108     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
109 Everyone is permitted to copy and distribute verbatim copies
110 of this license document, but changing it is not allowed.
111
112			    Preamble
113
114  The licenses for most software are designed to take away your
115freedom to share and change it.  By contrast, the GNU General Public
116License is intended to guarantee your freedom to share and change free
117software--to make sure the software is free for all its users.  This
118General Public License applies to most of the Free Software
119Foundation's software and to any other program whose authors commit to
120using it.  (Some other Free Software Foundation software is covered by
121the GNU Library General Public License instead.)  You can apply it to
122your programs, too.
123
124  When we speak of free software, we are referring to freedom, not
125price.  Our General Public Licenses are designed to make sure that you
126have the freedom to distribute copies of free software (and charge for
127this service if you wish), that you receive source code or can get it
128if you want it, that you can change the software or use pieces of it
129in new free programs; and that you know you can do these things.
130
131  To protect your rights, we need to make restrictions that forbid
132anyone to deny you these rights or to ask you to surrender the rights.
133These restrictions translate to certain responsibilities for you if you
134distribute copies of the software, or if you modify it.
135
136  For example, if you distribute copies of such a program, whether
137gratis or for a fee, you must give the recipients all the rights that
138you have.  You must make sure that they, too, receive or can get the
139source code.  And you must show them these terms so they know their
140rights.
141
142  We protect your rights with two steps: (1) copyright the software, and
143(2) offer you this license which gives you legal permission to copy,
144distribute and/or modify the software.
145
146  Also, for each author's protection and ours, we want to make certain
147that everyone understands that there is no warranty for this free
148software.  If the software is modified by someone else and passed on, we
149want its recipients to know that what they have is not the original, so
150that any problems introduced by others will not reflect on the original
151authors' reputations.
152
153  Finally, any free program is threatened constantly by software
154patents.  We wish to avoid the danger that redistributors of a free
155program will individually obtain patent licenses, in effect making the
156program proprietary.  To prevent this, we have made it clear that any
157patent must be licensed for everyone's free use or not licensed at all.
158
159  The precise terms and conditions for copying, distribution and
160modification follow.
161
162		    GNU GENERAL PUBLIC LICENSE
163   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
164
165  0. This License applies to any program or other work which contains
166a notice placed by the copyright holder saying it may be distributed
167under the terms of this General Public License.  The "Program", below,
168refers to any such program or work, and a "work based on the Program"
169means either the Program or any derivative work under copyright law:
170that is to say, a work containing the Program or a portion of it,
171either verbatim or with modifications and/or translated into another
172language.  (Hereinafter, translation is included without limitation in
173the term "modification".)  Each licensee is addressed as "you".
174
175Activities other than copying, distribution and modification are not
176covered by this License; they are outside its scope.  The act of
177running the Program is not restricted, and the output from the Program
178is covered only if its contents constitute a work based on the
179Program (independent of having been made by running the Program).
180Whether that is true depends on what the Program does.
181
182  1. You may copy and distribute verbatim copies of the Program's
183source code as you receive it, in any medium, provided that you
184conspicuously and appropriately publish on each copy an appropriate
185copyright notice and disclaimer of warranty; keep intact all the
186notices that refer to this License and to the absence of any warranty;
187and give any other recipients of the Program a copy of this License
188along with the Program.
189
190You may charge a fee for the physical act of transferring a copy, and
191you may at your option offer warranty protection in exchange for a fee.
192
193  2. You may modify your copy or copies of the Program or any portion
194of it, thus forming a work based on the Program, and copy and
195distribute such modifications or work under the terms of Section 1
196above, provided that you also meet all of these conditions:
197
198    a) You must cause the modified files to carry prominent notices
199    stating that you changed the files and the date of any change.
200
201    b) You must cause any work that you distribute or publish, that in
202    whole or in part contains or is derived from the Program or any
203    part thereof, to be licensed as a whole at no charge to all third
204    parties under the terms of this License.
205
206    c) If the modified program normally reads commands interactively
207    when run, you must cause it, when started running for such
208    interactive use in the most ordinary way, to print or display an
209    announcement including an appropriate copyright notice and a
210    notice that there is no warranty (or else, saying that you provide
211    a warranty) and that users may redistribute the program under
212    these conditions, and telling the user how to view a copy of this
213    License.  (Exception: if the Program itself is interactive but
214    does not normally print such an announcement, your work based on
215    the Program is not required to print an announcement.)
216
217These requirements apply to the modified work as a whole.  If
218identifiable sections of that work are not derived from the Program,
219and can be reasonably considered independent and separate works in
220themselves, then this License, and its terms, do not apply to those
221sections when you distribute them as separate works.  But when you
222distribute the same sections as part of a whole which is a work based
223on the Program, the distribution of the whole must be on the terms of
224this License, whose permissions for other licensees extend to the
225entire whole, and thus to each and every part regardless of who wrote it.
226
227Thus, it is not the intent of this section to claim rights or contest
228your rights to work written entirely by you; rather, the intent is to
229exercise the right to control the distribution of derivative or
230collective works based on the Program.
231
232In addition, mere aggregation of another work not based on the Program
233with the Program (or with a work based on the Program) on a volume of
234a storage or distribution medium does not bring the other work under
235the scope of this License.
236
237  3. You may copy and distribute the Program (or a work based on it,
238under Section 2) in object code or executable form under the terms of
239Sections 1 and 2 above provided that you also do one of the following:
240
241    a) Accompany it with the complete corresponding machine-readable
242    source code, which must be distributed under the terms of Sections
243    1 and 2 above on a medium customarily used for software interchange; or,
244
245    b) Accompany it with a written offer, valid for at least three
246    years, to give any third party, for a charge no more than your
247    cost of physically performing source distribution, a complete
248    machine-readable copy of the corresponding source code, to be
249    distributed under the terms of Sections 1 and 2 above on a medium
250    customarily used for software interchange; or,
251
252    c) Accompany it with the information you received as to the offer
253    to distribute corresponding source code.  (This alternative is
254    allowed only for noncommercial distribution and only if you
255    received the program in object code or executable form with such
256    an offer, in accord with Subsection b above.)
257
258The source code for a work means the preferred form of the work for
259making modifications to it.  For an executable work, complete source
260code means all the source code for all modules it contains, plus any
261associated interface definition files, plus the scripts used to
262control compilation and installation of the executable.  However, as a
263special exception, the source code distributed need not include
264anything that is normally distributed (in either source or binary
265form) with the major components (compiler, kernel, and so on) of the
266operating system on which the executable runs, unless that component
267itself accompanies the executable.
268
269If distribution of executable or object code is made by offering
270access to copy from a designated place, then offering equivalent
271access to copy the source code from the same place counts as
272distribution of the source code, even though third parties are not
273compelled to copy the source along with the object code.
274
275  4. You may not copy, modify, sublicense, or distribute the Program
276except as expressly provided under this License.  Any attempt
277otherwise to copy, modify, sublicense or distribute the Program is
278void, and will automatically terminate your rights under this License.
279However, parties who have received copies, or rights, from you under
280this License will not have their licenses terminated so long as such
281parties remain in full compliance.
282
283  5. You are not required to accept this License, since you have not
284signed it.  However, nothing else grants you permission to modify or
285distribute the Program or its derivative works.  These actions are
286prohibited by law if you do not accept this License.  Therefore, by
287modifying or distributing the Program (or any work based on the
288Program), you indicate your acceptance of this License to do so, and
289all its terms and conditions for copying, distributing or modifying
290the Program or works based on it.
291
292  6. Each time you redistribute the Program (or any work based on the
293Program), the recipient automatically receives a license from the
294original licensor to copy, distribute or modify the Program subject to
295these terms and conditions.  You may not impose any further
296restrictions on the recipients' exercise of the rights granted herein.
297You are not responsible for enforcing compliance by third parties to
298this License.
299
300  7. If, as a consequence of a court judgment or allegation of patent
301infringement or for any other reason (not limited to patent issues),
302conditions are imposed on you (whether by court order, agreement or
303otherwise) that contradict the conditions of this License, they do not
304excuse you from the conditions of this License.  If you cannot
305distribute so as to satisfy simultaneously your obligations under this
306License and any other pertinent obligations, then as a consequence you
307may not distribute the Program at all.  For example, if a patent
308license would not permit royalty-free redistribution of the Program by
309all those who receive copies directly or indirectly through you, then
310the only way you could satisfy both it and this License would be to
311refrain entirely from distribution of the Program.
312
313If any portion of this section is held invalid or unenforceable under
314any particular circumstance, the balance of the section is intended to
315apply and the section as a whole is intended to apply in other
316circumstances.
317
318It is not the purpose of this section to induce you to infringe any
319patents or other property right claims or to contest validity of any
320such claims; this section has the sole purpose of protecting the
321integrity of the free software distribution system, which is
322implemented by public license practices.  Many people have made
323generous contributions to the wide range of software distributed
324through that system in reliance on consistent application of that
325system; it is up to the author/donor to decide if he or she is willing
326to distribute software through any other system and a licensee cannot
327impose that choice.
328
329This section is intended to make thoroughly clear what is believed to
330be a consequence of the rest of this License.
331
332  8. If the distribution and/or use of the Program is restricted in
333certain countries either by patents or by copyrighted interfaces, the
334original copyright holder who places the Program under this License
335may add an explicit geographical distribution limitation excluding
336those countries, so that distribution is permitted only in or among
337countries not thus excluded.  In such case, this License incorporates
338the limitation as if written in the body of this License.
339
340  9. The Free Software Foundation may publish revised and/or new versions
341of the General Public License from time to time.  Such new versions will
342be similar in spirit to the present version, but may differ in detail to
343address new problems or concerns.
344
345Each version is given a distinguishing version number.  If the Program
346specifies a version number of this License which applies to it and "any
347later version", you have the option of following the terms and conditions
348either of that version or of any later version published by the Free
349Software Foundation.  If the Program does not specify a version number of
350this License, you may choose any version ever published by the Free Software
351Foundation.
352
353  10. If you wish to incorporate parts of the Program into other free
354programs whose distribution conditions are different, write to the author
355to ask for permission.  For software which is copyrighted by the Free
356Software Foundation, write to the Free Software Foundation; we sometimes
357make exceptions for this.  Our decision will be guided by the two goals
358of preserving the free status of all derivatives of our free software and
359of promoting the sharing and reuse of software generally.
360
361			    NO WARRANTY
362
363  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
364FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
365OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
366PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
367OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
368MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
369TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
370PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
371REPAIR OR CORRECTION.
372
373  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
374WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
375REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
376INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
377OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
378TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
379YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
380PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
381POSSIBILITY OF SUCH DAMAGES.
382
383		     END OF TERMS AND CONDITIONS
384
385	    How to Apply These Terms to Your New Programs
386
387  If you develop a new program, and you want it to be of the greatest
388possible use to the public, the best way to achieve this is to make it
389free software which everyone can redistribute and change under these terms.
390
391  To do so, attach the following notices to the program.  It is safest
392to attach them to the start of each source file to most effectively
393convey the exclusion of warranty; and each file should have at least
394the "copyright" line and a pointer to where the full notice is found.
395
396    <one line to give the program's name and a brief idea of what it does.>
397    Copyright (C) <year>  <name of author>
398
399    This program is free software; you can redistribute it and/or modify
400    it under the terms of the GNU General Public License as published by
401    the Free Software Foundation; either version 2 of the License, or
402    (at your option) any later version.
403
404    This program is distributed in the hope that it will be useful,
405    but WITHOUT ANY WARRANTY; without even the implied warranty of
406    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
407    GNU General Public License for more details.
408
409    You should have received a copy of the GNU General Public License
410    along with this program; if not, write to the Free Software
411    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
412
413
414Also add information on how to contact you by electronic and paper mail.
415
416If the program is interactive, make it output a short notice like this
417when it starts in an interactive mode:
418
419    Gnomovision version 69, Copyright (C) year  name of author
420    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
421    This is free software, and you are welcome to redistribute it
422    under certain conditions; type `show c' for details.
423
424The hypothetical commands `show w' and `show c' should show the appropriate
425parts of the General Public License.  Of course, the commands you use may
426be called something other than `show w' and `show c'; they could even be
427mouse-clicks or menu items--whatever suits your program.
428
429You should also get your employer (if you work as a programmer) or your
430school, if any, to sign a "copyright disclaimer" for the program, if
431necessary.  Here is a sample; alter the names:
432
433  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
434  `Gnomovision' (which makes passes at compilers) written by James Hacker.

437  Ty Coon, President of Vice
438
439This General Public License does not permit incorporating your program into
440proprietary programs.  If your program is a subroutine library, you may
441consider it more useful to permit linking proprietary applications with the
442library.  If this is what you want to do, use the GNU Library General
443Public License instead of this License.
444
