribution and
151modification follow.
152
153		    GNU GENERAL PUBLIC LICENSE
154   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
155
156  0. This License applies to any program or other work which contains
157a notice placed by the copyright holder saying it may be distributed
158under the terms of this General Public License.  The "Program", below,
159refers to any such program or work, and a "work based on the Program"
160means either the Program or any derivative work under copyright law:
161that is to say, a work containing the Program or a portion of it,
162either verbatim or with modifications and/or translated into another
163language.  (Hereinafter, translation is included without limitation in
164the term "modification".)  Each licensee is addressed as "you".
165
166Activities other than copying, distribution and modification are not
167covered by this License; they are outside its scope.  The act of
168running the Program is not restricted, and the output from the Program
169is covered only if its contents constitute a work based on the
170Program (independent of having been made by running the Program).
171Whether that is true depends on what the Program does.
172
173  1. You may copy and distribute verbatim copies of the Program's
174source code as you receive it, in any medium, provided that you
175conspicuously and appropriately publish on each copy an appropriate
176copyright notice and disclaimer of warranty; keep intact all the
177notices that refer to this License and to the absence of any warranty;
178and give any other recipients of the Program a copy of this License
179along with the Program.
180
181You may charge a fee for the physical act of transferring a copy, and
182you may at your option offer warranty protection in exchange for a fee.
183
184  2. You may modify your copy or copies of the Program or any portion
185of it, thus forming a work based on the Program, and copy and
186distribute such modifications or work under the terms of Section 1
187above, provided that you also meet all of these conditions:
188
189    a) You must cause the modified files to carry prominent notices
190    stating that you changed the files and the date of any change.
191
192    b) You must cause any work that you distribute or publish, that in
193    whole or in part contains or is derived from the Program or any
194    part thereof, to be licensed as a whole at no charge to all third
195    parties under the terms of this License.
196
197    c) If the modified program normally reads commands interactively
198    when run, you must cause it, when started running for such
199    interactive use in the most ordinary way, to print or display an
200    announcement including an appropriate copyright notice and a
201    notice that there is no warranty (or else, saying that you provide
202    a warranty) and that users may redistribute the program under
203    these conditions, and telling the user how to view a copy of this
204    License.  (Exception: if the Program itself is interactive but
205    does not normally print such an announcement, your work based on
206    the Program is not required to print an announcement.)
207
208These requirements apply to the modified work as a whole.  If
209identifiable sections of that work are not derived from the Program,
210and can be reasonably considered independent and separate works in
211themselves, then this License, and its terms, do not apply to those
212sections when you distribute them as separate works.  But when you
213distribute the same sections as part of a whole which is a work based
214on the Program, the distribution of the whole must be on the terms of
215this License, whose permissions for other licensees extend to the
216entire whole, and thus to each and every part regardless of who wrote it.
217
218Thus, it is not the intent of this section to claim rights or contest
219your rights to work written entirely by you; rather, the intent is to
220exercise the right to control the distribution of derivative or
221collective works based on the Program.
222
223In addition, mere aggregation of another work not based on the Program
224with the Program (or with a work based on the Program) on a volume of
225a storage or distribution medium does not bring the other work under
226the scope of this License.
227
228  3. You may copy and distribute the Program (or a work based on it,
229under Section 2) in object code or executable form under the terms of
230Sections 1 and 2 above provided that you also do one of the following:
231
232    a) Accompany it with the complete corresponding machine-readable
233    source code, which must be distributed under the terms of Sections
234    1 and 2 above on a medium customarily used for software interchange; or,
235
236    b) Accompany it with a written offer, valid for at least three
237    years, to give any third party, for a charge no more than your
238    cost of physically performing source distribution, a complete
239    machine-readable copy of the corresponding source code, to be
240    distributed under the terms of Sections 1 and 2 above on a medium
241    customarily used for software interchange; or,
242
243    c) Accompany it with the information you received as to the offer
244    to distribute corresponding source code.  (This alternative is
245    allowed only for noncommercial distribution and only if you
246    received the program in object code or executable form with such
247    an offer, in accord with Subsection b above.)
248
249The source code for a work means the preferred form of the work for
250making modifications to it.  For an executable work, complete source
251code means all the source code for all modules it contains, plus any
252associated interface definition files, plus the scripts used to
253control compilation and installation of the executable.  However, as a
254special exception, the source code distributed need not include
255anything that is normally distributed (in either source or binary
256form) with the major components (compiler, kernel, and so on) of the
257operating system on which the executable runs, unless that component
258itself accompanies the executable.
259
260If distribution of executable or object code is made by offering
261access to copy from a designated place, then offering equivalent
262access to copy the source code from the same place counts as
263distribution of the source code, even though third parties are not
264compelled to copy the source along with the object code.
265
266  4. You may not copy, modify, sublicense, or distribute the Program
267except as expressly provided under this License.  Any attempt
268otherwise to copy, modify, sublicense or distribute the Program is
269void, and will automatically terminate your rights under this License.
270However, parties who have received copies, or rights, from you under
271this License will not have their licenses terminated so long as such
272parties remain in full compliance.
273
274  5. You are not required to accept this License, since you have not
275signed it.  However, nothing else grants you permission to modify or
276distribute the Program or its derivative works.  These actions are
277prohibited by law if you do not accept this License.  Therefore, by
278modifying or distributing the Program (or any work based on the
279Program), you indicate your acceptance of this License to do so, and
280all its terms and conditions for copying, distributing or modifying
281the Program or works based on it.
282
283  6. Each time you redistribute the Program (or any work based on the
284Program), the recipient automatically receives a license from the
285original licensor to copy, distribute or modify the Program subject to
286these terms and conditions.  You may not impose any further
287restrictions on the recipients' exercise of the rights granted herein.
288You are not responsible for enforcing compliance by third parties to
289this License.
290
291  7. If, as a consequence of a court judgment or allegation of patent
292infringement or for any other reason (not limited to patent issues),
293conditions are imposed on you (whether by court order, agreement or
294otherwise) that contradict the conditions of this License, they do not
295excuse you from the conditions of this License.  If you cannot
296distribute so as to satisfy simultaneously your obligations under this
297License and any other pertinent obligations, then as a consequence you
298may not distribute the Program at all.  For example, if a patent
299license would not permit royalty-free redistribution of the Program by
300all those who receive copies directly or indirectly through you, then
301the only way you could satisfy both it and this License would be to
302refrain entirely from distribution of the Program.
303
304If any portion of this section is held invalid or unenforceable under
305any particular circumstance, the balance of the section is intended to
306apply and the section as a whole is intended to apply in other
307circumstances.
308
309It is not the purpose of this section to induce you to infringe any
310patents or other property right claims or to contest validity of any
311such claims; this section has the sole purpose of protecting the
312integrity of the free software distribution system, which is
313implemented by public license practices.  Many people have made
314generous contributions to the wide range of software distributed
315through that system in reliance on consistent application of that
316system; it is up to the author/donor to decide if he or she is willing
317to distribute software through any other system and a licensee cannot
318impose that choice.
319
320This section is intended to make thoroughly clear what is believed to
321be a consequence of the rest of this License.
322
323  8. If the distribution and/or use of the Program is restricted in
324certain countries either by patents or by copyrighted interfaces, the
325original copyright holder who places the Program under this License
326may add an explicit geographical distribution limitation excluding
327those countries, so that distribution is permitted only in or among
328countries not thus excluded.  In such case, this License incorporates
329the limitation as if written in the body of this License.
330
331  9. The Free Software Foundation may publish revised and/or new versions
332of the General Public License from time to time.  Such new versions will
333be similar in spirit to the present version, but may differ in detail to
334address new problems or concerns.
335
336Each version is given a distinguishing version number.  If the Program
337specifies a version number of this License which applies to it and "any
338later version", you have the option of following the terms and conditions
339either of that version or of any later version published by the Free
340Software Foundation.  If the Program does not specify a version number of
341this License, you may choose any version ever published by the Free Software
342Foundation.
343
344  10. If you wish to incorporate parts of the Program into other free
345programs whose distribution conditions are different, write to the author
346to ask for permission.  For software which is copyrighted by the Free
347Software Foundation, write to the Free Software Foundation; we sometimes
348make exceptions for this.  Our decision will be guided by the two goals
349of preserving the free status of all derivatives of our free software and
350of promoting the sharing and reuse of software generally.
351
352			    NO WARRANTY
353
354  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
355FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
356OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
357PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
358OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
359MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
360TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
361PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
362REPAIR OR CORRECTION.
363
364  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
365WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
366REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
367INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
368OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
369TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
370YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
371PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
372POSSIBILITY OF SUCH DAMAGES.
373
374		     END OF TERMS AND CONDITIONS
375
376	    How to Apply These Terms to Your New Programs
377
378  If you develop a new program, and you want it to be of the greatest
379possible use to the public, the best way to achieve this is to make it
380free software which everyone can redistribute and change under these terms.
381
382  To do so, attach the following notices to the program.  It is safest
383to attach them to the start of each source file to most effectively
384convey the exclusion of warranty; and each file should have at least
385the "copyright" line and a pointer to where the full notice is found.
386
387    <one line to give the program's name and a brief idea of what it does.>
388    Copyright (C) <year>  <name of author>
389
390    This program is free software; you can redistribute it and/or modify
391    it under the terms of the GNU General Public License as published by
392    the Free Software Foundation; either version 2 of the License, or
393    (at your option) any later version.
394
395    This program is distributed in the hope that it will be useful,
396    but WITHOUT ANY WARRANTY; without even the implied warranty of
397    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
398    GNU General Public License for more details.
399
400    You should have received a copy of the GNU General Public License
401    along with this program; if not, write to the Free Software
402    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
403
404
405Also add information on how to contact you by electronic and paper mail.
406
407If the program is interactive, make it output a short notice like this
408when it starts in an interactive mode:
409
410    Gnomovision version 69, Copyright (C) year  name of author
411    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
412    This is free software, and you are welcome to redistribute it
413    under certain conditions; type `show c' for details.
414
415The hypothetical commands `show w' and `show c' should show the appropriate
416parts of the General Public License.  Of course, the commands you use may
417be called something other than `show w' and `show c'; they could even be
418mouse-clicks or menu items--whatever suits your program.
419
420You should also get your employer (if you work as a programmer) or your
421school, if any, to sign a "copyright disclaimer" for the program, if
422necessary.  Here is a sample; alter the names:
423
424  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
425  `Gnomovision' (which makes passes at compilers) written by James Hacker.

428  Ty Coon, President of Vice
429
430This General Public License does not permit incorporating your program into
431proprietary programs.  If your program is a subroutine library, you may
432consider it more useful to permit linking proprietary applications with the
433library.  If this is what you want to do, use the GNU Library General
434Public License instead of this License.
435
