10The General Public License (GPL)
11Version 2, June 1991
12
13Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
14Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
15verbatim copies of this license document, but changing it is not allowed.

17Preamble
18
19The licenses for most software are designed to take away your freedom to share
20and change it. By contrast, the GNU General Public License is intended to
21guarantee your freedom to share and change free software--to make sure the
22software is free for all its users. This General Public License applies to most of
23the Free Software Foundation's software and to any other program whose
24authors commit to using it. (Some other Free Software Foundation software is
25covered by the GNU Library General Public License instead.) You can apply it to
26your programs, too.
27
28When we speak of free software, we are referring to freedom, not price. Our
29General Public Licenses are designed to make sure that you have the freedom
30to distribute copies of free software (and charge for this service if you wish), that
31you receive source code or can get it if you want it, that you can change the
32software or use pieces of it in new free programs; and that you know you can do
33these things.
34
35To protect your rights, we need to make restrictions that forbid anyone to deny
36you these rights or to ask you to surrender the rights. These restrictions
37translate to certain responsibilities for you if you distribute copies of the
38software, or if you modify it.
39
40For example, if you distribute copies of such a program, whether gratis or for a
41fee, you must give the recipients all the rights that you have. You must make
42sure that they, too, receive or can get the source code. And you must show
43them these terms so they know their rights.
44
45We protect your rights with two steps: (1) copyright the software, and (2) offer
46you this license which gives you legal permission to copy, distribute and/or
47modify the software.
48
49Also, for each author's protection and ours, we want to make certain that
50everyone understands that there is no warranty for this free software. If the
51software is modified by someone else and passed on, we want its recipients to
52know that what they have is not the original, so that any problems introduced by
53others will not reflect on the original authors' reputations.
54
55Finally, any free program is threatened constantly by software patents. We wish
56to avoid the danger that redistributors of a free program will individually obtain
57patent licenses, in effect making the program proprietary. To prevent this, we
58have made it clear that any patent must be licensed for everyone's free use or
59not licensed at all.
60
61The precise terms and conditions for copying, distribution and modification
62follow.
63
64GNU GENERAL PUBLIC LICENSE
65TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
66MODIFICATION
67
680. This License applies to any program or other work which contains a notice
69placed by the copyright holder saying it may be distributed under the terms of
70this General Public License. The "Program", below, refers to any such program
71or work, and a "work based on the Program" means either the Program or any
72derivative work under copyright law: that is to say, a work containing the
73Program or a portion of it, either verbatim or with modifications and/or translated
74into another language. (Hereinafter, translation is included without limitation in
75the term "modification".) Each licensee is addressed as "you".
76
77Activities other than copying, distribution and modification are not covered by
78this License; they are outside its scope. The act of running the Program is not
79restricted, and the output from the Program is covered only if its contents
80constitute a work based on the Program (independent of having been made by
81running the Program). Whether that is true depends on what the Program does.
82
831. You may copy and distribute verbatim copies of the Program's source code as
84you receive it, in any medium, provided that you conspicuously and appropriately
85publish on each copy an appropriate copyright notice and disclaimer of warranty;
86keep intact all the notices that refer to this License and to the absence of any
87warranty; and give any other recipients of the Program a copy of this License
88along with the Program.
89
90You may charge a fee for the physical act of transferring a copy, and you may at
91your option offer warranty protection in exchange for a fee.
92
932. You may modify your copy or copies of the Program or any portion of it, thus
94forming a work based on the Program, and copy and distribute such
95modifications or work under the terms of Section 1 above, provided that you also
96meet all of these conditions:
97
98a) You must cause the modified files to carry prominent notices stating that you
99changed the files and the date of any change.
100
101b) You must cause any work that you distribute or publish, that in whole or in
102part contains or is derived from the Program or any part thereof, to be licensed
103as a whole at no charge to all third parties under the terms of this License.
104
105c) If the modified program normally reads commands interactively when run, you
106must cause it, when started running for such interactive use in the most ordinary
107way, to print or display an announcement including an appropriate copyright
108notice and a notice that there is no warranty (or else, saying that you provide a
109warranty) and that users may redistribute the program under these conditions,
110and telling the user how to view a copy of this License. (Exception: if the
111Program itself is interactive but does not normally print such an announcement,
112your work based on the Program is not required to print an announcement.)
113
114These requirements apply to the modified work as a whole. If identifiable
115sections of that work are not derived from the Program, and can be reasonably
116considered independent and separate works in themselves, then this License,
117and its terms, do not apply to those sections when you distribute them as
118separate works. But when you distribute the same sections as part of a whole
119which is a work based on the Program, the distribution of the whole must be on
120the terms of this License, whose permissions for other licensees extend to the
121entire whole, and thus to each and every part regardless of who wrote it.
122
123Thus, it is not the intent of this section to claim rights or contest your rights to
124work written entirely by you; rather, the intent is to exercise the right to control
125the distribution of derivative or collective works based on the Program.
126
127In addition, mere aggregation of another work not based on the Program with the
128Program (or with a work based on the Program) on a volume of a storage or
129distribution medium does not bring the other work under the scope of this
130License.
131
1323. You may copy and distribute the Program (or a work based on it, under
133Section 2) in object code or executable form under the terms of Sections 1 and 2
134above provided that you also do one of the following:
135
136a) Accompany it with the complete corresponding machine-readable source
137code, which must be distributed under the terms of Sections 1 and 2 above on a
138medium customarily used for software interchange; or,
139
140b) Accompany it with a written offer, valid for at least three years, to give any
141third party, for a charge no more than your cost of physically performing source
142distribution, a complete machine-readable copy of the corresponding source
143code, to be distributed under the terms of Sections 1 and 2 above on a medium
144customarily used for software interchange; or,
145
146c) Accompany it with the information you received as to the offer to distribute
147corresponding source code. (This alternative is allowed only for noncommercial
148distribution and only if you received the program in object code or executable
149form with such an offer, in accord with Subsection b above.)
150
151The source code for a work means the preferred form of the work for making
152modifications to it. For an executable work, complete source code means all the
153source code for all modules it contains, plus any associated interface definition
154files, plus the scripts used to control compilation and installation of the
155executable. However, as a special exception, the source code distributed need
156not include anything that is normally distributed (in either source or binary form)
157with the major components (compiler, kernel, and so on) of the operating system
158on which the executable runs, unless that component itself accompanies the
159executable.
160
161If distribution of executable or object code is made by offering access to copy
162from a designated place, then offering equivalent access to copy the source
163code from the same place counts as distribution of the source code, even though
164third parties are not compelled to copy the source along with the object code.
165
1664. You may not copy, modify, sublicense, or distribute the Program except as
167expressly provided under this License. Any attempt otherwise to copy, modify,
168sublicense or distribute the Program is void, and will automatically terminate
169your rights under this License. However, parties who have received copies, or
170rights, from you under this License will not have their licenses terminated so long
171as such parties remain in full compliance.
172
1735. You are not required to accept this License, since you have not signed it.
174However, nothing else grants you permission to modify or distribute the Program
175or its derivative works. These actions are prohibited by law if you do not accept
176this License. Therefore, by modifying or distributing the Program (or any work
177based on the Program), you indicate your acceptance of this License to do so,
178and all its terms and conditions for copying, distributing or modifying the
179Program or works based on it.
180
1816. Each time you redistribute the Program (or any work based on the Program),
182the recipient automatically receives a license from the original licensor to copy,
183distribute or modify the Program subject to these terms and conditions. You
184may not impose any further restrictions on the recipients' exercise of the rights
185granted herein. You are not responsible for enforcing compliance by third parties
186to this License.
187
1887. If, as a consequence of a court judgment or allegation of patent infringement
189or for any other reason (not limited to patent issues), conditions are imposed on
190you (whether by court order, agreement or otherwise) that contradict the
191conditions of this License, they do not excuse you from the conditions of this
192License. If you cannot distribute so as to satisfy simultaneously your obligations
193under this License and any other pertinent obligations, then as a consequence
194you may not distribute the Program at all. For example, if a patent license would
195not permit royalty-free redistribution of the Program by all those who receive
196copies directly or indirectly through you, then the only way you could satisfy
197both it and this License would be to refrain entirely from distribution of the
198Program.
199
200If any portion of this section is held invalid or unenforceable under any particular
201circumstance, the balance of the section is intended to apply and the section as
202a whole is intended to apply in other circumstances.
203
204It is not the purpose of this section to induce you to infringe any patents or other
205property right claims or to contest validity of any such claims; this section has
206the sole purpose of protecting the integrity of the free software distribution
207system, which is implemented by public license practices. Many people have
208made generous contributions to the wide range of software distributed through
209that system in reliance on consistent application of that system; it is up to the
210author/donor to decide if he or she is willing to distribute software through any
211other system and a licensee cannot impose that choice.
212
213This section is intended to make thoroughly clear what is believed to be a
214consequence of the rest of this License.
215
2168. If the distribution and/or use of the Program is restricted in certain countries
217either by patents or by copyrighted interfaces, the original copyright holder who
218places the Program under this License may add an explicit geographical
219distribution limitation excluding those countries, so that distribution is permitted
220only in or among countries not thus excluded. In such case, this License
221incorporates the limitation as if written in the body of this License.
222
2239. The Free Software Foundation may publish revised and/or new versions of the
224General Public License from time to time. Such new versions will be similar in
225spirit to the present version, but may differ in detail to address new problems or
226concerns.
227
228Each version is given a distinguishing version number. If the Program specifies a
229version number of this License which applies to it and "any later version", you
230have the option of following the terms and conditions either of that version or of
231any later version published by the Free Software Foundation. If the Program does
232not specify a version number of this License, you may choose any version ever
233published by the Free Software Foundation.
234
23510. If you wish to incorporate parts of the Program into other free programs
236whose distribution conditions are different, write to the author to ask for
237permission. For software which is copyrighted by the Free Software Foundation,
238write to the Free Software Foundation; we sometimes make exceptions for this.
239Our decision will be guided by the two goals of preserving the free status of all
240derivatives of our free software and of promoting the sharing and reuse of
241software generally.
242
243NO WARRANTY
244
24511. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS
246NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
247APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
248COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
249"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
250IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
251MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
252ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
253PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
254YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
255CORRECTION.
256
25712. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED
258TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY
259WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS
260PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
261GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
262ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
263(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
264RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
265PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
266OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
267BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

274The Artistic License
275
276Preamble
277
278The intent of this document is to state the conditions under which a Package
279may be copied, such that the Copyright Holder maintains some semblance of
280artistic control over the development of the package, while giving the users of the
281package the right to use and distribute the Package in a more-or-less customary
282fashion, plus the right to make reasonable modifications.
283
284Definitions:
285
286-    "Package" refers to the collection of files distributed by the Copyright
287     Holder, and derivatives of that collection of files created through textual
288     modification.
289-    "Standard Version" refers to such a Package if it has not been modified,
290     or has been modified in accordance with the wishes of the Copyright
291     Holder.
292-    "Copyright Holder" is whoever is named in the copyright or copyrights for
293     the package.
294-    "You" is you, if you're thinking about copying or distributing this Package.
295-    "Reasonable copying fee" is whatever you can justify on the basis of
296     media cost, duplication charges, time of people involved, and so on. (You
297     will not be required to justify it to the Copyright Holder, but only to the
298     computing community at large as a market that must bear the fee.)
299-    "Freely Available" means that no fee is charged for the item itself, though
300     there may be fees involved in handling the item. It also means that
301     recipients of the item may redistribute it under the same conditions they
302     received it.
303
3041. You may make and give away verbatim copies of the source form of the
305Standard Version of this Package without restriction, provided that you duplicate
306all of the original copyright notices and associated disclaimers.
307
3082. You may apply bug fixes, portability fixes and other modifications derived from
309the Public Domain or from the Copyright Holder. A Package modified in such a
310way shall still be considered the Standard Version.
311
3123. You may otherwise modify your copy of this Package in any way, provided
313that you insert a prominent notice in each changed file stating how and when
314you changed that file, and provided that you do at least ONE of the following:
315
316     a) place your modifications in the Public Domain or otherwise
317     make them Freely Available, such as by posting said modifications
318     to Usenet or an equivalent medium, or placing the modifications on
319     a major archive site such as ftp.uu.net, or by allowing the
320     Copyright Holder to include your modifications in the Standard
321     Version of the Package.
322
323     b) use the modified Package only within your corporation or
324     organization.
325
326     c) rename any non-standard executables so the names do not
327     conflict with standard executables, which must also be provided,
328     and provide a separate manual page for each non-standard
329     executable that clearly documents how it differs from the Standard
330     Version.
331
332     d) make other distribution arrangements with the Copyright Holder.
333
3344. You may distribute the programs of this Package in object code or executable
335form, provided that you do at least ONE of the following:
336
337     a) distribute a Standard Version of the executables and library
338     files, together with instructions (in the manual page or equivalent)
339     on where to get the Standard Version.
340
341     b) accompany the distribution with the machine-readable source of
342     the Package with your modifications.
343
344     c) accompany any non-standard executables with their
345     corresponding Standard Version executables, giving the
346     non-standard executables non-standard names, and clearly
347     documenting the differences in manual pages (or equivalent),
348     together with instructions on where to get the Standard Version.
349
350     d) make other distribution arrangements with the Copyright Holder.
351
3525. You may charge a reasonable copying fee for any distribution of this Package.
353You may charge any fee you choose for support of this Package. You may not
354charge a fee for this Package itself. However, you may distribute this Package in
355aggregate with other (possibly commercial) programs as part of a larger
356(possibly commercial) software distribution provided that you do not advertise
357this Package as a product of your own.
358
3596. The scripts and library files supplied as input to or produced as output from
360the programs of this Package do not automatically fall under the copyright of this
361Package, but belong to whomever generated them, and may be sold
362commercially, and may be aggregated with this Package.
363
3647. C or perl subroutines supplied by you and linked into this Package shall not
365be considered part of this Package.
366
3678. Aggregation of this Package with a commercial distribution is always permitted
368provided that the use of this Package is embedded; that is, when no overt attempt
369is made to make this Package's interfaces visible to the end user of the
370commercial distribution. Such use shall not be construed as a distribution of
371this Package.
372
3739. The name of the Copyright Holder may not be used to endorse or promote
374products derived from this software without specific prior written permission.
375
37610. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
377IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
378WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR
379PURPOSE.
