22     # GNU GENERAL PUBLIC LICENSE
23     # Version 2, June 1991
24    
25     # Copyright (C) 1989, 1991
26     # Free Software Foundation, Inc.
27     # 675 Mass Ave, Cambridge, MA 02139, USA
28    
29     # Everyone is permitted to copy and distribute verbatim
30     # copies of this license document, but changing it is not
31     # allowed.
32    
33     # Preamble
34    
35     # The licenses for most software are designed to take away
36     # your freedom to share and change it. By contrast, the GNU
37     # General Public License is intended to guarantee your
38     # freedom to share and change free software--to make sure the
39     # software is free for all its users. This General Public
40     # License applies to most of the Free Software Foundation's
41     # software and to any other program whose authors commit to
42     # using it. (Some other Free Software Foundation software is
43     # covered by the GNU Library General Public License
44     # instead.) You can apply it to your programs, too.
45    
46     # When we speak of free software, we are referring to
47     # freedom, not price. Our General Public Licenses are
48     # designed to make sure that you have the freedom to
49     # distribute copies of free software (and charge for this
50     # service if you wish), that you receive source code or can
51     # get it if you want it, that you can change the software or
52     # use pieces of it in new free programs; and that you know
53     # you can do these things.
54    
55     # To protect your rights, we need to make restrictions that
56     # forbid anyone to deny you these rights or to ask you to
57     # surrender the rights. These restrictions translate to
58     # certain responsibilities for you if you distribute copies
59     # of the software, or if you modify it.
60    
61     # For example, if you distribute copies of such a program,
62     # whether gratis or for a fee, you must give the recipients
63     # all the rights that you have. You must make sure that
64     # they, too, receive or can get the source code. And you
65     # must show them these terms so they know their rights.
66    
67     # We protect your rights with two steps: (1) copyright the
68     # software, and (2) offer you this license which gives you
69     # legal permission to copy, distribute and/or modify the
70     # software.
71    
72     # Also, for each author's protection and ours, we want to
73     # make certain that everyone understands that there is no
74     # warranty for this free software. If the software is
75     # modified by someone else and passed on, we want its
76     # recipients to know that what they have is not the original,
77     # so that any problems introduced by others will not reflect
78     # on the original authors' reputations.
79    
80     # Finally, any free program is threatened constantly by
81     # software patents. We wish to avoid the danger that
82     # redistributors of a free program will individually obtain
83     # patent licenses, in effect making the program proprietary.
84     # To prevent this, we have made it clear that any patent must
85     # be licensed for everyone's free use or not licensed at
86     # all.
87    
88     # The precise terms and conditions for copying, distribution
89     # and modification follow.
90    
91     # GNU GENERAL PUBLIC LICENSE
92     # TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
93     # MODIFICATION
94    
95     # 0. This License applies to any program or other work
96     # which contains a notice placed by the copyright holder
97     # saying it may be distributed under the terms of this
98     # General Public License. The "Program", below, refers to
99     # any such program or work, and a "work based on the Program"
100     # means either the Program or any derivative work under
101     # copyright law: that is to say, a work containing the
102     # Program or a portion of it, either verbatim or with
103     # modifications and/or translated into another language.
104     # (Hereinafter, translation is included without limitation in
105     # the term "modification".) Each licensee is addressed as
106     # "you".
107    
108     # Activities other than copying, distribution and
109     # modification are not covered by this License; they are
110     # outside its scope. The act of running the Program is not
111     # restricted, and the output from the Program is covered only
112     # if its contents constitute a work based on the Program
113     # (independent of having been made by running the Program).
114     # Whether that is true depends on what the Program does.
115    
116     # 1. You may copy and distribute verbatim copies of the
117     # Program's source code as you receive it, in any medium,
118     # provided that you conspicuously and appropriately publish
119     # on each copy an appropriate copyright notice and disclaimer
120     # of warranty; keep intact all the notices that refer to this
121     # License and to the absence of any warranty; and give any
122     # other recipients of the Program a copy of this License
123     # along with the Program.
124    
125     # You may charge a fee for the physical act of transferring a
126     # copy, and you may at your option offer warranty protection
127     # in exchange for a fee.
128    
129     # 2. You may modify your copy or copies of the Program or
130     # any portion of it, thus forming a work based on the
131     # Program, and copy and distribute such modifications or work
132     # under the terms of Section 1 above, provided that you also
133     # meet all of these conditions:
134    
135     # a) You must cause the modified files to carry prominent
136     # notices stating that you changed the files and the date
137     # of any change.
138    
139     # b) You must cause any work that you distribute or
140     # publish, that in whole or in part contains or is
141     # derived from the Program or any part thereof, to be
142     # licensed as a whole at no charge to all third parties
143     # under the terms of this License.
144    
145     # c) If the modified program normally reads commands
146     # interactively when run, you must cause it, when started
147     # running for such interactive use in the most ordinary
148     # way, to print or display an announcement including an
149     # appropriate copyright notice and a notice that there is
150     # no warranty (or else, saying that you provide a
151     # warranty) and that users may redistribute the program
152     # under these conditions, and telling the user how to
153     # view a copy of this License. (Exception: if the
154     # Program itself is interactive but does not normally
155     # print such an announcement, your work based on the
156     # Program is not required to print an announcement.)
157    
158     # These requirements apply to the modified work as a whole.
159     # If identifiable sections of that work are not derived from
160     # the Program, and can be reasonably considered independent
161     # and separate works in themselves, then this License, and
162     # its terms, do not apply to those sections when you
163     # distribute them as separate works. But when you distribute
164     # the same sections as part of a whole which is a work based
165     # on the Program, the distribution of the whole must be on
166     # the terms of this License, whose permissions for other
167     # licensees extend to the entire whole, and thus to each and
168     # every part regardless of who wrote it.
169    
170     # Thus, it is not the intent of this section to claim rights
171     # or contest your rights to work written entirely by you;
172     # rather, the intent is to exercise the right to control the
173     # distribution of derivative or collective works based on the
174     # Program.
175    
176     # In addition, mere aggregation of another work not based on
177     # the Program with the Program (or with a work based on the
178     # Program) on a volume of a storage or distribution medium
179     # does not bring the other work under the scope of this
180     # License.
181    
182     # 3. You may copy and distribute the Program (or a work
183     # based on it, under Section 2) in object code or executable
184     # form under the terms of Sections 1 and 2 above provided
185     # that you also do one of the following:
186    
187     # a) Accompany it with the complete corresponding
188     # machine-readable source code, which must be distributed
189     # under the terms of Sections 1 and 2 above on a medium
190     # customarily used for software interchange; or,
191    
192     # b) Accompany it with a written offer, valid for at
193     # least three years, to give any third party, for a
194     # charge no more than your cost of physically performing
195     # source distribution, a complete machine-readable copy
196     # of the corresponding source code, to be distributed
197     # under the terms of Sections 1 and 2 above on a medium
198     # customarily used for software interchange; or,
199    
200     # c) Accompany it with the information you received as to
201     # the offer to distribute corresponding source code.
202     # (This alternative is allowed only for noncommercial
203     # distribution and only if you received the program in
204     # object code or executable form with such an offer, in
205     # accord with Subsection b above.)
206    
207     # The source code for a work means the preferred form of the
208     # work for making modifications to it. For an executable
209     # work, complete source code means all the source code for
210     # all modules it contains, plus any associated interface
211     # definition files, plus the scripts used to control
212     # compilation and installation of the executable. However,
213     # as a special exception, the source code distributed need
214     # not include anything that is normally distributed (in
215     # either source or binary form) with the major components
216     # (compiler, kernel, and so on) of the operating system on
217     # which the executable runs, unless that component itself
218     # accompanies the executable.
219    
220     # If distribution of executable or object code is made by
221     # offering access to copy from a designated place, then
222     # offering equivalent access to copy the source code from the
223     # same place counts as distribution of the source code, even
224     # though third parties are not compelled to copy the source
225     # along with the object code.
226    
227     # 4. You may not copy, modify, sublicense, or distribute
228     # the Program except as expressly provided under this
229     # License. Any attempt otherwise to copy, modify, sublicense
230     # or distribute the Program is void, and will automatically
231     # terminate your rights under this License. However, parties
232     # who have received copies, or rights, from you under this
233     # License will not have their licenses terminated so long as
234     # such parties remain in full compliance.
235    
236     # 5. You are not required to accept this License, since you
237     # have not signed it. However, nothing else grants you
238     # permission to modify or distribute the Program or its
239     # derivative works. These actions are prohibited by law if
240     # you do not accept this License. Therefore, by modifying or
241     # distributing the Program (or any work based on the
242     # Program), you indicate your acceptance of this License to
243     # do so, and all its terms and conditions for copying,
244     # distributing or modifying the Program or works based on
245     # it.
246    
247     # 6. Each time you redistribute the Program (or any work
248     # based on the Program), the recipient automatically receives
249     # a license from the original licensor to copy, distribute or
250     # modify the Program subject to these terms and conditions.
251     # You may not impose any further restrictions on the
252     # recipients' exercise of the rights granted herein. You are
253     # not responsible for enforcing compliance by third parties
254     # to this License.
255    
256     # 7. If, as a consequence of a court judgment or allegation
257     # of patent infringement or for any other reason (not limited
258     # to patent issues), conditions are imposed on you (whether
259     # by court order, agreement or otherwise) that contradict the
260     # conditions of this License, they do not excuse you from the
261     # conditions of this License. If you cannot distribute so as
262     # to satisfy simultaneously your obligations under this
263     # License and any other pertinent obligations, then as a
264     # consequence you may not distribute the Program at all. For
265     # example, if a patent license would not permit royalty-free
266     # redistribution of the Program by all those who receive
267     # copies directly or indirectly through you, then the only
268     # way you could satisfy both it and this License would be to
269     # refrain entirely from distribution of the Program.
270    
271     # If any portion of this section is held invalid or
272     # unenforceable under any particular circumstance, the
273     # balance of the section is intended to apply and the section
274     # as a whole is intended to apply in other circumstances.
275    
276     # It is not the purpose of this section to induce you to
277     # infringe any patents or other property right claims or to
278     # contest validity of any such claims; this section has the
279     # sole purpose of protecting the integrity of the free
280     # software distribution system, which is implemented by
281     # public license practices. Many people have made generous
282     # contributions to the wide range of software distributed
283     # through that system in reliance on consistent application
284     # of that system; it is up to the author/donor to decide if
285     # he or she is willing to distribute software through any
286     # other system and a licensee cannot impose that choice.
287    
288     # This section is intended to make thoroughly clear what is
289     # believed to be a consequence of the rest of this License.
290    
291     # 8. If the distribution and/or use of the Program is
292     # restricted in certain countries either by patents or by
293     # copyrighted interfaces, the original copyright holder who
294     # places the Program under this License may add an explicit
295     # geographical distribution limitation excluding those
296     # countries, so that distribution is permitted only in or
297     # among countries not thus excluded. In such case, this
298     # License incorporates the limitation as if written in the
299     # body of this License.
300    
301     # 9. The Free Software Foundation may
302     # publish revised and/or new versions of the General Public
303     # License from time to time. Such new versions will be
304     # similar in spirit to the present version, but may differ in
305     # detail to address new problems or concerns.
306    
307     # Each version is given a distinguishing version number. If
308     # the Program specifies a version number of this License
309     # which applies to it and "any later version", you have the
310     # option of following the terms and conditions either of that
311     # version or of any later version published by the Free
312     # Software Foundation. If the Program does not specify a
313     # version number of this License, you may choose any version
314     # ever published by the Free Software Foundation.
315    
316     # 10. If you wish to incorporate parts of the Program into
317     # other free programs whose distribution conditions are
318     # different, write to the author to ask for permission. For
319     # software which is copyrighted by the Free Software
320     # Foundation, write to the Free Software Foundation; we
321     # sometimes make exceptions for this. Our decision will be
322     # guided by the two goals of preserving the free status of
323     # all derivatives of our free software and of promoting the
324     # sharing and reuse of software generally.
325    
326     # NO WARRANTY
327    
328     # 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE
329     # IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
330     # APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING
331     # THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
332     # PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
333     # EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
334     # IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
335     # PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
336     # PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
337     # PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
338     # SERVICING, REPAIR OR CORRECTION.
339    
340     # 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR
341     # AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY
342     # OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
343     # AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
344     # ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
345     # ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
346     # (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
347     # RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
348     # PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
349     # OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
350     # BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
351    
352     # END OF TERMS AND CONDITIONS
353    
354    
355    
356    
357     # How to Apply These Terms to Your New Programs
358    
359     # If you develop a new program, and you want it to be of
360     # the greatest possible use to the public, the best way to
361     # achieve this is to make it free software which everyone can
362     # redistribute and change under these terms.
363    
364     # To do so, attach the following notices to the program.
365     # It is safest to attach them to the start of each source
366     # file to most effectively convey the exclusion of warranty;
367     # and each file should have at least the "copyright" line and
368     # a pointer to where the full notice is found.
